Insomnia

Abstract

Insomnia is a common sleep disorder, categorised as difficulty in falling sleep, difficulty staying asleep, early wakening or feeling unsatisfied by sleep, despite adequate time and opportunity to sleep.

Adequate sleep is essential for good health and overall quality of life. It is an essential function that allows the body and mind to recharge, critical for the ability to think clearly, be vigilant and alert, and sustain attention. In fact, sleep has been proven to improve memory recall, regulate metabolism, and reduce mental fatigue.

In general, adults require between seven and nine hours of sleep every night. Studies have shown that a lack of or a disruption of sleep may affect immunity and increase the risk for disease. Modern lifestyles, such as busy work schedules, day-to-day stressors or a disruptive bedroom environment, can reduce the amount and the quality of sleep.
