I have never heard of a saying that there is a disease called "depression" and a medicine called "fitness"

Fitness is one of the most effective ways to relieve bad emotions.

Fitness can help the body secrete happy dopamine.

Light fitness exercise is like a protective agent for bad mood. It can promote the replacement rate of chemicals in the brain, reduce stress and anxiety, and make you feel happier and more relaxed. Studies have shown that the more depressed you are, the more benefits physical exercise can bring to your body. Exercise and fitness can be compared to natural sleeping pills. In a recent study, the National Sleep Foundation found that as many as 67% people who exercise regularly have high-quality sleep at night. Whether you choose to exercise in the morning, during the day or at night, your sleep quality will benefit a lot.
