What Happens to Your Body During an Infrared Sauna Session
🔸 Core temperature rises: Infrared heat warms your body directly, gently elevating core temperature.
🔸 Heart rate elevates: Heat exposure raises heart rate in a way similar to light cardiovascular activity.
🔸 Circulation improves: Blood vessels dilate, increasing blood flow and nutrient delivery to tissues.
🔸 Deep sweating supports detox pathways: Sweat production increases, aiding the body’s natural elimination of waste.
🔸 Nervous system shifts toward relaxation: Heat promotes endorphin release and lowers stress responses for calm and clarity.
