Mouth Breathing During Exercise May Increase Your Risk for Asthma and Cardiac Problems (By Dr. Mercola)
One of the most basic requirements for an effective exercise session is good oxygenation of your muscles and organs. You can actually control how well your tissues are being oxygenated by how you breathe.
But if you’re like most people, you take your breathing for granted. After all, it’s so automatic! You may not realize that there is an optimal way to breathe to increase body oxygenation and improve your health. There is a chance you may be doing it the wrong way without even realizing it.
