Have you ever wondered which wellness tool fits best into your routine: infrared saunas or red light therapy? These two increasingly popular therapies promise transformative benefits, from pain relief and better skin health to mental clarity. While both harness light to enhance your well-being, they work in distinct ways.
In this article, we’ll break down the unique advantages of infrared heat versus red light, from pain relief and detoxification to skin rejuvenation and cellular repair. Whether you’re looking to boost muscle recovery, enhance skin health, or simply unwind, we’ll help you choose the right therapy—or explore how both can complement your wellness journey.
Infrared saunas and red light therapy are wellness treatment innovations designed to improve overall health, but they operate in distinct ways.
Infrared saunas utilize infrared heat to penetrate the skin, raising the body’s core temperature at a lower temperature compared to traditional saunas. This generates a deep, soothing warmth. The two types of infrared saunas are far-infrared and full spectrum, which offers near, mid, and far infrared light therapy. This type of sauna emits infrared light to deliver radiant heat, which encourages sweating without the intense heat of conventional saunas.
Red light therapy exposes your skin to red and near-infrared light, allowing the light to reach deep into the tissues [4]. This process boosts the production of adenosine triphosphate (ATP), the main source of cell energy, helping to optimize cellular performance and support tissue repair. By boosting the cells’ energy production, red light promotes tissue repair, subsides inflammation, and speeds up wound healing. Unlike infrared saunas, red light therapy does not rely on heat but uses light energy.
Infrared sauna therapy and red light therapy serve distinct functions in enhancing wellness. The key difference lies in their mechanisms: infrared saunas focus on sweat induction through heat exposure, while red light therapy delivers localized light therapy without significant temperature changes.
Infrared saunas utilize infrared waves to penetrate the skin and raise the core body temperature. This heat triggers sweating, which supports many of the benefits you can get from infrared saunas. We’ll share more about these benefits in the next sections.
Red light therapy, in contrast, emits specific wavelengths of light in the visible spectrum and near-infrared wavelengths. These light waves get deep into the skin and tissues to stimulate cellular function by increasing adenosine triphosphate (ATP) production. Unlike infrared saunas, red light therapy does not cause sweating but directly targets cellular repair and tissue regeneration.
Usage differences between the two also reflect their unique impacts. Infrared saunas are typically used for whole-body benefits, as we will see when we talk about the unique benefits of infrared saunas. A typical session lasts between 20 to 40 minutes, with the heat gradually building to induce sweating.
The experience is akin to traditional sauna therapy but at a lower temperature, making it more tolerable for extended periods. These saunas are particularly suited for those looking to relax and improve overall cardiovascular and metabolic health.
Red light therapy, on the other hand, is a more targeted treatment. It’s commonly delivered through red light therapy devices like panels, handheld devices, or beds. Sessions usually last 10 to 20 minutes, focusing on specific areas of the body, such as the face for skin rejuvenation or muscles for pain relief and recovery. The lack of heat makes red light therapy ideal for individuals who prefer non-invasive, localized treatments without the sweating or cardiovascular effects of saunas.
To further differentiate them, let’s find out the benefits that are unique to infrared sauna and red light therapy.
Infrared saunas promote detoxification by inducing deep sweating, which helps eliminate toxins such as heavy metals, environmental chemicals, and other impurities from the body [2]. The infrared heat penetrates deeper than traditional saunas, encouraging the body to expel harmful substances through sweat. Research has also shown that using an infrared sauna can effectively aid in reducing toxin loads, particularly in individuals exposed to pollutants.
Infrared therapy is well-documented for its ability to alleviate muscle and joint pain [3]. The heat increases blood circulation, delivering oxygen and nutrients to affected tissues while reducing inflammation. For conditions like arthritis and muscle stiffness, regular use of infrared saunas can provide long-lasting relief. Research highlights its effectiveness in managing chronic pain and enhancing mobility through regular use.
Infrared saunas promote vascular health by increasing blood flow. As the infrared heat warms the body, it causes the blood vessels to expand, improving circulation and lowering blood pressure. This effect supports cardiovascular health and helps deliver nutrients to muscles, enhancing recovery especially when using a sauna post-workout.
The heat from infrared saunas triggers the release of endorphins, the well-known "feel-good" hormones of the body, which can greatly help reduce stress and improve overall mood. Additionally, infrared therapy relaxes muscles and calms the nervous system, aiding in better sleep quality. Research indicates that consistent use of infrared saunas can help regulate the body's stress response, leading to improved mental clarity and relaxation.
Infrared saunas are highly beneficial for improving skin clarity and elasticity. The heat boosts collagen production and promotes detoxification through sweat, reducing the appearance of fine lines, wrinkles, and acne. Infrared therapy has been found to enhance cellular regeneration, aiding in a smoother, more youthful skin texture. Studies support its use in managing skin conditions and improving skin tone.
Red light therapy boosts collagen production, improving skin elasticity and firmness [1]. It helps reduce wrinkles, scars, and fine lines by energizing cells with ATP to repair and renew. Over time, it enhances skin tone and texture, tackling issues like acne, hyperpigmentation, and sun damage. Regular use leaves your skin healthier, more radiant, and glowing with proven benefits for overall skin health.
Red light therapy can help ease chronic pain and accelerate tissue repair. By boosting blood flow to affected areas, it reduces inflammation while delivering oxygen and nutrients to damaged tissues. This makes it particularly effective for individuals with conditions like arthritis, tendonitis, or post-injury recovery. Moreover, it promotes faster muscle repair and reduces soreness, making it a popular choice for athletes and those recovering from injuries.
Regular exposure to red light therapy has been shown to boost mental health by influencing the production of serotonin and reducing stress-related cortisol levels. These changes contribute to a more balanced emotional state and a reduction in symptoms of depression and anxiety. Studies also indicate that red light therapy improves sleep patterns, which further enhances its mood-boosting effects.
Red light therapy stimulates the hair follicles, encouraging them to grow. This boosts blood flow towards the scalp and increases energy production in cells, which helps in keeping your hair healthy. Studies show that with consistent use, red light therapy can help restore hair density and improve the overall strength of strands, making it an excellent option for those experiencing hair thinning and those who have conditions such as androgenetic alopecia.
Red light therapy speeds up wound healing by enhancing tissue regeneration and reducing inflammation at the injury area. This is achieved by stimulating cellular energy production, which supports the repair of damaged tissues and promotes cell formation. Studies have found it beneficial in treating various types of wounds, including ulcers, surgical incisions, and burns. Additionally, red light therapy reduces scarring risk by improving the skin’s healing response.
When deciding between an infrared sauna or red light therapy, consider your primary wellness goals. Here are some tips:
Both therapies are generally safe but require precautions. Infrared saunas are not recommended for people with cardiovascular conditions, heat intolerance, or high blood pressure, as the heat can exacerbate these conditions. Pregnant individuals or those with chronic health conditions should also consult their healthcare provider before use.
Red light therapy is non-invasive but should not be overused, as excessive exposure could cause mild skin irritation. Consulting with a healthcare professional is advised if you have pre-existing medical conditions or are pregnant. Perform a patch test before starting therapy if you have sensitive skin or are prone to photosensitivity, as red light can occasionally cause irritation.
Using both therapies can offer a holistic approach to wellness. For example, combining the detoxification and circulation benefits of an infrared sauna with the targeted tissue repair of red light therapy can optimize recovery post-workout. Additionally, pairing the skin health benefits of red light therapy with the stress-relief properties of infrared saunas enhances overall relaxation.
Consider both therapies if you’re addressing chronic pain, as the infrared sauna’s heat relieves soreness, while red light reduces inflammation in specific areas. Similarly, individuals recovering from injuries may benefit from red light therapy’s localized healing effects, complemented by the whole-body relaxation of an infrared sauna.
To incorporate infrared sauna therapy, start with the recommended duration of 15-20 minutes, gradually increasing to 30–40 minutes as your body acclimates to the heat. Use the sauna 2–4 times per week, ensuring you stay hydrated before, during, and after each session. Pair sauna use with relaxing activities, such as meditation, to enhance the stress-relief benefits.
For red light therapy, target specific areas for 10–20 minutes per session, 3–5 times per week, depending on your wellness goals. Devices like panels or handheld units are ideal for home use, and sessions can be easily integrated into your skincare or recovery routine. For optimal results, use therapy consistently and on clean, dry skin.
Infrared saunas are better for whole-body pain relief by improving circulation and reducing muscle soreness with heat. Red light therapy works best for localized pain by reducing inflammation and promoting tissue repair.
Infrared saunas are typically used 2–4 times per week for 20–40 minutes per session. Red light therapy can be used 3–5 times per week for 10–20 minutes per session, depending on the area and device intensity.
Red light therapy is generally safer as it doesn’t involve heat, reducing risks like dehydration. Both are safe when used appropriately, but individuals with pre-existing conditions should check with a healthcare provider before use.
Infrared saunas and red light therapy each offer unique wellness benefits, from detoxification and pain relief to improved skin health and mood enhancement. Infrared saunas use heat to promote deep relaxation, cardiovascular health, and whole-body recovery, while red light therapy focuses on targeted cellular repair and skin rejuvenation without heat. By understanding their differences and aligning them with your goals—whether stress relief, enhanced recovery, or improved skin—you can make an informed choice.
