Bikram yoga aims toward general wellness and claims the heated studio facilitates deeper stretching, injury prevention, and stress and tension relief. Bikram yoga is claimed to systematically stimulate and restore health to every muscle, joint, and organ of the body. There are two complementary aspects of the 26 exercises, asanas (postures) and pranayama (breathing exercises), though many other branches of yoga also use these methods. According to Choudhury, many people only use up to 50 percent of their lung capacity; the lungs must be stretched in order to (through practice) withstand holding more oxygen. When one is practicing pranayama s/he will eventually be able to enhance oxygen conversion and absorption, as well as improve blood circulation. (Choudhury, 2007) This is true of any cardiovascular activity.

It is common for beginners to experience dizziness and nausea. Like many forms of yoga, immense amounts of focus and discipline are required to complete a session.  There is much controversy as to whether or not performing strenuous exercise in a room over 100 degrees is safe.

Choudhury claims that blood circulation is affected immensely during Bikram Yoga because of two processes called extension and compression. These two dynamics are said to work together to deliver fresh oxygen to every joint, muscle, and organ within the human body. While performing a specific asana (pose), the body is stretching or compressing a certain part of the body, thus cutting off circulation temporarily. This restriction of circulation causes the heart to pump more blood in reaction to the shortage. The pumping of excess, fresh blood is called extension. Once the asana is complete and the individual comes out of the posture, the new oxygenated blood is able to rejuvenate the arteries that were being compressed. Because of the volume change and influx of fresh blood, it is said that infection, bacteria, and toxins can be released through this process. (2007)
