Yoga is an ancient system of relaxation, exercise and healing that has origins in Indian philosophy. As a system of healing, it takes a primary approach of prevention, or keeping oneself well by the daily practice.
Yoga has undergone much scientific study, with various psychological and physical theories suggested. In human research, yoga has been shown to reduce heart rate and blood pressure, increase breath holding time and lung capacity, improve muscle relaxation and body composition, cause weight loss and increase overall physical endurance.
The recent study reviewed data from ten other studies that examined the effect of yoga on lung function. Researchers analyzed data on lung strength and how much air could be expelled in one breath.
Researchers found that lung function improved after ten weeks of yoga practice. Participants who were less fit before the study and participants who practiced more breathing exercises showed the greatest improvement.
