What sleep deprivation does to you.

We have to get enough sleep if we want our bodies to function properly. Sleep has a positive influence on how our nervous system functions. People who are sleep deprived and drowsy struggle to concentrate. They end up having memory lapses, decreased physical performance and some may not be able to carry out calculations accurately. In extreme cases one may start hallucinating or experiencing mood swings.

MENTAL ISSUES - Memory lapses, Unable to concentrate, Mood swings, Irritability, Drowsiness, Neurons begin to malfunction, Neural connections begin to deteriorate, Calculation impairment

PHYSIOLOGICAL ISSUES - Heart rate fluctuations, Constant yawning, Impaired immune system, Reduced cell growth, reduced cell repair, reduction in physical performance

ADVANTAGES OF SLEEP - When we sleep, the neurons get a chance to shut down and carry out some self-repairs. Without sleep, the neurons end up getting polluted and depleted. As we sleep, the brain gets a chance to make neural connections which may otherwise degenerate as a result of the lack of activity. When we are in deep sleep, there is an heightened production of growth hormones and cell production. There is also reduced protein breakdown. Proteins are responsible for the repair of cells damaged by ultraviolet rays or even stress and this is why deep sleep can also be referred to as beauty sleep. During deep sleep, the part of the brain that deals with social interactions, decision making and emotional experiences reduces activity and this helps in optimizing emotions when we are awake.
