Sleep is a naturally recurring state of mind and body characterized by altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary activities. Sleep is very important in calming down the body, bringing cortisol levels back to normal and hence in controlling stress.

A good night sleep is not a luxury. Don’t cut down your sleeping time for the sake of work, it may look as if it helps one to achieve more, but eventually doing that habitually may reduce one’s lifespan and thereby achieving less. If you want to avoid stress disease, then you need to believe that you need adequate sleep and ensure that you get it.

Too much sleep is hardly ever a problem for healthy people. Your body would naturally wake up when you have had enough sleep.

Sleep needs vary among individuals and at different ages but the variation is not much. An adult needs seven to nine hours of sleep uninterrupted in the night. Those who sleep for few hours, but believe that they don’t need more and seem to be coping, are already adapted to their high adrenaline level.

The sleep you get is like a bank account with a minimum balance penalty. When you get up to 8 or 9 hours, you have extra deposit and if occasionally you don’t get up to that, you are not too much over drawn.

Withdrawing without replacing habitually will make the account collapse some day and that’s what happens to the body, if you don’t get enough sleep. It can reduce one’s quality of life and shorten one’s lifespan. You could improve your physical and emotional health if you just sleep more.
