It contains many toxic metals such as lead, cadmium, nickel, antimony, radioactive pol-210, arsenic and so on. These are contained in many pesticides (surge report).
Breathing is a natural thing: breathing, exhale. Ok, there is actually a wrong way to get oxygen into your system through your lungs. Below is a hint on how to make the best use of the lung by Mark Lawn, a pulmonary help line respiratory therapist from the American Lung Association. Human is "abdominal ventilator", just above your stomach is the main muscle in the process of breathing - the diaphragm. Appropriate respiration begins from the nose, when the diaphragm contracts, the abdomen expands, the lungs fill the air and move to the stomach. "This is the most effective way to breathe, as it pulls the lungs and causes negative pressure in the chest to let air flow into the lungs."
Place one hand on your chest and the other on your stomach. Inflate your stomach while breathing in through your nose. This means that you are using a diaphragm to breathe so that air enters the lungs directly. Move the upper body as small as possible, keeping the movement gentle. Spit out slowly and evenly from the nose. Please repeat the rhythm repeatedly. Your goal is to breathe 8 to 12 times per minute - breathing and respiration once again as breathing. Please practice until it becomes a habit, and then go to regular breathing if you feel uneasy next time. You can truly learn how to relax and reduce unnecessary physical burden when needed. Leisure guide is below.
Why is this? Understand, take a deep breath, pay close attention to that feeling. Please take a deep breath now. Several have disappeared. When breathing through your nose, you should feel energy flowing in your heart and through your consciousness. This feeling is blocked when you breathe through your mouth. I just feel that the air enters the lungs. Breathing supplies more oxygen to the brain than mouth breathing. It also allows you to filter and purify the air you breathe before reaching the lungs.
