Nature’s 8 bizarre bodyguards you didn’t know until now!

Must read

Most people don’t know that nature provides several bodyguards such as blushing and itching, and have no idea what are their individual functions.

Ever wondered why wrinkles over your fingertips when you soak them for a long time in water? Those are used to help grip the slippery surface better. This discovery was recently made by researchers at the Newcastle University and soon scientists from all over the world became curious about the other seemingly useless phenomenon occurring within our bodies. However, remember that we are the product of millions of years of evolution and almost every organ in our body works in the most optimized way possible.

Check below the other bodyguards present in our bodies.

1. Itching

Itching has puzzled scientists for several decades but there is still no definite answer behind its occurrence.Dr Zhou-Feng Chen from Washington University School of Medicine Pain Centre believes he has the solution. He thinks it is a form of perception. One can compare this to the whiskers present in a cat. The brain senses that something isn’t right in a particular part of the body from signals sent by the skin and it then sends a response for itching. This can temporarily solve the problem but if it an infection, then itching for a prolonged period of time can cause more damage too.

2. Goosebumps

Goosebumps are small pimples which appear when we feel cold. But what is the reason begins their appearance? Turns out they can actually keep away the cold; they provide a lot of heat within a short period of time. Muscles contract causing goose bumps, which prevent loss of heat.

3. Sweat

Almost everyone knows why we sweat; it helps in keeping our bodies cool during the summer. In fact, without sweating, people living in hotter countries could suffer heat strokes and even die during extremely hot days. The Journal of Applied Physiology reports that there are around 2 million sweat glands on out body.

4. Blushing

Blushing denotes that someone is embarrassed and it is best to leave that person alone for some time. Psychologists believe that it came into existence as a result of how human beings interact with each other.

5. Snot

Snot isn’t really preferred by any human beings, no doubt about that. But they actually play a vital function in our bodies. According to University of Waikato, this is crucial for trapping various germs that could have entered into our lungs through nostrils and cause a lot of damage.

6. Crying

Human beings are often ashamed of crying, but they actually help us in several ways.Other than keeping our eyes moist, they also send signals to people around us. Researchers believe that we developed crying so that we could signal other human beings without other creatures understanding that. We probably don’t need that anymore but for some reason we are still able to cry. What’s even stranger is that we are the only creatures on this planet who cry. So next time you feel like crying, don’t hold back.

7. Adrenaline rush

Adrenaline rush occurs whenever we feel we are in a threatened situation. This was particularly useful in the earlier days to escape from predators. This is also known as “flight or fight”. Nowadays, this can occur in various situations such as while giving an exam, or during an important interview. It provides with enough boost to go that extra mile.

8. Sneezing

Snot helps trap the germs but sneezing helps in removing these from the body. They are particularly useful to fight against allergens. An experiment conducted by the Discovery Channel showed its average speed to be around 40 mph.
