The world is a big, wonderful place full of facts we never thought possible. For instance, if a pregnant mouse has a sudden medical issue, the fetus will send stem cells to heal the mother, increasing its chances of survival as well. Fetal stem cells have been found in human mothers as well, dubbed by science as microchimerism.
Bright Side dug up some more marvelous facts about nature and its creations, upholding our yearly resolutions to spread knowledge and joy.
1. The heart slows when your face touches water.

As mammals, we can’t breathe underwater, so as part of the mammalian dive reflex, our heart rate goes down in the water — more so if we go underwater. Even splashing the face with water makes the heart slow down, making it a great way to calm down.
2. Fungus can break down plastic in weeks.

It is said that in the future, there may be more plastic in the ocean than fish. This is why the plastic-eating fungus is great news, and there are around 50 new species of such fungi discovered already. One of the fungi discovered can digest plastic within 2 months, so there’s hope for us yet.
3. Newborn babies can support their own weight.

Newborn babies are strong — strong enough to be able to grasp things in their tiny fists and even support their weight as shown by an experiment done in the nineteenth century. Louis Robinson witnessed babies able to hang from a walking stick, from 10 seconds to 2 minutes and 35 seconds.
4. Koala fingerprints have been mistaken for human ones.

We’ve been told that our fingerprints are unique, and they are. But the fact remains that even though we share a common ancestor with the koala that was alive 100 million years ago, koala fingerprints look very similar to human fingerprints, as do chimpanzee fingerprints for that matter.
5. Snails can sleep for 3 years.

If you thought bears had it good with hibernation, meet the snail. Snails can sleep rather than hibernate for 3 years at a time without needing food. Of course, this is with some snail species, not all of them. Meanwhile, bears usually hibernate for just 4-8 months.
6. Sloths need 2 weeks to digest food.

Sloths don’t only move in slow motion — even their insides move slowly, ostensibly to preserve energy, which is why a sloth’s digestive system takes 2 weeks to process the food it ate. Plus, most of what it eats is indigestible, giving it very little energy from each slowly chewed mouthful.
On the other end of the spectrum lies the shrew, whose digestion takes mere minutes and is done so fast, not much of it is fully digested. This is the reason why shrews eat their own feces. They can die of starvation in a matter of hours if they don’t eat.
7. Your brain ignores seeing your nose.

We can see our nose all the time, it’s just that the brain tends to ignore it because it’s a constant visual stimulus. It’s the same with people who wear glasses. After a while, they simply stop noticing them.
8. Your forearm is the same length as your foot.

If you don’t have the time to try on a shoe, measure it from your elbow crease to your wrist. If it fits or is just a little smaller, it would fit your foot because the length of your forearm is the same as your foot. And this is just one of many human body ratios that are a marvel in themselves, including the fact that your femur bone is one-quarter your height.
9. You can “see” your white blood cells.

If you look up at a cloudless, bright blue sky and see some wiggly things at the periphery of your vision, you’ve just experienced the blue field entoptic phenomenon. The wiggly things are white blood cells moving in the fine blood vessels moving in front of the retina, at the back of the eye.
10. Human beings have striped skin, but only cats can see it.

Human beings have stripes and patterns on the skin too, and they are called Lines of Blaschko, name eponymously by the scientist who discovered them, Dr. Alfred Blaschko. These are closer to tiger stripes, forming more of a V-pattern fanning out from the center to the extremities. These lines are visible under UV light, a spectrum that cats can see too, which is why cats can see you as a striped being as well.

Why Were Olympic Athletes & Other Celebs Spotted with Dark Red Circles on Their Bodies?

This year’s Olympics are now in full swing and it’s all eyes on the athletes.
From archery and shooting to athletics and gymnastics, there’s all kind of sports taking place across Paris, France, at the moment.
One fan-favorite sport to watch is the swimming, and this year there’s a whopping 854 athletes from 187 different countries competing.
But there’s a common theme you might have spotted with some of the swimmers and that’s the unusual dark red circles they have on their backs.

While it might look like they’ve had a fight with an octopus and lost, there’s a very different reason for the odd markings.
It turns out that the large spots are from cupping therapy – an ancient healing technique that involves placing cups on the skin to create suction and increase blood flow to the area.
The unconventional method is supposed to help with muscle recovery and is used as a type of deep tissue massage.
Some athletes were spotted with cupping therapy bruises back at the Rio Olympics in 2016, and it’s still seemingly popular now.

Gymnast Alexander Naddour told USA Today back in 2016 that cupping was supposedly the ‘secret’ to his health.
He added: “It’s been better than any money I’ve spent on anything else.”
Away from the Games, basketball player Kyle Singler has also praised cupping therapy.
“The bruises do look more intense than what they actually feel like, but the benefit from it is really great,” he previously insisted.
Singler continued to tell Sports Illustrated: “You’re not necessarily getting the immediate response that you might want but over time it does help with recovery and loosening tissue and stuff like that.”
But does cupping therapy actually work according to experts? It’s seems as if the jury’s still out.

According to Harvard Health, some studies have found that cupping might provide some relief for a number of musculoskeletal and sports-related conditions. The quality of this evidence was ‘limited’, however.
Elsewhere a 2022 review found that wet (as opposed to dry cupping) was effective for lower back pain.
While the bruises people get from cupping are pretty gnarly, the therapy is generally seen as safe to practice – even if people aren’t 100 percent on how affective it is.
“Most experts agree that cupping is safe. As long as those treated don’t mind the circular discolorations (which fade over a number of days or weeks), side effects tend to be limited to the pinch experienced during skin suction,” Harvard Health explains.
“It’s quite unusual that cupping causes any serious problems (though, rarely, skin infections have been reported).”
There you have it, folks.
