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!

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.

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.

The fear of falling asleep is known as somnophobia. Oneirophobia is the fear of having nightmares or having dreams. Clinomania is the irresistible desire to stay in bed all day, whereas dysania is the sensation of waking up and not wanting to get out of bed.

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?

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.

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.

It's very likely that you have eyelash mites, depending on your age. These microscopic organisms feed on dead skin cells and the natural oil (sebum) produced by human hair follicles. They are usually harmless, though a small percentage of people may develop an allergic reaction to them. Eyelash mites typically grow to a third of a millimetre in length and are nearly transparent, making them difficult to see with the naked eye. However, if you examine an eyelash or brow hair under a microscope, you may find them, as they spend the majority of their time at the base of the hair, where it meets the skin. They are present in approximately half of the population, with the proportion increasing with age.

Friendship is important for everyone, but it is especially important for women. According to a 2012 study at University College London's Department of Epidemiology and Public Health, family bonds are more important for men. Scientists studied 6,500 British men born in 1958 and discovered that marriage is the best thing for men's mental health because it strengthens their family ties. Women, on the other hand, tended to lose friends due to a lack of time when married. Female friendships can have a significant impact on the type of person these women are and will become. They also assist them in dealing with stress.

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.

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.

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!

Have you ever thought that a tongue can have 2,000 to 4,000 taste buds? But it does have! The sensory cells are responsible for how a person perceives taste. Moreover, about one-quarter population is believed to have the best sense of taste and are called 'supertasters.' Another quarter is considered 'non-tasters,' who can taste foods but are less sensitive and cannot detect the bitter taste PROP.

Adults who read on a regular basis are more likely to participate in charity and volunteer work, accroding to the studies. Perhaps the slogan "Make love not war"must be replaced with "Read fiction, not media". Although media is frequently fiction, it can be perplexing.

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!!

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.

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.

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.

Don’t worry if you accidentally swallow a razor blade. The human body is far more competent than you may believe. Acids are graded on a range of 0 to 14; the lower the pH, the stronger the acid. The pH of human stomach acid is 1.0 to 2.0, showing that it is powerful. Scientists discovered that the “thickened back of a single-edged blade” disintegrated after two hours of immersion in stomach acid in research.

Nobody compares to women when it comes to expressing oneself. It turns out that this phenomenon has an anatomical explanation: women have bigger frontal and temporal regions of the cortex, a brain region considered to impact language abilities. Women also have more FOXP2, often known as the "language protein." This high protein intake allows the average woman to say 20,000 words per day, 13,000 more than the average guy.

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.

Many psychological and social studies indicate that there is a significant pattern in how people choose people with whom to form romantic relationships. This pattern is explained by the Matching Hypothesis, which states that people are more attracted to those with whom they share a level of attractiveness, or who are equally socially desirable. Even if successful couples differ in physical attractiveness, one of them usually compensates for it with other socially desirable qualities.

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!

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.
