Be it from a word-of-mouth, or a newspaper article, unreliable and mis-interpreted facts always keep us in the dark. To shed some light, we've brought for you, a simple yet comprehensive list of facts and myths about the human body. Read on to find out more.
Myth#1: Your hair grows back thicker and longer after a shave
AdvertisementPopular among women who dread shaving, this one is a total myth. What actually happens is that uncut hair is tapered off at the edges, which makes it appear thinner. Also, it is exposed to the sunlight, which makes it appear light, thus giving hair that comes up after shaving a bad reputation.
Myth#2: We use only 10% of our brains
This one is another falsity. We do use the entire brain, but not in one single go. This myth was debunked all thanks to recent brain damage studies.
Myth#3: Don't wake a sleepwalker
Contrary to the popular belief, waking up a sleepwalker is highly recommended. True, the sleepwalker may seem disoriented and dazed at first, but that's much better than tripping over something or getting hurt in some situation, which obviously he/she won't be aware of.
Myth#4: Different areas of our tongue can taste different things
The idea that different regions of the tongue correspond to different taste receptors has been making rounds since ages, and is totally a myth. Every area of the tongue can taste every taste.
Myth#5: Cracking your knuckles can cause arthritis.
If this was true, probably a large number of people today would be suffering from arthritis. Various researches performed to evaluate the association between osteoarthritis and cracking-knuckles have confirmed this. Habitual knuckling may not cause arthritis.
However beware, your hand grip is compromised. Studies suggest that habitual knuckle crackers are more likely to develop hand swelling and lower grip strength.
Myth#6: Fingernails and hair continue to grow even after death
Yet another result of a mis-interpretation, it does appear that the fingernails and hair have turned long after a person's death, but actually, it is merely the shrinking of the cuticle which makes it appear so.
Myth#7: You should drink 8 glasses of water a day
This one is probably one of the most popular myths making rounds. It's true that a good amount of water intake helps flush out toxins and keep away many diseases, mostly infections, but this very number was actually nothing but a result of a mis-interpretation of the word 'fluid' for eight.
