Toxins are the leading causes of human ailments.

Toxins are the leading causes of both physical and psychological ailments. When you have diseases like blood pressure, blood sugar, heart ailments, kidney failure, liver dysfunction, and any other primary internal problems, they are a sign that your blood cells have less oxygen and more toxic. There is a direct link between blood pressure and blood sugar and lack of oxygen level in the blood cell.

Excess toxin deposits causes a problem

Toxin comes to the body with your intake of kind of food, water, and air. Alcohol, Tobacco, and other chemical substances add to the deposit. Processed foods are also a source of the chemical that you accumulate in the body.  Usually, our internal system detoxifies it. But when it fails to do so, the toxin deposits causes a problem.

Pranayama detoxifies your internal system and refills with oxygen in the blood cells.

Here comes the usefulness of pranayama. Pranayama does two things simultaneously; it detoxifies your internal system and refills with oxygen in the blood cells. It rejuvenates the entire internal system. Eventually, all your ailments disappeared.

Your ailments disappeared as the oxygen level in your blood cells increased. 

Pranayama might not do much benefits if you do it in a air polluted environment i.e. polluted city because you would take toxins into your system along with the oxygen. So it is advisable to do pranayama in a natural and greenery environment.
