Fresh pure air is essential to life and good health. We can live for weeks without food, days without water, but only minutes without air. Every cell in our bodies needs oxygen to function and if we breathe polluted air, we force our cells to function on a less than optimal level on less than pure air.
In order to have good health, we need good blood. Through the blood, waste is removed, repairs are made, and the body is nourished. When the blood is supplied with nutritious food and cleaned and vitalized by the breathing in of fresh clean air, it carries life and vigor to all parts of the body.
So in order to have good blood, we need to breathe well and we need to breathe fresh air. It's free and it alkalizes and electrifies the entire system. Full deep breaths of pure air-not polluted or smoke filled air- will fill the lungs with oxygen and purify the blood. Deep breaths sooth the nerves. The age old advice to take deep breaths when you're angry to calm yourself down is good advice. It works. Try deep breathing before bed and you might find it also helps you to sleep better.
The lungs need freedom. Restrictive clothing restricts the breathing as does poor posture. When your mother told you to sit up straight, she may not have known why that was a good idea, but she was onto something. Good posture whether standing or sitting helps to promote good breathing.
Superficial breathing has become a habit for most people and the lungs lose their power to expand. Thus an insufficient supply of oxygen is received. The waste which should be expelled when you exhale is retained and absorbed into the blood thus causing a host of problems.
If you work in a office with poor ventilation you know that there's a lot of sickness in those buildings. Not only are the people hunched over computers restricting their breathing, they are also breathing impure stale air. Close confinement indoors has and continues to make many people pale, feeble, and sickly. They keep breathing the same old recycled impure air with the impurities that they and others exhale. Those impurities are reabsorbed into the system, polluting the body. A lot of this could be avoided just by a supply of fresh air.
Something you should do daily in your home or office is open the windows to allow some fresh air in. Five to 10 minutes at a time twice a day would do wonders. It doesn't matter if it's cold out. Your heating bill may go up a little but you'll feel better and have better health as a result.
Exercise forces one to breathe deep. I like to exercise outdoors regardless of the weather. When I do, I breathe in fresh pure air that brings life and vitality to my entire body. Try it. You'll like it.
