Our body has many mysterious ways of reactions- and some of the things that it does- may lead us to embarrassment, but they are good for the body- don’t believe us? Read below!
Goosebumps:
The funny little pimples we get when we’re cold, heat us up as quickly as possible, Goose bumps are caused by muscles contracting, allowing hairier people to retain more heat.
Itching:
This mystery is the equivalent to a cat’s whisker. Nerves in the skin send signals to the brain ringing alarm bells that something is not quite right. The urgent desire that the brain makes to make it go away leads to our scratching.
Blushing:
Blushing has evolved as a product of the communication and social interaction with other human beings. It signals to others that we are upset or embarrassed
Adrenaline rush:
There was a time when most people would have felt the rush of adrenaline through their bodies at the howl of a wolf pack. This is nature’s high octane method of keeping us alive in threatening situations The term fight or flight was first coined in 1932 by Harvard Medical School professor Walter Bradford Cannon.
Sweating:
The opposite to goose bumps, sweating keeps us cool. Although it often makes us feel hotter, it is essential, otherwise we would suffer heatstroke. According to the Journal of Applied Physiology, we have around two million sweat glands.
Snot:
Researchers at the University of Waikato in New Zealand revealed mucus is actually one of nature’s ingenious traps, evolved to prevent nasty germs making it through our noses and into our lungs
Sneezing:
While mucus provides a barrier against viruses entering our bodies through our airways, its side-kick sneezing is evolution’s solution to getting rid of the germs for good. The body developed it as a way of combating allergens.
Crying:
Along with moistening our eyeballs, tears also act as a signal to those closest to us. The theory is that, crying developed as discreet signal to convey that we were vulnerable, which predators could not pick up on. And we are the only animal on the planet which exhibits this particular behavior.
