Infrared vs traditional saunas: key differences explained

Short answer: The core difference between infrared and traditional saunas lies in their heating method and the maturity of the scientific evidence supporting them. Traditional saunas use convection to heat…

How infrared saunas work: heat, light, and tissue interaction

Short answer: An infrared sauna works by using specific wavelengths of light to create heat directly within your body’s tissues. Unlike traditional saunas that heat the air around you, infrared…

What is an infrared sauna? (mechanisms, wavelengths, and physiological effects)

Short answer: An infrared sauna uses radiant heat from infrared light emitters to warm the body directly, rather than heating ambient air like traditional saunas. Operating at 120-150°F (compared to…

What is a low-emf infrared sauna? (measurements, mechanisms, and verification)

Short answer: A low-EMF infrared sauna minimizes electromagnetic field exposure from heaters and wiring, typically achieving readings below 3 milligauss (mG) for magnetic fields and under 5 volts per meter…

What happens to your body in a sauna? (physiology explained)

When you sit in a sauna, heat exposure raises core temperature, increases heart rate, widens blood vessels, and activates sweating as the body works to regulate temperature. This places a…

Do sauna suits work? The science behind sweat, performance, and what you really lose

Sauna suits can work, but not for the reason most people buy them. While they are ineffective for sustainable fat loss, their true, science-backed purpose is to serve as a…

How an infrared sauna helps back pain by targeting the source, not just the symptoms

An infrared sauna helps alleviate back pain by using radiant heat to penetrate deep into muscle and soft tissue. This deep heat promotes significant vasodilation (widening of blood vessels), which…

Why sweating happens in a sauna: cardiovascular effects and what it means for your health

Intentional sweating in a sauna creates measurable cardiovascular responses in the body. The heat exposure elevates your heart rate and promotes blood vessel dilation through a process called thermoregulation. While…

How many calories do you burn in a sauna? a complete guide for your body type

Some estimates suggest a 30-minute sauna session may register several hundred calories of energy expenditure—but these numbers are often misunderstood. The real question isn’t how many calories you burn, but…
