Through millions of years, movement was part of our biological necessity.. Movement was necessary to hunt, to escape predators, to explore and to find a mate. Organisms developed a brain (nervous system) to coordinate movement as eloquently explain by neuroscientist Daniel Wolpert in his 2011 TED talk, The Real Reasons for Brains.
It is only recently that we limit movement by sitting, driving, taking the escalator, or controlling equipment that performs the actual physical labor. We interfere with our evolutionary developed physiology when we reduce or even eliminate movement for the sake of efficiency. Lack of movement, “sitting disease”, is a significant contributor and causal factor in illness. It also increases the stress response, negative mood and depression and reduces cognitive activity. Take charge and reduce illness when you integrate purposeful exercise (walking, running, dancing, etc.) into your life style.
Exercise is the most effective behavioral technique for self-regulation of mood in healthy people as summarized in the superb article, The Effects of Acute Exercise on Mood, Cognition, Neurophysiology, and Neurochemical Pathways: A Review, Dr. Julia C. Basso and Wendy A. Suzuki of the Center for Neural Science, New York University, New York, NY, USA. The robust research findings show that acute exercise improves mood, significantly reduces depression, tension, anger, fatigue, and confusion. In addition, acute exercise improves symptoms associated with psychological disorders such as depression, anxiety, schizophrenia, and post-traumatic stress disorder. Exercise decreases the risk of type 2 diabetes, coronary heart disease and stress-related blood pressure response by inhibiting the sympathetic nervous system response to stress. For a detailed summary, see the blogs, What is the best single thing we can do for our health and Healthy movement is the new aging.
Finally, the authors also review the relevant neurophysiological, and neurochemical processes that are affected by exercise. What is most interesting are the findings that “acute exercise primarily enhances executive functions dependent on the prefrontal cortex including attention, working memory, problem solving, cognitive flexibility, verbal fluency, decision making, and inhibitory control. These positive changes have been demonstrated to occur with very low to very high exercise intensities, with effects lasting for up to two hours after the end of the exercise bout.”
As the authors state, “We show that the three most consistent cognitive/behavioral effects of a single bout of exercise in humans are improved executive functions, enhanced mood states, and decreased stress levels.”
Even though the findings are clear that movement/exercise is a powerful “drug” to improve our health, most health professionals focus on sitting treatment and prescribing pharmaceutical agents. Possibly, a treatment session should start with fun physical exercise and followed by therapy. Remember, if you feel blah, have lower energy, feel frustrated or irritated, get up and move. Movement and exercise will change your mood. You will experience what Peper and Lin (2012), have shown that less than minute of skipping in place will significantly improve your subjective energy level and mood. Get up and skip in place, then observe how much better you feel. Then sit again read the article by Dr. Julia C. Basso and Wendy A.

A major factor that contributes to illness and health is how we cope with stress. Learning stress management techniques and integrating them into our daily life can significantly reduce illness and discomfort. Patients report significant improvement in numerous disorders such as hypertension, headaches, cancer, pain, or arthritis.
A great health resource are the short YouTube videos by Dr. Mike Evans who is founder of the Health Design Lab at the Li Ka Shing Knowledge Institute, an Associate Professor of Family Medicine and Public Health at the University of Toronto, and a staff physician at St. Michael’s Hospital. His informative short video clips cover a range of medical conditions from concussions to stopping smoking (see his website: http://www.myfavouritemedicine.com).
