Do Infrared Sauna Blankets Really Work?

You Should Know: The benefits of traditional saunas are fairly well established. Frequent use is linked to reduced risk of heart disease, high blood pressure, and dementia. But installing one at home is a luxury many of us don’t have, and they’re not standard across public gyms. That’s driven a lot of people toward sauna blankets — infrared-powered wraps that promise the same sweat session without the hot room.
Going Deeper: Sauna blankets use far-infrared light to heat your body. Infrared saunas in general have shown real promise — a meta-analysis found they improved cardiac function in heart failure patients. However, long-term studies linking sauna use to longevity were all conducted with traditional Finnish saunas — not infrared or other types of heat therapy. Evidence for infrared saunas and blankets is still limited, and Mayo Clinic says deeper research is still needed.
Takeaway: Sauna blankets can increase your heart rate and make you sweat — mimicking some of the physiological effects of traditional saunas. If access or budget is the barrier, they’re a solid alternative, but not a perfect swap.
Bottom Line: A good sweat is typically a win, but more research is needed on the benefits of infrared sauna blankets before we cozy up in them in lieu of their classic Finnish counterparts.
