The Science Behind Hot Yoga: Wellness, Strength, and Detox in Every Session

Hot yoga refers to any style of yoga practiced in a heated room, typically between 90°F to 105°F (32°C to 40°C). The heat intensifies the physical challenge and promotes deeper stretching, increased circulation, and profuse sweating — which may aid detoxification.

According to a 2025 systematic review published in Sports Medicine – Open, hot yoga leads to:

• Improved flexibility and joint mobility due to warmed muscles and connective tissues.

• Enhanced cardiovascular fitness: The heat increases heart rate, mimicking aerobic exercise.

• Better glucose regulation: Studies show reduced blood sugar levels after consistent practice.

• Stress reduction and mental clarity: The combination of heat, breathwork, and movement supports parasympathetic nervous system activation.

• Skin health: Sweating may help clear pores and improve circulation to the skin.
