Exercise; Savior from depression

"Numerous studies have reported that physical activity is the best remedy for people suffering with depression."   

"However, it is important to note that increased physical activity is beneficial for people with other medical conditions too such as obesity, diabetes and cardiovascular disease and, of course, these conditions can affect people with depression."

This may be due to hormone changes and immune system imbalances that come with depression.

Spending time outdoors and exercising for at least 150 minutes weekly have shown to improve mood and depressive symptoms.

Some people with depression also have substance abuse problems. Alcohol or other drugs can interfere with sleep patterns, decrease motivation, and alter a person's mood.

Sleep may also play a role in depression. The body's natural sleep cycle creates mood-altering chemicals to match the time of day. Altering this natural cycle may affect how well the body can use these chemicals.

Most adults respond well when they get 7 to 8 hours of sleep, though the number varies from person to person.
