Stress and Exercise
Exercise helps relieve stress. That’s a fairly common sense belief these days, but it is also one backed up by a lot of careful scientific research.
Exercise causes the brain to produce a cocktail of helpful biochemicals that help reduce stress. Runners, for example, are familiar with that ‘endorphin high’ that comes from marathon workouts. That’s the result of the brain releasing an opiate-like substance that the body produces naturally to reduce pain. In extreme cases it leads to a sense of euphoria.
Along with endorphins there are other neuro-transmitters produced - serotonin, dopamine and norepinephrine - that also have beneficial effects as mood elevators. The effects of those is shown most clearly when they exist at too low levels - depression, anxiety and sometimes increased aggression.
