Infrared saunas have gained popularity for their potential health benefits, including their positive effects on skin conditions. By improving skin hydration, strengthening the skin barrier, promoting circulation, and aiding detoxification, infrared sauna therapy may support overall skin health. Here’s what the research suggests:
1. Enhanced Skin Hydration and Barrier Function
Regular sauna use, including infrared saunas, can improve the skin’s ability to retain moisture and stabilise the epidermal barrier. A study by Kowatzki et al. (2008) found that individuals who frequently used saunas had increased stratum corneum hydration and a more stable epidermal barrier. This helps protect the skin from external irritants and reduces water loss, leading to healthier, more resilient skin.
2. Reduction in Skin Inflammation and Itching
Infrared sauna therapy has been linked to improvements in inflammatory skin conditions, such as psoriasis. Sauna bathing helps with the removal of hyperkeratotic scales, a common issue in psoriasis patients. Additionally, combining sauna use with moisturisers or topical treatments has been found to enhance treatment efficacy (Hannuksela & Väänänen, 1988). Those suffering from chronic itching or irritation may also experience relief due to the anti-inflammatory effects of heat therapy.
3. Improved Circulation and Oxygenation
Infrared sauna sessions can boost blood circulation, which plays a vital role in skin cell regeneration and healing. Improved microcirculation helps deliver essential nutrients and oxygen to the skin, promoting a brighter complexion, faster wound healing, and overall enhanced skin function (Sobczyk et al., 2021). This effect may benefit those dealing with eczema, rosacea, or dull skin.
4. Detoxification and Antimicrobial Effects
Sweating is one of the body's natural detoxification processes. The heat exposure in infrared saunas helps eliminate toxins and impurities through sweat, which may benefit individuals with acne, clogged pores, or other skin impurities. Additionally, the high temperatures in saunas have been shown to kill dermatophytes and other harmful microorganisms, potentially reducing the occurrence of skin infections (Hannuksela & Väänänen, 1988).
Conclusion
Infrared saunas may offer a range of benefits for skin hydration, inflammation reduction, improved circulation, and detoxification. This makes them a promising complementary therapy for skin conditions such as psoriasis, acne, and general skin health maintenance. However, individuals with sensitive skin or conditions like atopic dermatitis should consult a dermatologist before incorporating regular sauna use into their skincare routine.
