Older people share surprising and simple ways they keep their brains healthy and sharp.

One of the biggest battles of healthy aging is staying mentally sharp. Having a healthy brain is important for mental and physical longevity.

Data from the Centers for Disease Control and Prevention (CDC) reports that 6.7 million older adults in the United States have Alzheimer’s disease, the most common type of dementia. The CDC notes that by 2060, that number will double.

However, being proactive about brain health can help keep aging brains thriving. In an online forum of Boomers and older Gen Xers, they opened up on how they keep their brains sharp and memory strong. These are 40 surprising (and simple) ways they've maintained healthy brains as they've aged.

"I take on-line college courses. Pick one out that piques my interest and sign up. The advantage at my age is I can study whatever I want, I'm not really concerned with advancing my career. Ancient Mediterranean History? Sure why not? History of Beer? Why not? Psychology of Evil? Sounds interesting. All on-line, all cheap. Keeps my brain active." - mike11172

"I'm way into fitness and still work out with weights. Also walk a lot and do fun things outdoors. I make sure that I get outside at least an hour every day. I'm careful to eat good foods that meet nutritional requirements, especially since I work out. I drink plenty of fresh filtered water. Taking care of your health in these three ways really makes a difference in one's mental sharpness and attitude. I belong to a religion that encourages me to treat others kindly and to be thankful for the life I have. Participate in activities that involve helping others. That really makes anybody feel good, have a purpose, and be glad they have the means to give of themselves. My husband and I make a point to always treat each other like we're newlyweds. Keeping the stress in your home to a minimum improves your mental state. In my down time, I've gotten into paper art. It's fun and an easy way for anyone to stay creative. I make cute things and greeting cards for others." - Bebe_Bleau

"I write novels and memoir essays. The novels require a lot of research about settings and history. Unexpectedly, even the memoirs require research, because I took for granted behaviors and ideas that need to be explained for modern readers since nobody takes them for granted anymore. I volunteer for a local organization that helps provide food and medicine to households who have run out of money before the next paycheck. I work with recent immigrants who speak little English and am constantly learning new things about what it's like to struggle for survival in lives of utter poverty." - Building_a_life

"Just use it. The brain works a lot like muscles in the sense that it will degrade quickly if you don't use it but can maintain its abilities for a long ass time if you do use it. I've met so many older people who basically just stop doing anything that requires a lot of thought when they get older because thinking is a lot of work. And you can definitely tell that kind of person when interacting with them. Conversations with them feel more like talking with a bunch of pre-recorded responses. Just do stuff that requires a lot of thought. Learn new skills. Read about complex, interesting ideas. Do puzzles. Play chess." - Yak-5000

Science confirms viral theory about inheriting your mom's nervous system—and it explains a lot

“My mom really said, ‘Double it and give it to the next person.’”

Mother struggling to comfort her child.

Think about the last time your mom—whom you love and cherish—handled a situation poorly. Maybe she lost her temper while waiting to "speak to a representative" on the phone, or raised her voice in a moment that didn't warrant it. To be clear, mothers are not the only ones who lose their cool (we'll save analyzing your other family members' questionable behaviors for another time). But since they contribute 50% of our DNA, their unique responses to stress—their triggers, defense mechanisms, and attempts at self-soothing—deserve a second look. Because, as hoards of people on TikTok are now discovering, we inherit far more than just eye color and a winning smile from our moms.

Thanks to a viral video posted by TikTok user @sierraalexndraa (also known as Sierra Saltz, a chronic illness advocate and content creator who uses her platform to explore the connections between health, energy, and intentional living), people are discovering the complex, surprising world of genetic inheritance. The post, which has garnered 15 million views and 2.4 million likes, has sparked intense discussions about passed-on family traits, inherited emotional regulation, and that maybe, we really have no choice but to turn into our mothers.

@sierralexandraa
Did you know we inherit our mothers nervous system. #creatorsearchinsights #nervoussystemregulation #neuroception #epigenetics #neurospicy #fyp

"Did you know that you didn't just inherit your mom's genes, you inherited her nervous system, too?" Sierra asks. "From the moment we're in the womb, we're absorbing our mother's emotional state, her stress levels, and even the way she regulates her own nervous system."

The news shocked the Internet, with comments ranging from vulnerable ("You forgot to hold my hand 🥺," wrote one person) to outright denial ("Great, thank you, wish it didn't, moving on," replied another).

But the most common response? "Well, this explains a lot…"

via GIPHY

But is Sierra’s claim really true? Do we really inherit our mother’s nervous system? There was only one way to find out: We turned to science to try to explain this phenomenon. Here’s what we found.

The science behind “inheriting your mother’s nervous system”

Mitochondria tells the story. Yes, you inherit your mom’s nervous system—and your dad’s, too, don't forget. “It’s one of the basic tenets of biology: We get our DNA from our mom and our dad,” explains medical science writer Lisa Marshall. “But one notable exception has perplexed scientists for decades.”

It’s the mitochondria, the famed “powerhouse of the cell.”

mothers, science, mitochondria, genetics, nervous system The mitochondria is the powerhouse of the cell. Photo credit: Canva

Humans, along with most animals, only inherit mitochondrial DNA from their mothers—the result of a strange anomaly in the procreation cycle, as “all traces” of the male mitochondrial genome are obliterated the moment the sperm meets egg.

Why is this important? Well, it turns out that mitochondria are involved in almost every aspect of the human body. “The nervous system cannot possibly function without the mitochondria,” explain Dutch psychological scientist Peter Kramer and research scientist Paola Bressan in the research article titled “Our (Mother’s) Mitochondria and Our Mind.”

Besides providing our bodies with energy, these specialized powerhouses also regulate calcium in neurons, ensures synapse formation and the creation of new neurons, and maintains the delicate balance between cell survival and programmed cell death (apoptosis). Which might sound like a bunch of A.P. Biology buzzwords shoved together, for those not in the medical field.

But just imagine the humble mitochondria, working overtime to make sure everything’s in order: that our senses work, our motive skills are up-to-code, memories are created, and hormones are properly released. Unbeknownst to most, the mitochondria in our bodies are taking care of us. Almost like… a mom.

via GIPHY

But when things go haywire, a bunch of problems tend to follow. “A place where mitochondrial trouble occurs frequently is the brain,” writes Kramer and Bressan. So, “it is hardly accidental that their malfunctioning has been associated with virtually every mental or neurological affliction on earth, including chronic psychological stress and fatigue, cognitive deficits, Alzheimer’s and Parkinson’s disease, anxiety, depression, bipolar disorder, schizophrenia, autism, multiple sclerosis, and Down syndrome.”

It’s not just genetics. Beyond the cellular level, a child’s ability to tolerate stress and self-soothe begins in the womb. Research suggests that chronic maternal stress experienced during pregnancy isn't just felt by the mom, but her baby as well—potentially wreaking havoc on the child’s stress-response systems before they're even born, which could lead to future psychological complexes around relaxation and emotional equilibrium.

There’s a unique mother-daughter connection, too. A groundbreaking UC San Francisco study found that the corticolimbic system—a fancy term for the part of the brain that’s in charge of emotional regulation and is often linked with mood disorders—is “more likely to be passed down from mothers to daughters” than to sons.

There’s no need to panic

While there's a clear connection between your nervous system and your mom's, it's important to understand that this isn't the complete story. As Dr. Fumiko Hoeft, a UCSF associate professor of psychiatry who led that groundbreaking study, stresses, "The finding does not mean that mothers are necessarily responsible for their daughters' depression. Many factors play a role in depression—genes that are not inherited from the mother, social environment and life experiences, to name only three. Mother-daughter transmission is just one piece of it."

Also, give your mom some credit! “We are more likely to inherit the good and the bad parts of our mother’s nervous system,” Dr. Natalie Jones, a licensed psychotherapist, says. “If your mother is calm, nurturing, and manages stress well, chances are you are likely to manage things in a similar fashion.”

Inheritance does not equal destiny

The mitochondria given to you at birth are just that—nothing more. Even nervous systems can be rewired (once you're out of the womb, that is). Through engaging in neuroplasticity-boosting activities daily, like physical exercise, learning new skills (hello, Duolingo), and mind-body techniques like yoga and meditation that lower stress hormones, your nervous system can be profoundly reshaped. Your mitochondria will thank you.

Psychologists discover the 'key' element that helps your brain stay sharp in old age

It took 10 years to get the answer.

A graduate, a teacher, and woman reading a book.

Why are some people mentally sharp as they reach their late 80s, while others begin to have “senior moments” in their 60s and have a sharp mental decline thereafter? A recent study published in Psychological Science has found that the key component to remaining mentally sharp into advanced age is having a sense of purpose.

The study was led by Dr. Gabrielle Pfund of Auburn University and colleagues from Rush University and Washington University in St. Louis. “I have been interested in the construct of sense of purpose since early in my graduate school experience,” Pfund said, according to PsyPost. “As I continued throughout graduate school, I came across more and more research that highlighted the predictive power of purpose, particularly for healthy aging. Like many, I’ve personally experienced the pain of losing a loved one to dementia.”

Why is it so important to have a sense of purpose?

Pfund and her team learned the importance of purpose after conducting a study on 1,702 people, 65 years old and older, and asking them about their mental sharpness and levels of well-being for up to 10 years.

“This study focuses on the reciprocal relationship between cognitive function with three domains of well-being: (1) sense of purpose (the extent to which one feels they have personally meaningful goals and activities), (2) eudaimonic well-being (one’s sense of autonomy, personal growth, purpose, and connection to others), and (3) life satisfaction (one’s sense of contentment with their life),” Pfund explained.

The study found that people with a sense of purpose were likely to keep their mental sharpness, and when people experience cognitive decline, it has a greater effect on their sense of purpose than on general life satisfaction. “I expected the findings to be stronger for sense of purpose than life satisfaction, and that ended up being the case,” Pfund said.

What is a sense of purpose?

Pfund’s study should make many consider whether they have a sense of purpose, especially as they get older and risk cognitive decline. But what type of purpose should we consider?

“Sense of purpose can be understood as the extent to which one feels that they have personally meaningful goals and directions guiding them through life,” Pfund said on The Mental Wellbeing Podcast. “So rather than saying ‘I have a purpose in life’ or ‘I do not,’ it's ‘how purposeful do I feel? ‘How high is my sense of purpose?’”

How do I find my life’s purpose?

Pfund believes that a top-down approach, which involves thinking of our purpose and organizing our day-to-day lives around it, can be overwhelming. Instead, she recommends a bottom-down approach that starts with examining our daily interactions.

“Think about as you're going throughout your day, where are the moments that you feel purposeful? That short-term momentary experience of purpose. If you feel purposeful when you're spending time with your friends or when you're learning new information, reading a good book, making podcasts,” she told Indi, the show's host. “If you're able to identify moments where you feel purposeful, then, over time, maybe you can use those moments to find similarities and what all of these experiences have and start to figure out … what your purpose in life may be.”

NYT games like Wordle and Connections are good for cognitive health, with one big caveat

How you feel about doing them matters more than you might think.

Millions of people enjoy NYT Games puzzles like Wordle.

Every morning, I sit down with my cup of coffee, open up the New York Times Games app on my phone, and do the Wordle, Connections, Strands, and Mini-Crossword, in that order. As I complete each game, I send my results to the "Puzzle Pals Gang" group chat I have with some friends and family. We compare. We gloat. We trash talk. We congratulate. It's a delightful routine.

And we're not the only ones. According to the New York Times, there were 4.8 billion plays of Wordle, 2.3 billion plays of Connections, and 8 billion game and puzzle plays total in 2023. A whole lot of people love their brain games.

I like to think I'm benefiting from a nice little brain workout when I do those puzzles, but am I really? According to Mark Alberts, MD, chief of neurology at Hartford Hospital and co-physician-in-chief at the Ayer Neuroscience Institute, I probably am—but that doesn't mean everyone else is.

"These sorts of brain exercises can be very helpful for improving your ability to think and remember,” Alberts says, but that's only true if you're someone who actually likes and enjoys doing them. People who find the games fun can enjoy a boost in memory, attention and other cognitive functions. But for those who just find them stressful or frustrating, the cognitive benefit doesn't outweigh the negative impacts.

“Sure, crossword puzzles and Sudoku could be fun for some people. But if they’re distressing to you—or just not fun—they won’t be beneficial,” says Dr. Alberts.

puzzle write GIFGiphy

As someone who loves games and puzzles, I'm surely reaping the cognitive benefits. Someone who gets super stressed out by them would not, but that doesn't mean there aren't other ways for people who don't enjoy games to give their own brains a boost.

“Emotional well-being has a huge impact on cognition, so it’s important to choose activities that give you joy,” says Dr. Alberts. “Find a different hobby. Take a class. Teach a class! Keep learning in other ways.”

And, of course, there's not widespread agreement on the degree to which these games are helpful to brain health, either. Susanne Jaeggi, a professor with the Center for Cognitive and Brain Health at Northeastern University, says that the games being good for brains question isn't that simple.

“There are a lot of different things that contribute to our brain health," Jaeggi says. "As long as you’re doing something that keeps your brain engaged and fit, that could potentially be helpful to prevent age-related cognitive decline. Whether it’s exactly these games, that’s an open question, because a lot of these are new and there’s not a lot of (research) out there.”

A big question people have is whether games can help ward off age-related cognitive issues and dementia diseases. While Alberts says there’s no evidence for brain games preventing or delaying the onset of dementia, certain games do utilize cognitive functions that tend to diminish with age. “Fluid functions” like problem-solving, processing speed, and working memory tend to wane as we age, and some of the NTY Games puzzles force your brain to perform those functions.

A study published in NEJM EvidenceNEJM Evidence found some evidence that crossword puzzles can have a positive impact on aging brains. The study found that people age 62 to 80 with mild memory problems who played web-based crossword puzzles showed improved cognition and less brain shrinkage than to those who played web-based cognitive games.

However, crossword puzzles largely draw on things we already know, which is different than making our brains do something new or solve problems. “All your knowledge that you accumulate as a result of expertise and education, these are skills that remain as we age,” Jaeggi said. “Things like crossword puzzles that have you retrieve this accumulated knowledge, that’s not typically something that declines with age.”

One way to keep our brains sharp as we age is to try new things, and games can be a part of that. “What seems to be the case is that if you learn new skills and they’re challenging at whatever level of challenge is appropriate for you, then you see benefits,” said Art Kramer, psychology professor and director for Northeastern University's Center for Cognitive and Brain Health. “So if you’ve never done crossword puzzles or you’ve never played (Sudoku), that might be of benefit to you.”

Novel and enjoyable seem to be the key, so if games are your thing and you want to reap the benefits, enjoy the puzzles you love but also try some new ones once in a while.

Boost your Brain: Lifestyle changes that enhance cognitive function in adults

Unlock the secrets to sharper thinking with simple lifestyle tweaks.

Photo by Marisa Howenstine on Unsplash

men's white crew-neck T-shirt

Do you often walk into a room and forget why you are there? Or when you sit down to read a book, do you end up reading the same paragraph over and over? If you experience these things frequently, you may be worried that your cognitive function is declining.

The brain structure changes and shrinks as we get older, which can result in minor cognitive decline. However, frequent disorientation, forgetfulness, and difficulty making decisions can be signs of serious cognitive impairment—such as dementia or Alzheimer’s disease—that significantly interferes with daily activities and reduces quality of life.

Fortunately, there are some measures you can take and lifestyle changes you can make to potentially improve cognitive function. Many factors contribute to Alzheimer’s disease and dementia risk, and these measures are by no means a guarantee that you won’t develop these conditions. However, they may help protect the brain from age-related cognitive decline by boosting brain connectivity and enhancing cognitive processes.

What are cognitive functions?

Cognitive function is an umbrella term that encompasses various brain activities, ranging from simple to complex. In other words, cognitive functions are the mental processes through which your brain communicates with your body to perform tasks. Some examples of cognitive functions include language abilities, reasoning, problem-solving, planning, decision-making, learning, attention, verbal fluency, knowledge acquisition, and information manipulation.

Types of cognitive impairment

Cognitive functions tend to naturally decline with age, making it difficult to distinguish normal, age-related changes in cognitive functioning from the early stages of disease-associated cognitive decline. For instance, memory difficulty, which is common in older individuals, is also a common symptom of dementia and Alzheimer's Disease.

Contrary to common misconceptions, not all forms of cognitive decline involve memory problems or difficulty thinking clearly. Some cognitive disorders initially present with sleep problems, behavioral or personality changes, such as poor judgment and impulsivity, or difficulty with environmental interactions.

Furthermore, depending on the cause, cognitive impairment may be temporary or progressive. For example, delirium, a mental state characterized by confusion and disorientation, is temporary, whereas all forms of dementia (including Alzheimer’s Disease) are progressive.

Age-related cognitive decline

Slight cognitive decline and some changes in cognitive performance are normal parts of aging. Most cognitive functions peak around age 30 and subtly decline with advancing age. Age-related cognitive impairments include difficulties with multitasking, retaining information, word-finding, and maintaining attention, as well as an overall decline in thinking and perceptual speed.

It is worth mentioning that not all cognitive abilities decline with age. For many, verbal reasoning, vocabulary, and other aspects of crystallized intelligence remain unchanged or improve with age.

Mild cognitive impairment

Mild cognitive impairment (MCI) refers to impairments in cognitive functioning, such as memory loss, that are more severe than in other people of the same age. While these changes in cognitive function are noticeable, they are not severe enough to qualify for a dementia or Alzheimer’s disease diagnosis, and they do not interfere with daily cognitive functioning.

Mild cognitive impairment can have various causes, including:

Nutritional deficiencies
Depression, anxiety, or other mental health conditions
Thyroid conditions
Autoimmune disorders
Not getting enough sleep
Infections
Medication side effects
Early stages of dementia

The cause of cognitive decline often determines the extent of compromised cognitive function in the individual and whether they can expect to suffer progressive cognitive decline. For those whose condition is not progressive, the symptoms of cognitive decline may slow or reverse, and many may return to their previous cognitive abilities.

However, for other individuals, cognitive decline may worsen over time and possibly progress to dementia or Alzheimer’s disease, diseases that significantly impair cognitive functioning.

Generally, individuals with mild cognitive impairment have an increased dementia risk, but mild cognitive impairment is not a guarantee of a future dementia diagnosis. Studies examining the risk factors for the progression of MCI to dementia indicate the risk of developing Alzheimer’s disease or dementia is three to five times higher for individuals diagnosed with MCI than for those with normal cognitive function.

Dementia

Dementia is characterized by a loss of behavioral and cognitive abilities that significantly interferes with a person's ability to perform daily tasks, resulting in a reduction in quality of life. The signs and symptoms of dementia typically present when healthy neurons stop working, lose connections, and die. Some neuron loss with age is normal; however, those with dementia experience a much greater loss of cognitive functions.

The signs and symptoms of dementia vary by individual, but typically include:

Memory loss and confusion
Sleep problems
Difficulty with fine and gross motor skills
Decline in executive functions (e.g., working memory, planning, emotional control, etc.)
Difficulty understanding and expressing thoughts
Problems reading and writing
Reduction in psychomotor speed
Repetitive questioning
Changes in diet and eating habits
Poor judgment and acting impulsively
Disorientation in familiar places
Taking longer to complete everyday tasks
Losing interest in daily activities
Hallucinating, delusions, and paranoia
Balance and mobility problems

There are several types of dementia, and all are progressive. The most common forms are Alzheimer's disease, in which abnormal protein plaques accumulate in the brain, Lewy-Body dementia, and vascular dementia, which results from blocked or leaky arteries in the brain. Although the underlying cause of dementia disease varies, the effect is the same—reduced cognitive abilities and cognitive impairment.

How to improve cognitive function

The brain shrinks as we age, and the number of synapses and neurotransmitter receptors—both allowing neurons to communicate with each other—decreases. These brain changes can cause minor cognitive impairment, particularly in memory, attention, processing speed, and planning. However, many lifestyle factors affect cognitive function, and changing your routine can help slow age-related cognitive decline.

Regular physical activity

Research shows that physical activity can have a beneficial effect on cognitive function in all age groups. Exercise increases blood flow to the brain and neurotrophins, including brain-derived neurotrophic factor (BDNF), which promotes neuron growth, repairs brain cells, and helps the brain develop new connections.

Exercise can also increase the volume of the hippocampus, a part of the brain responsible for forming new memories. Additionally, aerobic exercise is thought to be a factor in minimizing the risk of dementia and other neurological disorders, including Alzheimer’s disease.

Brain training

Brain training involves regularly engaging in cognitively stimulating activities and exercises challenging information processing and cognitive abilities. Examples include crossword and sudoku puzzles, jigsaws, problem-solving activities, reading and writing, and learning new skills and hobbies.

Memory training is a type of brain training designed to improve episodic memory—remembering events that occur in daily life—and working memory, a type of short-term memory essential to information manipulation. Memory training activities include puzzles, matching games, and word games that involve trying to remember as many words as possible in a given time.

Challenging the brain is known to build up cognitive reserves, aka the brain’s flexibility and agility. This can potentially reduce susceptibility to age-related changes in the brain and decline in cognitive functioning. As such, brain training can also lower the risk of developing Alzheimer's disease, dementia, and cognitive dysfunction. There’s a plus – regular brain training activities in one sphere can help improve your cognitive abilities in other areas, which, in turn, can preserve your overall cognitive ability.

Stay social

Humans are social animals. Positive social interactions can improve one’s quality of life and the ability to relate to others. People who are isolated may see a degradation of their cognitive ability sooner than those who stay engaged with others.

While research into social interactions and cognitive function is limited, a few trials have yielded positive results, indicating that positive social engagement can increase hippocampal volume and improve memory and overall brain health.

Sufficient rest

Sleep patterns change as we age, with sleep interruptions and early waking becoming increasingly common. Not getting enough sleep can negatively affect attention, memory, and executive functions (higher-level cognitive skills like flexible thinking and self-control).

Lifestyle changes can improve sleep patterns, which can support cognitive function. These include spending more time in the sunlight, maintaining a consistent sleep routine, taking short afternoon naps to counteract nighttime sleep loss, and seeking treatment for sleep problems and disorders like sleep apnea and insomnia.

Foods that can boost cognitive function

Research indicates certain foods can enhance cognitive abilities, protect the brain from damage, and slow cognitive decline. However, the mechanisms by which these foods impact cognitive functioning are unclear.

However, existing research indicates that certain nutrient components can reduce inflammation, oxidative damage, and the buildup of toxic proteins in the brain. These nutrient components may also promote the formation of new synapses and brain cells, prolong the life of existing brain cells, and support the lining of blood vessels, increasing the blood supply and oxygen to the brain.

Some of the best “brain foods” include:

Berries

Berries are rich in flavonoids and pelargonidin—natural plant pigments associated with enhanced memory, improved cognitive function, and a reduced risk of dementia and Alzheimer’s disease.

Green leafy vegetables

Green leafy vegetables are rich in brain-boosting nutrients like folate, beta carotene, vitamin K, and lutein. They can help slow cognitive decline and lower the risk of developing Alzheimer’s disease.

Oily fish

Fatty and oily fishes, like tuna and salmon, are rich in omega-4 fatty acids, which can lower levels of beta-amyloid—a protein that accumulates in the brains of patients with Alzheimer's disease—in the blood.

Legumes

Soybeans, black beans, kidney beans, and chickpeas have high concentrations of anti-inflammatory compounds that can support overall brain health and boost cognitive functioning.

Whole grains

Whole grains are an excellent source of phytonutrients, B vitamins, and antioxidants. They can significantly benefit brain function and lower the risk of dementia and Alzheimer’s disease.

Tumeric

This well-loved spice contains curcumin, a compound that may increase BDNF levels, lower the risk of dementia and Alzheimer’s disease, improve cognitive abilities, and support overall brain health.

Other brain-boosting Foods

Other foods that can improve cognitive function and mitigate cognitive decline include monounsaturated fatty acids, nuts, green tea, dark chocolate, and coffee. Some nutritional supplements, especially those containing vitamins D and B12, can also help support brain health and lower the risk of Alzheimer’s disease.

Conclusion

Cognitive abilities tend to decline as we get older, with many people experiencing subtle changes in cognitive function by or before middle age. However, if these age-related changes are more severe or frequently occurring than those of other individuals in the same age group, they may be signs of mild cognitive impairment.

While mild cognitive impairment does not always progress to dementia or Alzheimer’s disease, those with MCI are more likely to develop dementia and other conditions involving significant cognitive decline.

Some lifestyle factors can impact cognitive function and play a role in the likelihood of developing dementia, Alzheimer’s disease, and similar conditions. Positive lifestyle changes like brain and memory training, regularly exercising, sleeping well, engaging in social activities, and eating a healthy diet with plenty of “brain foods” can support overall brain health and improve cognitive function. As such, incorporating these lifestyle changes into daily life may help slow age-related cognitive decline, improve cognitive performance, and lower the risk of dementia and Alzheimer’s disease.

Nature does wonders for your brain. Here's how to escape if you're stuck in a city.

When I sit on a pillow on my bedroom floor to meditate, the first thing I notice isn’t my breath, or a sense of peace, or my inner voice — it's the sound of cars zooming past my window.

Normally I can tune out the noises of the city. I have to. I live in the middle of an urban area, so at all moments of the day, I can close my eyes and listen to cars honking, brakes squealing, and airplanes flying overhead.

No matter how long I’ve called cities my home, the urban din still induces anxiety in me. It’s a claustrophobic reminder that I’m surrounded on all sides by concrete, cars, and buildings.

Sometimes, I need an escape.

Lately, I’ve been finding that escape in small pockets of nature: the veins of green space that run through my city, the elements of the natural world that persist amid the concrete, and the sights and sounds of living things that are often drowned out by city life.

Learning how to connect to nature while in a dense urban area has worked wonders on my mental health, and it probably could help your head, too: There’s tons of research on how nature is medicine for the soul.

Here are a few of my strategies for connecting to the natural world when you live in a city.

1. Take advantage of green spaces inside the city.

Your city probably has more public parks than you realize. The next time you have a free Saturday afternoon, check out your city’s Parks and Recreation website instead of binge-watching the third season of "Parks and Recreation" on Netflix (no shame, I do it too). If you really want to put some distance between yourself and urban life, check out a nature preserve or find a trail that leads away from busy roads. If you’re feeling more social, see if your city’s Parks department has volunteer days, so you can explore a green space while meeting friends.

2. Think smaller.

Sometimes, you can’t disappear into a peaceful island inside the city, but you can still find some peace in the outdoors wherever you go.

A 2017 study from the University of British Columbia looked at the effects of connecting with nature on a smaller scale: noticing a flower, watering a houseplant, watching the sunset. Researchers found that even these seemingly minor encounters made people feel happier and more connected.

So the next time you’re feeling stressed or upset, take a walk to visit your favorite tree. It may seem silly at first, but it works.

3. Get out of town.

I know, I know — this isn’t always an option, especially if your transportation options are limited. But if you can rent a car or take a bus out to some nearby campgrounds or a state or national park, you should do it.

Spending time immersed in nature can literally change the way your brain functions. If you can find a spot without cell service, even better.

4. Spend more time noticing.

When you walk to the subway station, how many types of trees do you pass? The birds you hear outside your window — are they all the same species singing the same song, or is there variation?

You may not always have the time to physically escape the city to find nature, but you can take a few moments every day to let nature find you. No matter where you are, you can sit and listen and watch. You don’t have to be an expert birdwatcher or a trained biologist to engage in this exercise. But if you lean into your curious side, you will find yourself wanting to know more about the family of doves who live on your block, or how to distinguish between a sycamore tree and a maple. The more you discover about your non-human neighbors, the more connected you will feel to them. And that’s a relationship worth nurturing.

So get out there and find your peace in some nature! Sit quietly, observe, and listen to what the outdoors has to say.

Feel better after being outside? There’s a scientific reason for that.

Throwing shade at mental health. But, you know, the nice kind of shade.

True

As long as humans have been reading and writing, thinkers and researchers have been studying trees and their immense impact on our world.

We know they're powerful carbon sinks, sucking up carbon emissions and helping purify our air and limiting runaway climate change. We know their extensive root systems act like giant sponges, helping to sop up rainwater during storms and prevent erosion. At all stages of their life cycle, they provide habitats for other living things — from moss to lichen to insects to birds to delightful Disney-esque woodland creatures.

With all of the things trees do for the world, it's easy to wonder: What other ways do trees influence our lives? When people say they feel better after a long walk in the woods, is there a psychological, or even physiological, reason for that? According to scientists: yes. There really is.

The physical health benefits of trees are hard to deny.

A 2014 study in Environmental Pollution tried to quantify the health benefits of trees in America. Looking at data from 2010, they determined that each mature tree removes 17 metric tons of air pollution, and collectively, trees prevented 670,000 cases of respiratory problems like asthma and 850 human deaths. A 2015 study of residents in a Toronto neighborhood found that people who reported better health lived on streets with more than 10 trees. Researchers were able to equate those improved health perceptions with an income increase of $10,000 or a relative age of seven years younger.

Being around trees isn't necessarily the only way to reap their benefits — sometimes just having the ability to look at them can help.

A famous study of surgical patients recovering in a Pennsylvania hospital in the 1970s found that persons whose rooms overlooked trees recovered faster than those who didn't have that view. Japanese healers advocate for the health benefits of shinrin-yoku, ("forest bathing"), where people take long walks in the woods while inhaling complementary aromatherapy scents. A peer-reviewed study of shinrin-yoku found that it helped people lower levels of stress hormones and decrease their blood pressure, with benefits lasting up to one month.

Whatever it is that's going on in our brains at the time, it really seems that just being in the presence of trees can leave us happier and more content.

Maybe they remind us that life grows and goes on and flourishes in the toughest places. Maybe there’s something about leaves, about vibrant colors, about the smell of strong wood, or the way sunshine looks dappled through summer leaves. Psychologists believe there's truth to that idea. They call spending time in nature attention restoration theory, or ART. The theory behind it is that natural environments demand so much less of our attention than cities do and that being in nature allows our brains time to rest.

Whatever it is about trees that improves our mental health, it’s powerful and potentially transformative. Even city planners are taking notice.

In the past decade, major cities, including Barcelona, New York, and Vancouver, have made increasing green spaces and their urban canopy a big priority. For Vancouver, this includes planting lots of new trees, legislating protections for older trees, protecting parklands, and encouraging residents to spend time outside.

Chances are, though, that you're not reading this while you're outside. Maybe you can't even get outside right now. In that case, maybe a few minutes spent looking at photographs of particularly lovely trees can give us some of the same calm, fuzzy feelings? Let's try!

Hal Borland famously said, "If you would know strength and patience, welcome the company of trees."

He's right, of course. Though we'd also add in "peace of mind" too.
