Find out what happens to your body when you see someone you love (and more!)

Ever wonder what the science behind heartbreak is? Find the answer here.

Love doesn't have to be all about romance. It can also be about SCIENCE.

And who doesn't love some science? Let's take a look at some of the hard facts of the history and science of the heart.


Hahhhh. Get it? Limbic system = part of the brain.


FACT: By 2000 B.C., Chinese doctors had uncovered the heart's role in pumping blood throughout the body.


This diagram of the heart is from a medical book published in 1864.

Yep, they figured that ish out in 2000 B.C., as in 4,000 years before today. Also known as a ridiculously long time ago. Meanwhile (or rather, about 1,600 years later), Aristotle was busy hypothesizing that the heart was the center of intelligence. Even through the Renaissance, many great thinkers believed that the heart governed a person's emotions — "a notion so powerful that it still persists today in a different form."

FACT: Even though feelings of love come from our brain, we really can physically feel them.

Pretty cool, huh? Let's take a look at both sides of this coin.

The "happy side" of feeling love is that when you see a loved one, your brain stimulates the release of neurotransmitters that make you feel real good. Epinephrine and norepinephrine are secreted from your adrenal glands, which cause your heart to beat faster.


Yay!

Of course, those aren't the only neurotransmitters involved in love. There are SO many chemicals and hormones at play — dopamine, serotonin, oxytocin, vasopressin ... on and on. They all work together to govern sex drive, partner preference, and attachment. It's complicated science, but the bottom line is simple: When you're in love, your body reacts big time. It's far from "all in your head."


Slightly cute, mostly creepy. For more info on other chemicals involved in love, check out this video.

The "heartbroken side" of feeling love is that emotional loss activates the same region of your brain as physical pain. This can lead to great levels of neurological stress, which can actually overstimulate your vagus nerve, causing nausea, dizziness, and physical pain. That's heartbreak.


And that's why you can actually feel a broken heart.

FACT: Many animals average 1 billion heartbeats in their lifetime, no matter their size or life span.

The billion beat hypothesis says that an animal's heart will beat around 1 billion times, no matter their size or life span. Smaller animals have shorter life spans and faster heart rates whereas larger animals have longer life spans and slower heart rates.


That's heart beats per minute, life span in years, and lifetime heartbeats in billions.

Small animals have a larger ratio of surface area to mass, so they lose heat more quickly and have higher metabolic rates — which are linked to shorter life spans. As mass goes up, so do life spans while heart rates go down.


Is this all just a complicated way of saying that mice don't live very long? Maybe so.

But HUMANS defy the billion beat hypothesis. We live three times as long as we should with about twice as many heartbeats as we should be "allotted." Why? Because modern science and medicine have extended our life span. It's pretty corny, but ...

Caring for one another helps humans defy the principles of science.

Awwww. Want to catch the whole video, with even more facts about loooooooove? Here it is:

ACUVUE launches a new campaign to inspire Gen Z to put down their phones and follow their vision

What will you create on your social media break? Share it at #MyVisionMySight.

True

If you’ve always lived in a world with social media, it can be tough to truly understand how it affects your life. One of the best ways to grasp its impact is to take a break to see what life is like without being tethered to your phone and distracted by a constant stream of notifications.

Knowing when to disconnect is becoming increasingly important as younger people are becoming aware of the adverse effects screen time can have on their eyes. According to Eyesafe Nielsen, adults are now spending 13-plus hours a day on their digital devices, a 35% increase from 2019.1. Many of us now spend more time staring at screens on a given day than we do sleeping which can impact our eye health.

Normally, you blink around 15 times per minute, however, focusing your eyes on computer screens or other digital displays have been shown to reduce your blink rate by up to 60%.2 Reduced blinking can destabilize your eyes’ tear film, causing dry, tired eyes and blurred vision.3

Karlie Smith shows the meal she's bringing to the restaurant for her son.

A mom who admitted she packs her 2-year-old a meal when they go out to dinner has started an interesting debate on TikTok about restaurant etiquette and how it applies to young children.

The video posted by Ohio mom, Karlie Smith (unbreakablemomma on TikTok), has received nearly 600,000 views and has over 1,850 comments.

“Call me cheap, call me whatever, but if we’re going out to a restaurant, I’m packing my kid a meal," Smith, 21, said in her post. "I do this for many reasons. On Friday nights, my family and I get together, and tonight, we’re getting food out. My son is not getting food out.”

Man rewatches shows from his childhood and his recaps of the bonkers storylines are priceless

Rob Anderson's hilarious recaps of shows like "Mighty Ducks," "Beethoven," and "7th Heaven" might make you wonder how they got made in the first place.

@hearthrobert/TikTok

These plots makes zero sense.

While there are no doubt some timeless classics from our childhood that remain every bit as amazing as we remember, many are straight-up cringey upon a later viewing. Really, it’s to be expected as societal viewpoints change…sort of a marker of how far we’ve collectively come.

And so, what do we do with these problematic pieces of old-school pop culture? Well, we can certainly update them to better reflect a more modern attitude, but that also comes with a set of potential problems. Or we could simply never watch them again. Certainly an option given all the content out there. But then we might miss an opportunity to better understand what seemed to work for the mainstream then, and why it doesn’t work now.

And then there’s the third option—allow ourselves to be entertained by their cringiness.

That’s certainly the route taken by Rob Anderson. Over on TikTok, Anderson has taken ultra-popular movies and television shows from his childhood and given them hilarious recaps capturing how absurd some of the storylines are.

Some moments never get old.

On November 19, 1999, a man named John Carpenter made game show history and quite possibly gave us all the greatest game show moment of all time.

Carpenter was a contestant on the very first season of “Who Wants to be a Millionaire” shot in America. Hosted by the late Regis Philbin, the quiz show featured three "lifeline" options to help them with difficult questions, the most popular being able to “Phone-a-Friend.”

Carpenter had impressively not used a single lifeline for any of his questions. That is, until question 15. The million-dollar question, to be exact.

Woman decides that she is the love of her life and marries herself at her retirement home

“I said, you know what, I’ve done everything else. Why not?”

77-year-old woman decides she's the love of her life and marries herself.

We joke about marrying ourselves or a platonic friend if some arbitrary amount of time has passed without a proposal from an imaginary suitor. And sure, some people do wind up marrying a friend in more of a business arrangement, but it's not very common that someone follows through with marrying themselves.

Dorothy "Dottie" Fideli, decided that she was going to break the mold. The 77-year-old sat down and thought about all of the things she had done in life and who was with her the entire time cheering her on. It was an easy answer: herself. She was her biggest cheerleader, the person who always showed up and the love of her life, so Fideli made the plan to marry herself.

On a beautiful May day, friends and family gathered in the O’Bannon Terrace Retirement Community, where Fideli is a resident, to witness the ceremony.

12-year-old Texas girl saves her family from carbon monoxide poisoning

She knew something was wrong with her mom and brother, which wound up saving her whole family.

Fort Worth 12-year-old helps save family from carbon monoxide poisoning.

Carbon monoxide is called a silent killer for a reason. Many people don't realize they're experiencing carbon monoxide poisoning before it's too late. The gas is colorless and odorless and tends to have a sedating effect that causes people to sleep through the fatal poisoning. Having carbon monoxide detectors is one of the most effective ways to identify the gas before it's too late to get out of the house, but not every home has one.

A little girl in Fort Worth, Texas, experienced a terrifying encounter with the deadly gas, but her quick actions saved her entire family. Jaziyah Parker is being held up as a hero after she realized something was wrong with her family members and called for help.

The girl called 911 after she noticed her mom pass out. On the call with the dispatcher, Jaziyah says she thinks her mother has died before explaining that there was something now wrong with her baby brother, who was just 5-months-old.
