The primary function of serotonin is regulation of our emotions and it has been suggested that low levels may cause large mood swings and more impulsive behaviour. Noradrenalin on the other hand helps us interpret and act on emotions and combined with other regions of the brain, controls physical desires such as sleep, appetite and reaction to stress. According to the American Medical Association, heavy exercise may increase serotonin levels and these levels may last up to one hour after the workout.

It has also been suggested that prolonged exercise increases brain serotonergic activity. With respect to noradrenalin, it is a fact that this chemical is released with exercise, and data exists suggesting that both acute and chronic exercise bouts may play a role in the regulation of the deficient chemicals.

While there is a clear possibility that a link exists between serotonin, noradrenalin, depression and exercise, further research is needed.

Can exercise increase mood and help with those mildly depressed? The answer to this is clearly yes.

Whether you follow an exercise program or simply take part in some form of random activity, exercise without a doubt, increases your energy levels and improves your attitude and your ability to focus. Exercise may promote social behaviour, acceptance and fight boredom, and of course helps regulate weight and body image—improving appearance, self confidence and creating an overall feeling of well-being.
