Successful stress management is simply a process where one either eliminates or reduces destructive stress, or changes it into constructive stress.
Exercise is an effective solution. It's a proven 'stress-buster' and has been shown to be beneficial in treating mild-to-moderate depression. Being fit and healthy helps one deal with the stresses of everyday life. Conversely, being in poor physical condition reduces the ability to handle stress, and increases the risk of developing stress-related illness.
Muscular relaxation techniques and exercise forms such as Tai Chi and Qigong (Chi Kung) can relax both body and mind. Neuro-linguistic programming (NLP) is a powerful tool to help deal with the perception and handling of stressful situations.
These techniques can all contribute to improving psychological health, being part of the holistic approach to health and fitness.
