Very few of us know that yawning is more than just an sign of doziness? Yawning is supposedly intended to allow the brain to cool down after an overpowering amount of work that may have caused it to overload.

Whether we recognize it or not, stretching is natural, as it prepares the body for expected physical work which we suppose them to take during the day. At the same time, stretching works the muscles, restores blood flow, and improves our mood



Hiccups are actually associated to the body’s stomach and diaphragm .When we eat very rapidly, ingest large pieces of food, or simply overeat, our pneumogastric nerve can become aggravated. This is closely connected to our stomach and diaphragm. The result is a bout of hiccups.

Myoclonic jerks


This refers to that weird sensation when you lie down to go to sleep, and as you begin to drift off your body is jolted for a second by what seems like an electric shock. In this instant, all of your muscles shudder so powerfully that you almost fall out of bed, and you wake up straightaway.

This incident is the result of the fact that when you begin to fall asleep, the rate of your breathing quickly falls, whilst your pulse slows down only very a little and your muscles are calm. Remarkably, your brain interprets these developments as heralding death. So it tries to save you by giving you a jolt.

The wrinkles that appear on the skin of your hands have a significant function. When our body realizes that the amount of moisture around us increases, it adapts through the wrinkling of the skin. The wrinkling is a normal bodily reaction that makes the grip on smooth and slippery surfaces easier.

Loss of memory

Loss of memory often happens after the incidence of the most disagreeable experiences. Our brains literally erase the most dreadful moments from our memories.



Goosebumps are another way for the body to adapt. It normally occurs in cold climates wherein the amount of heat our body loses is reduced. Which makes it easier to warm ourselves in inhospitable climatic conditions?



This may seem obvious, but tears are the body’s tools meant for emotional defense. According to scientists, the body finds a way to ease or distract the person from pain through a different yet strong source of irritation.
