Anorexia nervosa is a serious mental health condition and a potentially life threatening eating disorder. However, with the right treatment, recovery is possible.

The exact cause of anorexia is not known, but research suggests that a combination of certain personality traits, emotions, and thinking patterns, as well as biological and environmental factors might be responsible.

People with anorexia often use food and eating as a way to gain a sense of control when other areas of their lives are very stressful or when they feel overwhelmed. Feelings of inadequacy, low self-esteem, anxiety, anger, or loneliness also might contribute to the development of the disorder. In addition, people with eating disorders might have troubled relationships, or have a history of being teased about their size or weight. Pressure from peers and a society that equates thinness and physical appearance with beauty also can have an impact on the development of anorexia.

Eating disorders also might have physical causes. Changes in hormones that control how the body and mind maintain mood, appetite, thinking, and memory might foster eating disorders. The fact that anorexia nervosa tends to run in families also suggests that a susceptibility to the disorder might partially be hereditary.

Deep sleep or slow wave sleep is the third stage of non-REM sleep. Although the body completes a few cycles throughout the night, the third stage occurs in longer periods during the first part of the night.

In the body, the heart rate and breathing rate are at their lowest during this part of the sleep cycle. The muscles and eyes are also very relaxed, and the brain waves become even slower.

It may be very difficult to wake someone from this stage of sleep, which is when sleep disorders, such as sleepwalking, occur.

This stage of sleep also helps the brain rest and recover from a day of thinking, allowing it to replenish energy in the form of glucose for the next day.

Deep sleep also plays a role in keeping the hormones balanced. The pituitary gland secretes human growth hormone during this stage, which helps tissues in the body grow and regenerate cells.

Importantly, a person has to get enough deep sleep for these functions to take place. The amount of deep sleep that a person has will relate to how much overall sleep they get. Sleeping 7 to 9 hours is the recommendation for most adults, which will usually give the body plenty of time in the deeper states of sleep.
