As the Bhastrika pranayama gets longer, the body will start to generate higher levels of heat and the metabolism will run faster. It is similar to the physical foundations of Tummo yoga where the student heats up the body with forceful exhalation breath, but in Tummo yoga, much more visualization on energy centers and psychic heat is usually practiced. Since Bhastrika pranayama creates heat in the body, it is better practiced in cooler times such as wintertime or in the mornings when the temperature is low. Like all pranayama, it is better to be practiced after yoga asanas.
