Serotonin is a neurotransmitter that helps communicate messages between areas in the brain. Most brain cells are influenced by serotonin. Besides the brain, serotonin also affects the heart and muscles. When serotonin levels become unbalanced, a person may experience depression. People who suffer from depression usually have low levels of serotonin in their blood. Some people take supplements like St. John's Wart or tryptophan to help elevate serotonin levels; however, these supplements may not be effective. Antidepressant medications are usually successful in helping people boost serotonin levels, but there are also other ways to replenish serotonin.

Sit out in the sun for 20 to 30 minutes every day without wearing glasses to help replenish serotonin 1. Keep your eyes closed and relax while your body absorbs nutrients from the sun. Take walks outside. Try to spend as much time as possible outside in nature.
