An exercise session can redirect your focus to controlling the movements of your body, or, in the case of a competitive sport like tennis, to winning the game. The brain cells have an opportunity to be rested and restored during exercise.
Exercise can also raise your confidence in your abilities.
Exercise gives the thyroxine and adrenaline produced by your body a mechanism by which to expend themselves. Rather than unleashing the negative emotions of anger, frustration and irritability, the stress hormones deplete themselves and are replaced with increasing levels of the exercise chemicals serotonin and endorphins.
How Does Serotonin Reduce Stress?This important neurotransmitter aids in the transference of signals from one neuron to another. Studies have found that people who suffer from depression have low levels of serotonin.
