Alcohol might seem like a good way to wind down at the end of the day, but it might also contribute to feelings of depression and anxiety in many individuals. Alcohol is a depressant, which means it reduces serotonin, a neurotransmitter responsible for stabilizing the mood. Even a little bit of alcohol can affect an individual's sleep, and not enough rest increases their chances of experiencing depression and anxiety. Alcohol also stimulates the brain to increase feelings of stress and anxiety. In place of beer or other glutinous alcoholic drinks, opt for a glass of red wine (if necessary) followed by a glass of mineral water.
