June 23, 2006, Newsletter Issue #22: Breathing, Nutrition, and Brain Functions
Tip of the Week
Breathing can deeply affect many bodily functions. Deep breathing, for one thing, when added to diet and exercise, is able to enhance fat burning - a technique used in the popular 'Negative Calorie Diet' and the 'Oxycise' weight loss program. However, deep breathing is not free from negative effects, many of them aiming blood vessels including those in the brain. From this standpoint, deep breathing doesn't seem to be a feasible method to improve learning and memory.
On the other hand, shallow slow breathing can help opening the vessels thus improving the blood flow to the brain. It also calms the nervous system and can helps to concentrate. Shallow breathing leads to a healthy concentration of carbon dioxide in the blood (hypercapnia) resulting in the increased concentration of endorphins in blood. Endorphins are natural brain chemicals that are very versatile - their effects include stress protection, emotional balance, and memory improvement.
