If you have noticed that you are on edge, tense or excessively nervous, the problem may be associated with increased levels of stress. This produces higher levels of toxic hormones in your body that can lead to a variety of health complications such as weight gain, chronic fatigue and chronic migraines or headaches. Exercise isn't just essential for physical health but is also necessary for emotional and mental well being. Daily exercise is one of the most effective natural remedies for stress.
