Studies demonstrate that physical exercise during recovery helps your mind and body. Further research shows that exercise can improve your sense of well-being and increase the amount of new nerve connections in the brain, which help your brain heal from the harm that your drug of choice has caused.
As the body and mind continue to return to a more normal state, many people in recovery find that exercise also helps restore a normal sleep schedule. Improved long-term physical fitness helps with cardiovascular health and diabetes, lowers the risk of some types of cancers, and stimulates the immune system. It can even help alleviate depression symptoms.
