Most patients should avoid saunas, steam rooms, hot tubs, and infrared sauna until incisions are fully sealed and the surgeon has cleared them, often at least 4 to 6 weeks after an uncomplicated breast augmentation. Heat can increase swelling, throbbing, dehydration, bruising, and inflammation, and sweating around healing incisions may irritate the skin or increase infection risk. Infrared sauna still heats the body, so the same basic precautions apply. Ask your own surgeon because implant pocket, incision location, dressings, drains, and healing progress all matter. When you restart, keep the first sessions short, stay well hydrated, avoid very high heat, and stop if you notice breast tightness, increased swelling, redness, drainage, fever, or worsening pain. Those symptoms should be checked by your surgical team before continuing sauna use.
