Symptoms of Sleep Disorders and Causes of Sleep Deprivation

Sleep and Health

Sleep is considered a complex and important process in the restoration and regeneration of the body, and it is also necessary for some physiological processes, such as organizing and creating experiences and combining memories.

Sleeping is one of the most important parts of the daily routine in a person’s life, as it constitutes nearly a third of the regular day, and sleep is no less important than other essentials such as water and food.

 People usually need eight hours of sleep a day, with individual differences. Sleep greatly affects many functions of the body's organs: the brain, nerves, heart, and lungs, as well as metabolism, mood, body immunity, and disease resistance.

The importance of sleep is demonstrated by the negative effects that patients suffer from, such as physical and psychological problems resulting from a disruption in the sleep process.  
In fact, sleep is affected by the body's daily changes, such as the body's physical and mental changes that take place within 24 hours. These changes are regulated by the nerves that respond to light, hormones, and heat. 
These elements are also components of the biological clock, which would naturally regulate the stages of sleep and waking.
