Have you ever wondered that hair is actually the fastest going tissue in the body after the bone marrow? As per the studies, if you buzz your hair off, it takes three years to grow to the shoulders and seven years to the waist.

Water also changes the hydrogen bonds in our hair, making it flatter after a shower. This could explain why some women dislike humidity: the water in the air changes the silkiness and structure of the hair, causing some hair to become frizzy or puffy.

With all that our brains have to deal with daily, it is understandable that they may want a well-deserved vacation from time to time. Blinking, thankfully, comes to the rescue around 15 to 20 times each minute. According to one research, that brief sleep period allows the brain to power down and take a mental break for a split second before resuming focus. As a result, experts believe that we blink more when performing a task that involves greater mental effort since our brain requires more rest the more we stress it.

The left hemisphere of the brain is said to control analytical and reasoning skills, while the right hemisphere controls artistic and creative thought. As a result, many people believe that creative writers are right-brain dominant. However, studies have revealed that this is not the case, and that many creative writers do not have a dominant hemisphere, but rather are more or less equally balanced between the two. Indeed, because both sides of the brain are always working together, there is very little evidence that there are truly dominant brain hemispheres.

Women, unlike males, require more sleep, according to Duke University researchers. It turns out that if women don't get enough sleep, their physical and mental capacities suffer more than men's. According to sleep researcher Michael Breus, women are more likely to go into depressed moods due to a lack of sleep, and they are more irritable in the morning.

If you suffer from chronic headaches and have tried everything to relieve the pain, love could be the secret solution you've been looking for. When researchers at Stanford University School of Medicine administered a nasal spray containing oxytocin, or the "love hormone," to subjects suffering from chronic headaches, they discovered that 50 percent of participants reported their headache pain was cut in half after four hours, with an additional 27 percent reporting no pain at all during the same timeframe.

Norwegian scientists conducted an experiment on college students, giving one set of students printed text sheets and asking the second group to read the same content on a computer screen in PDF format. It turns out that pupils retain knowledge better when it is printed on paper. It's yet another win for printed books versus digital gadgets.

Hair can tell everything about a person and hence is used by forensic experts. The hair can tell everything in a person's bloodstream, such as medicines, drugs, vitamins, minerals, and so on. The only thing that cannot be identified from the hair of a person is its gender. Isn't this interesting?

We can't completely comprehend the strength of our own vision since even on level terrain, we're constrained by the skyline. The maximum distance at which the experiment is unaffected by Earth's form is just approximately 3.1 miles. In truth, a person can see considerably farther: if the world were flat, we would be able to see a flame at a distance of 27 miles in absolute darkness.

For those who fantasise about being buried at sea, Eternal Reefs has devised a novel solution. It combines a person's cremated remains with concrete to form a "pearl" onto which loved ones can etch personal messages, handprints, or (eco-friendly) mementos. The pearl is then encased in a "reef ball" and dropped into the sea, where it provides a new habitat for fish and other sea life, promoting a healthy ecosystem. At work, the circle of life!

There are many things going on in our bodies over which we have no control. For example, most of us cannot control the size of our pupils unless we change the amount of light that enters our eyes. Researchers observed a man who can apparently change the size of his pupil on command in a study published in the International Journal of Psychophysiology in 2021. Currently, he is the only person known to be capable of doing so—though you could give it a shot if you wanted!

According to a recent study, people who read are two and a half times less likely to be diagnosed with Alzheimer's later in life. Although this does not imply that reading will prevent the disease, it does demonstrate a slight link between reading and prevention.

You've probably heard that the human body is primarily comprised of water (55 to 60 percent for adult women and men, respectively). You might be shocked to learn that fluid exists not just in your skin, muscles, and organs, but also in your skeleton. According to the US Geological Survey, water accounts for roughly one-third of your bone mass.

Let's use a mental image to put this into context. If each strand of your hair can support 100g, and most people have 100 000 to 150 000 strands of hair on their scalp, your entire head can support the weight of two elephants - wow!!

What do you mean? The chorda tympani joins the face nerves with the middle ear, and it is partly responsible for taste reception on the tip of your tongue! It turns out that experiencing a lot of inner-ear infections as a youngster might change your taste buds, making you favour energy-rich and fatty meals. A recent research even connected it to obesity!

At the very least, they may have a common ancestor. Danish researchers discovered that blue-eyed people from Scandinavia, Turkey, Jordan, and India all have same gene sequences for eye color after examining the DNA of blue-eyed people from those countries. They believe this characteristic originated with a single individual known as the "founder," whose DNA altered between 6,000 and 10,000 years ago. Previously, everyone had different hues of brown eyes.

You remember from elementary school that all humans are mostly made of water, but never more so than right after birth. According to NASA, newborn babies are 78 percent water, while adults are only 55 to 60 percent water.

Singing can actually get rid of stress. As singing has psychological benefits because it has a normally positive effect on stress levels via the endocrine system, which is linked to our sense of emotional well-being. “Psychological benefits are also evident when people sing together as well as alone because of the increased sense of community, belonging, and shared endeavour,” observes Professor Graham Welch, Chair of Music Education at the Institute of Education at the University of London.

According to research, many people who are not predisposed to becoming overweight perform “additional” motions over the course of their everyday lives, such as tapping their fingers, pacing in circles while chatting, and so on. Even this seemingly insignificant physical exercise aids the body in burning up to 350 additional calories each day. This implies that simply tapping your fingers can help you lose up to 30 pounds every year.

We are a part of the cosmos, and scientific study backs up this claim. Aside from hydrogen, which is big bang dust, all other elements in our bodies are made of stardust. After completing the math, this would imply that 97 percent of our bodies are made out of stardust.

We've all experienced the uplift and mood-altering effects that music can have on us, but its power doesn't end there. According to one research, a good song may physically speak to the heart. The heartbeat was discovered to synchronize with the musical rhythm. In fact, researchers discovered that crescendo choices caused a rise in blood pressure, pulse rate, and breathing. On the other hand, these measures decreased during decrescendos and quiet intervals.

People may try to convince you that long-distance relationships can't and won't work, but research shows otherwise. According to one study published in the Journal of Communication, long-distance relationships are not only as successful as regular ones, but they are also more effective in building trust and satisfaction between partners.

Please pass the deodorant: According to the International Hyperhidrosis Society, you have two to four million sweat glands all throughout your body. The majority of them are non-stinky and may be found on the soles of your feet, palms, forehead, and cheeks. Do you consider yourself to be the "sweaty" type?

Darwin proposed that pupils expand during periods of increased attention and focus as early as the 1870s. This is true, as it occurs when looking at a desired or beloved object, even if it is only a picture or a video. Furthermore, people with dilated pupils appear more attractive.
