Most active yoga practices will raise a sweat, though hot yoga guarantees it. Using infrared heating systems, forced air systems or space heaters, these classes can vary between 32-40C depending on the style – although commonly associated with Bikram, Power Vinyasa and Moksha also use heated rooms as part of their practice. Hot yoga raises your heart rate to increase your workout, encourages detoxification through sweat and helps to warm up your muscles quickly, making deeper stretches easier in a shorter period of time.
