Man unexpectedly dies during brain scan. What scientists saw should give everyone comfort.

They may have uncovered the secrets of our final moments.

A doctor is analyzing brain scans.

Death remains one of the greatest mysteries of life. It’s impossible to know what happens as a person passes and whether there’s anything afterward because no one has ever been able to report what happens from beyond the grave. Of course, if you ask those with a keen interest in the supernatural, they may say otherwise.

However, in 2021, researcher Dr. Raul Vicente and his colleagues at the University of Tartu, Estonia, became the first people ever to record the brainwaves of someone in the process of dying, and what they’ve come to realize should be very comforting to everyone. “We measured 900 seconds of brain activity around the time of death and set a specific focus to investigate what happened in the 30 seconds before and after the heart stopped beating,” Dr. Ajmal Zemmar, a neurosurgeon at the University of Louisville, US, who organized the study, told Frontiers.

The patient who died while having his brain waves measured was 87 years old and had epilepsy. While researchers were studying his brain to learn more about the condition, the man had a heart attack and passed away. “Just before and after the heart stopped working, we saw changes in a specific band of neural oscillations, so-called gamma oscillations, but also in others such as delta, theta, alpha, and beta oscillations,” Zemmar said.

The different types of brain oscillations that occurred in the patient before and after the heart attack were associated with high cognitive functions, including dreaming, concentrating, memory retrieval, and memory flashbacks. Therefore, it’s possible that as the patient was dying, they had their life flash before their eyes. What an amazing and comforting experience right before leaving this mortal coil.

“Through generating oscillations involved in memory retrieval, the brain may be playing a last recall of important life events just before we die, similar to the ones reported in near-death experiences,” Zemmar speculated. “These findings challenge our understanding of when exactly life ends and generate important subsequent questions, such as those related to the timing of organ donation.”

How long are people conscious after they are technically dead?

Science has found that people can remain conscious up to 20 seconds after they are declared dead. Even after the heart and breathing have stopped, the cerebral cortex can hang on for a little while without oxygen. So, some people may experience the moment when they hear themselves declared dead, but they aren’t able to move or react to the news. In cases where someone performs CPR on the deceased person, the blood pumped by the compressions can temporarily keep the brain alive as well.

Although the experience of death will probably always remain a mystery, we should take solace in the idea that, in many cases, it may not necessarily be a miserable experience but an ecstatic final burst of consciousness that welcomes us into the great beyond. “Something we may learn from this research is: although our loved ones have their eyes closed and are ready to leave us to rest, their brains may be replaying some of the nicest moments they experienced in their lives,” Zemmar concludes.

How often should you shower? Doctors weigh in and rock some people's worlds.

Once a day is not ideal.

Doctors say a lot of us are showering more than we need to.

A few times in recent years, celebrities and social media influencers alike have made waves by sharing that they don't make their kids bathe every day. For some parents, that was totally par for the course, but for others, letting a child go more than a day without bathing was seen as a travesty.

Doctors have made it clear that kids don't need to bathe daily, with some going so far as to recommend against it when they are young to protect kids' delicate skin. But what about grownups? Most of us don't take baths regularly as adults, but what's the ideal frequency for showering?

According to a YouGov poll of over 5,700 Americans, just over half of respondents said they shower daily and 11% said they shower twice or more per day. That means two out of three of us are showering at least once a day.

But according to doctors and dermatologists, that's probably overkill for most people. Unless you're doing heavy labor, exercising vigorously, working outdoors or around toxins or otherwise getting excessively dirty or sweaty, a few showers per week is enough for healthy hygiene.

In fact, Robert H. Shmerling, MD of Harvard Health says too frequent showering could actually have some negative effects on your health.

"Normal, healthy skin maintains a layer of oil and a balance of 'good' bacteria and other microorganisms," Dr. Shmerling writes. "Washing and scrubbing removes these, especially if the water is hot." He shares that removing that protective layer can make our skin dry, irritated or itchy, which can lead to damage that allows allergens and bacteria to cross the skin barrier. Additionally, our immune systems require exposure to microorganisms, dirt, and other environmental stimuli in order to create "immune memory," and if we wash them away too frequently, we might be inhibiting the effectiveness of our immune system.

Dermatologists who spoke to Vogue had similar advice about shower frequency. Board-certified dermatologist Deanne Robinson, MD, FAAD told the magazine that you can skip showering for the day if you haven't engaged in rigorous activity. Mamina Turegano, a triple board-certified dermatologist, internist and dermatopathologist. agreed. "I think that showering three to four times a week is plenty for most people,” she said.

Of course, everyone is different and what is good for one person's skin isn't good for another's. Showering frequency and health also depend on what kinds of products you're using, what temperature of water you're using, and how long your shower is. There's a big difference between a quick pits-and-privates rinse-off and a long, hot everything shower.

While scorching yourself and steaming up the bathroom may feel luxurious and relaxing, especially if you've got sore muscles, dermatologists say it's not good for your skin. Hot showers are especially problematic for people with skin issues like eczema.

"Any skin condition characterized by a defective skin barrier can be worsened by a hot shower," board-certified New York City dermatologist Shari Marchbein told Allure. "[It] strips the skin of sebum, the healthy fats and oils necessary for skin health, and dehydrates the skin."

In fact most dermatologists recommend keeping showers lukewarm. That sounds like torture, frankly, but who's going to argue with the experts?

A lot of people, actually. Modern humans are pretty particular about our shower preferences, and judging from the comments on cleanliness discussions, some folks are dead set on the idea that a daily shower is simply not negotiable. Even with the experts weighing in with their knowledge and science, a lot of people will continue to do what they do, advice be damned.

But at least the folks who've been judged harshly by the daily shower police have some official backup. As long as you're showering every couple of days, you're golden. As it turns out, there really is such a thing as being too clean.

Mama cat rushed her kittens to a human hospital. Doctors treated them as patients.

She knew just where to go for help.

A mama cat brought her kitten into the hospital to be treated for an eye infection.

A family of kittens in western Turkey has won people's hearts with an emergency visit to a hospital. Not an animal hospital—a human hospital. And it wasn't a pet owner who brought them in, but the mama cat herself. According to Gulf Today, staff had previously left food and water for the stray orange tabby outside the hospital in Izmer, Turkey, but that morning she kept meowing outside.

Finally, she fetched one of her kittens and carried it right into the hospital, clearly on a mission. She wasn't scared or shy as hospital personnel cleared the path for her. With her baby in her mouth, she trotted through the hallways, seemingly looking for someone to help. Medical personnel examined the kitten along with its siblings and consulted with a veterinary clinic.

As it turned out, the kittens had an eye infection. Mama kitty's maternal instincts are really something else. Just look at this sweetness caught on video:

According to the Daily Mail, one of the hospital workers told local media: "We were giving food and water to the mother cat living on the street with other people living in this area. However, we did not know that she gave birth to kittens. As we began to receive patients in the morning, she showed up with her kittens. She asked for help, meowing for a long time. We were shocked. Upon careful examination, we saw that the kittens were not able to open their eyes due to infection. We consulted with veterinarians and gave medicine as described. When the kittens opened their eyes a short time later, we were thrilled. Later, we sent the mother cat and kittens to Uzundere for further care. This is the first time something like this has happened to us. We were emotional and delighted to see that they recovered well."

This isn't the first time that a mama cat has made news for bringing her kittens into a hospital in Turkey, however. Last spring, a different cat brought her kitten into an emergency room at a hospital in Istanbul. Merve Özcan described the scene in Twitter posts that went viral at the time.

"Today we were in the hospital emergency, a cat rushed to the emergency with her baby she was carrying in her mouth," Özcan wrote. "Her baby is a little mischievous, her mother grabs it where she finds it." Mother cat carries her sick kitten into Turkish hospital and 'asks doctors for help' https://bit.ly/2QRQao3 #CatsOfTwitter #Turkey.

Medics examined the kittens for apparent signs of illness, while the mama cat was given milk and food. Then they were sent to a vet.

"The Turks have long been known for their love and care for stray animals," Bored Panda reported, "with many leaving out food and water for them on the streets."

No wonder these cats felt so comfortable bringing their kittens into human hospitals for help.

While we can't know for certain what prompted these mama kitties to bring their babies to these medical professionals, it's clear that their maternal instinct to protect and keep their kittens healthy is strong. And the fact that they seem to trust the hospital personnel to take care of their babies says a lot about how humans have treated them. Good for these Turkish medical workers for setting an inspiring example of kindness to animals.
