Infrared Sauna in Boston
Cardiovascular conditioning, faster recovery, and cleaner skin — from 30 minutes of deep infrared heat.
Medically directed and founded by Olivia Kelly, NP, NP, RN — Licensed since 2003.
Infrared saunas heat your body directly with light rather than warming the air around you — meaning deeper penetration, longer tolerable sessions, and a more intense sweat at lower ambient temperatures. Growing research links regular infrared use to cardiovascular conditioning, reduced inflammation, improved sleep, and clearer skin. At IV League we offer infrared alongside cold plunge for our signature Fire & Ice recovery protocol.
Benefits
Why patients choose Infrared sauna
Cardiovascular conditioning
Infrared sessions produce a passive-cardio effect similar to moderate exercise — elevated heart rate, improved circulation, and blood pressure benefits with regular use.
Faster training recovery
Deep heat helps flush metabolic waste from muscles and reduces soreness. A go-to protocol for our athlete clients between hard sessions.
Skin clarity and detoxification
Deep sweating supports the skin's largest detox pathway and boosts circulation to the dermis. Regular users often notice clearer, brighter skin.
Sleep and stress
Post-sauna cooling triggers a parasympathetic (rest) response — many clients use evening sessions to wind down for deeper sleep.
