There are many theories and studies that have proven the benefits of sleep on memory, neuroplasticity, biosynthesis of chemicals, helping to detoxify and excretion of waste products from the body, even prophylactic cellular maintenance. Moreover, there is a well-known importance of sleep in mood regulation and balancing energy requirements of our body.

Sleep also plays a vital role in metabolic activities of our body, any disturbance in sleep are having a direct effect on health from simple agitation to ischemic heart disease.

Sleep requirements are variable throughout the life cycle, as the national sleep foundation suggested, the minimum sleep requirement for young adults is 7-9 hours of good quality sleep. Both the quality and quantity of sleep are important. Sleep is divided into two major stages Rapid Eye movement (REM) and Non-Rapid eye movement (NREM).


Both these stages of sleep are playing vital functions in the sleep process. For example, NREM sleep serves as a restorative phase and satisfies metabolic needs, whereas REM sleep is when new information is processed and stored into our memory banks. Sleep process is controlled by two processes as a circadian process (daily) rhythm. This is controlled by a central “biological clock” (Suprachiasmatic nucleus – SCN) Several inputs also influence this clock, especially light and melatonin. Sleep is also a homeostatic process, the longer we are awake the more sleep debt we accumulate.

Being Psychiatrists, we are dealing with sleep problems for patients as we know prolonged sleep deprivation sometimes lead to ego disorganization, hallucinations and delusions. As well as this, REM-deprived patients may exhibit irritability and lethargy. What can be done to help to have a good quality of sleep? Studies have suggested NREM sleep is increased after exercise, so regular exercise can play an important role here. We also need to consider some relaxation tips to have a refreshing sleep.
