But FYI, there are scientific reasons behind these responses. These responses can be for the purpose of protection of organs or as a means to perform an activity better. These responses are involuntary most of the times and happen in just a jiffy, under special circumstances. Why does our skin prune when exposed to immense water, why do we blink when exposed to a strong source of light and why do we get goosebumps? The human body is a masterpiece in itself which is still a big mystery for the researchers, even in the 21st Century.But, these are everyday things which one must be aware of and the reasons behind them.

Why do we encounter goosebumps?

This is an involuntary and an evolutionary trait of the human body, wherein the hair straighten as a response to threatening situations or to provide warmth in unsavory cold weather conditions.

Why do we get butterflies in our stomach?

This is a fluttery feeling when on a first date or any such experiences. This is human body's fight or flight response in times of threat to survival. This is when one is freaking out that the adrenaline secretion makes the stomach extra-sensitive to cause the butterfly sensation.

Why do we yawn?

Most of the times it is due to lack of sleep, but it is also a way to lower the temperature of the brain. Well, did any of you know the second reason?

Why do we stretch after waking up?

Why do we get that sudden myoclonic jerk?

This is a sudden jolt that you get when you are about to drift into deep sleep. This depends on how tired you are. The human brain misinterprets the slower breathing and relaxed muscles as signs of death, so it jolts you up to keep you alive, instead of letting you sleep.

Why do we see those floaters in the distant sky?

This is because our eyes are made up of a jelly called vitreous fluid. This undergoes many changes with age. Tiny fibres of this unite together to form clumps which are large enough to be visible
