Sleep has multiple benefits right from good physical health to better mood, alertness to repair and rejuvenation of the body.

A good amount of research has been carried out to link insufficient sleep with mental illness. Sleep is important for cognitive function and memory.

Relationship between sleep and mental health

Brain activity fluctuates during sleep, either increasing or decreasing during different sleep stages that make up the sleep cycle.

Brain activity during sleep has profound implications on emotional and mental health.

During sleep, the brain tries to evaluate and remember thoughts and memories and lack of sleep prevents consolidation of positive emotional memories.

Research have shown that – 

1. People with insomnia have 10-17 times more likely to get depression & anxiety issues as compared with people without insomnia. Many people with depression also suffer from excessive daytime sleepiness.
2. Poor sleep has also been associated with post traumatic stress, eating disorders, delusions and hallucinations.
3. Specific sleep disorders like sleep apnoea, circadian rhythm disruption, sleep walking, nightmares, restless leg syndrome are all prevalent in those experiencing mental illness
4. Anxiety disorders have a strong association with sleep disorders. Worry and fear contribute to the state of hyperarousal in which the mind is racing leading to sleeplessness.
5. Insufficient sleep creates drowsiness during day time, this can lead to accidents during driving and at the office.
