Exercise and addiction

“The brain releases dopamine, the “reward chemical” in response to any form of pleasure, be that exercise, sex, drugs, alcohol or food. Unfortunately, some people become addicted to dopamine and dependent on the substances that produce it, like drugs or alcohol (and more rarely, food and sex). On the bright side, exercise can help in addiction recovery. Short exercise sessions can also effectively distract drug oralcohol addicts, making them de-prioritize cravings (at least in the short term). Working out when on the wagon has other benefits, too. Alcohol abuse disrupts many body processes, including circadian rhythms. As a result, alcoholics find they can’t fall asleep (or stay asleep) without drinking. Exercise can help reboot the body clock, helping people hit the hay at the right time. ”  Sophia Breene,  Huffington post.
