Want to learn more about exercise and depression? Many studies indicate that people who exercise regularly benefit with a positive boost in mood and lower rates of depression.

What are the psychological benefits of exercise with depression?

Improved self-esteem is a key psychological benefit of regular physical activity. When you exercise, your body releases chemicals called endorphins. These endorphins interact with the receptors in your brain that reduce your perception of pain.

Endorphins also trigger a positive feeling in the body, similar to that of morphine. For example, the feeling that follows a run or workout is often described as "euphoric." That feeling, known as a "runner's high," can be accompanied by a positive and energizing outlook on life.

Endorphins act as analgesics, which means they diminish the perception of pain. They also act as sedatives. They are manufactured in your brain, spinal cord, and many other parts of your body and are released in response to brain chemicals called neurotransmitters. The neuron receptors endorphins bind to are the same ones that bind some pain medicines. However, unlike with morphine, the activation of these receptors by the body's endorphins does not lead to addiction or dependence.

Regular exercise has been proven to help:

Reduce stress
Ward off anxiety and feelings of depression
Boost self-esteem
Improve sleep

Exercise also has these added health benefits:

It strengthens your heart.
It increases energy levels.
It lowers blood pressure.
It improves muscle tone and strength.
It strengthens and builds bones.
It helps reduce body fat.
It makes you look fit and healthy.

Is exercise a treatment for clinical depression?

Research has shown that exercise is an effective but often underused treatment for mild to moderate depression.

Do particular types of exercise help depression?

It appears that any form of exercise can help depression. Some examples of moderate exercise include:

Biking
Dancing
Gardening
Golf (walking instead of using the cart)
Housework, especially sweeping, mopping, or vacuuming
Jogging at a moderate pace
Low-impact aerobics
Playing tennis
Swimming
Walking
Yard work, especially mowing or raking
Yoga

Because strong social support is important for those with depression, joining a group exercise class may be beneficial. Or you can exercise with a close friend or your partner. In doing so, you will benefit from the physical activity and emotional comfort, knowing that others are supportive of you.

Do I need to check with my doctor before starting an exercise program?

For most people, it is OK to start an exercise program without checking with a health care provider. However, if you have not exercised in a while, are over age 50, or have a medical condition such as diabetes or heart disease, contact your health care provider before starting an exercise program.
