Pranayama (Breath Work)

A 2017 study in the *Journal of Alternative and Complementary Medicine* found that 20 minutes of Nadi Shodhana (alternate nostril breathing) reduces heart rate by an average of 15 beats per minute. This technique, alongside Ujjayi breath, improves lung capacity by up to 20% after just two weeks of daily practice, according to data from the International Journal of Yoga. It is the easiest yoga practice to start at home without any equipment, making it 30% more accessible than typical physical asana routines. Evidence also shows that consistent pranayama lowers cortisol levels by 14%, offering a measurable edge over simple relaxation exercises.
