Depression is due to a physical change in the brain.  Certain areas of the brain shrink and stop functioning, which effects learning, attention, energy and motivation.  Some neuroscientists call this the Hibernation Effect. One of the significant studies to correlate the benefits of exercise and depression found that  for every 50 minutes of weekly exercise there is a 50% drop in the odds of being depressed.  Human beings are social animals, so to fight depression, it is best to choose and exercise with others to make connections.  Also being outside helps to further stimulate the senses.

According to the World Health Organization (W.H.O.), depression is the leading cause of disability in the United States and Canada.  About 17% of American adults experience depression costing over 26 BILLION dollars each year.  Every 17 minutes in the Unites States someone commits suicide.  There are different kinds of depression and the full range of emotional reactions that can manifest.  There is no blood test for depression nor is there a fail proof psychological test.  Of course, hormonal imbalances can be detected in some people, but not the majority of those with depression.  Many studies, around the world, have looked at the correlation of exercise and depression, and all of them came to the same conclusion: Those who exercise, 2-3 times per week, experience significantly less depression.

Hippocrates, the father of medicine, and whom the Hippocratic Oath was named and recited by all medical doctors, had a simple health theory.  That health and emotions came from the heart, and that is where treatment should start for maladies of mood.  Of course, Hippocrates lived 2400 years ago and could not have known that a naturally occurring hormone is produced in the heart.  During exercise, increased heart rate releases this hormone, called Atrial Natriuretic Peptide (ANP), into the blood stream.  Once in the brain it blunts stress and anxiety and helps to regulate mood.

Studies have shown, both stress and inactivity play big roles in the development of many autoimmune diseases and conditions such as Chronic Fatigue Syndrome and Fibromyalgia.  The more stress you have the more your body needs you to move to keep your brain happy!  The office or work place, is often the primary source of stress for a lot of people, and a good place to look for the benefits of exercise.  Employees who regularly exercise are shown to be more productive and have less absenteeism.

Studies have shown that people with Parkinson's Disease that are encouraged to exercise, on a stationary bike, can reduce the effect of the disease. In the brain, the mild stress of exercise fortifies the infrastructure of our nerve cells by activating genes to produce certain proteins that protect the cells against damage and disease, such as Alzheimer's, Parkinson's and Dementia.

The mind is so powerful that we can set off the "stress" response just by imagining ourselves in a threatening situation.  Thus, activating our "Flight or Fight" response.  This prepares our body for movement.  Physical activity is the natural way to prevent the negative consequences of stress.  The body's response to chronic stress causes an increase in the release of the hormone "Cortisol." This hormone directs the body to create and store fat reserves, especially around the abdomen.  We need to move in order to prevent that storage from happening.
