There are a number of myths about the human body that has been around for a while and separating the facts from the lies is a tough task. Nonetheless, you may be pleasantly surprised at some of the weird things you have heard about the human body that are actually true.
Old People Have A Peculiar Smell
Asides old people, there is also a distinctive smell that comes from middle-aged people and young people. A recent research found that older people have a less intense and more pleasant—scent than the middle-aged folk and young fellas.
Waking Up At Night To Urinate only
The neurons in your gut that control colon contractions, which push out waste, are also influenced by your body’s circadian rhythm, the internal clock that wakes you up and makes you feel sleepy at night.
On the other hand, the bladder, which acts a reservoir for the continuous flow of urine produced in the kidneys, can stretch only up to a certain volume before you need to expel it’s content. You can sleep six to eight hours without having to urinate, but certain medical conditions or drinking too much water before bed can wake you to use the bathroom at night.
A lot of experts believe that fingerprints exist to improve grip but a British study has an entirely different idea. The researchers found that a fingerprint’s ridges actually made it harder to hold flat, smooth surfaces, like Plexiglas, because they reduced the skin’s contact area.
Instead, they think fingerprints might help wick water off our fingertips or allow our skin to stretch more easily, which can protect it from damage and help prevent blisters.
Some other scientists have suggested fingerprints could improve our sense of touch. One truth in it all is that no two people’s fingerprints are the same, even among identical twins.
Your Feet Grow Bigger With Age
After years of wear and tear, tendons and ligaments in your feet may weaken, and this can cause arches to flatten, which means your feet get wider and longer.
The fact however is that not everyone will experience it but people who are overweight, who get swollen feet or ankles, or who have certain medical conditions, such as diabetes, are more prone. If it does happen, the average gain is about one shoe size by age 70 or 80.
Women Get Colder Than Men
Women naturally have a higher percentage of body fat and conserve more heat around the core to help keep their vital organs warm. This however isn’t the case with their extremities. When women experience cold hands and feet, the rest of the body does same.
More so, research suggests that women have a lower threshold for cold than men. When exposed to the same freezing temperature, the blood vessels in women’s fingers constrict more than men’s do, which is why they turn white more quickly.
Joint Aches Can Forecast The Weather
A change in barometric readings may be part of the reason why weather can predict our health. Atmospheric pressure often drops right before bad weather begins and this shift could cause body tissue to expand, which can lead to swelling and pain.
The effect of this is slight, but people who have arthritic or inflamed joints may detect the difference. Researchers at Tufts University in 2007 also found that every ten-degree drop in temperature corresponded with a small increase in osteoarthritic knee pain.
