Many people are curious about things they observed to happen but never knew why it happens so.In this short post I will explain about 10 of the things why our body do so before we sleep.

First-The twitch before we sleep.

This is due to the brain misinterprete the action of sleeping as falling down.When we engage in sleeping,the brain misinterprete the action of sleeping as though we are falling down,so our muscles twitch as a response to protect ourselves from the misleading fall.Some people also suggest that it is because the brain sends signal to the muscles to twitch to signify that the body is really going into a state of sleeping,not of other pathological or neurological disorder.Also,it might be the brain's action of sending signals to ensure that the muscles are working fine before sleeping,as the action of sleeping confuses the brain for a various things as the muscles will not be able to move under conscious state for a period of time.

Second-Do not sleep if you can't

Since the early times there had been a rumour stating that if you can't get to sleep,counting sheep helps.Well the action of counting sheep does not make you sleepy neither does it helps you to sleep.The action of counting sheep(it can be anything for instance) stimulates your brain into passive calculation.Your brain does not get relax in the process of coutning sheep.Also,if one tends to do most non-sleeping activities in the bedroom,you can subconsciously be 'trained' or be resistant to fall asleep in the bedroom.It is because that your brain interprete that you rbedroom is a place whereby you carry out most activities,such that it does not recognize your bedroom as a place to relax,therefore you can develop resistancy to fall asleep in your bedroom as days go by.

Third-Yawn,yawn,yawn~

Right now there is no definite explaination in which why humans yawn.However,one closest theory that is taught to all medical students is that the action of yawning yields a higher exchange of more oxygen-carbon dioxide flow in order to allow more oxygen-carbon dioxide exchange in which may stimulates or awoken the brain further.

Fourth-Circling before the sleeping

Most pet rearers may notice this traits of their pets that they tend to move around in circles before they sleep.It could be explained that this trait is carried over for a long time from the ancestors of the animals that the action of circling before sleep if to make the spot where they are going to sleep more comfortable.

Fifth-Eating before sleeping

Eating right before sleeping may affect individuals differently.But the most common effect of eating right before sleeping is that the affected individuals tend to have more difficulty sleeping due to the actions of digestion in the stomach of the food received right before sleeping.This is turns stimulates the brain resulting difficulty in entering sleeping.However some people may still have the habit to sleep better by eating right before they sleep,so it affects different people.However sleeping itself does requires energy.If one enters to sleep with an empty stomach the body will not be able to enter a total deep sleep whereby the body fully rested.This is due to the insufficient energy used to burn for the deep sleep.So having a light snack before sleep is generally a good idea if one has difficulty sleeping.

Sixth-I dreamt of falling in my sleep!

Scientists has came up with a theory that is may be possible that during our dreaming of falling down in our sleep,our body is shifting our balance over another place,perhaps due to the action of turning around.The brain interprete the message of falling down as our sense of balance is shifted to another spot.During the dreaming of falling down,it is the action of our sense of balance trying to adapt to another balancing spot to neutralise the sudden movement in our sense of balance.

Seventh-Seeing in dreams,possible when one is blind?

Generally if one is bornt blind,there will not be any perceptual images 'saved' in the brain to load the data during the concurrent of dreams.However the dreams are possible to compose of other senses stimulation such as sounds and smell.Whereas if one is legally blind,then the images will be perceptual during the time before the person is blind.

Eighth-What about hearing when one is deaf?

Most probably,yes.Even if the person is born deaf,it is still possible for one to distinguish the inner voice and the outside voice,as though he or she is not deaf.Every person has a inner voice,provided he or she knows the pronounciation inside their mind,so it is generally possible to be hearing things in the dreams even when one is born deaf,where no sound is received for the entire of his or her life.

Ninth-Is it healthy for kids to wet their bed?

There is two reasons for this observation.One is that the children's bladder is too small to hold the excess urine secreted during the course of sleeping.Two is that most children are heavy sleepers,so they might not know that they have a need to empty their bladder on their course of sleeping.
