Is infrared sauna safe?

Infrared saunas are generally safe for healthy adults and have a favorable safety profile compared to traditional saunas due to their lower operating air temperatures (120 to 150 degrees F versus 150 to 190 degrees F). The primary risks are dehydration and heat-related issues like dizziness or light-headedness, which are easily prevented with proper hydration and session length management. However, several populations should exercise caution or avoid infrared sauna use entirely. People with cardiovascular conditions including uncontrolled hypertension, unstable angina, or recent heart attack should consult their cardiologist before use, as the heat stress increases heart rate and can affect blood pressure. Pregnant women should avoid infrared sauna due to the risk of core body temperature elevation, which has been associated with neural tube defects in early pregnancy. People taking medications that impair sweating or heat regulation — including beta-blockers, diuretics, and antihistamines — should consult their physician. Those with active skin conditions, open wounds, or recent surgical sites in the treatment area should wait until healed. Individuals with multiple sclerosis may experience temporary symptom worsening with heat exposure. Always stay hydrated, exit immediately if you feel dizzy, nauseous, or confused, and avoid using the sauna under the influence of alcohol or sedating medications.
