Explain the health benefits of infrared saunas

Infrared saunas have several health benefits, as discussed on the Huberman Lab. Here are some of the key points Andrew Huberman and Rhonda Patrick have mentioned regarding infrared saunas:

1. Cardiovascular Health:

   • Infrared saunas can be beneficial for cardiovascular health, improving conditions related to the heart. Sessions in infrared saunas have been shown to positively impact coronary heart disease and other heart-related conditions (1).

2. Sweat and Detoxification:

   • Sweating in infrared saunas can help excrete heavy metals like cadmium, lead, and aluminum, which are beneficial for detoxification (1).

3. Hormone Effects:

   • Sauna use, including infrared saunas, can promote hormonal changes. These may include increases in growth hormone and reductions in cortisol, contributing to stress management and recovery after physical training (2).

4. Immune System Activation:

   • Sauna sessions can activate the innate immune system by increasing leukocyte count. This may help keep colds and flus at bay, suggesting that regular sauna use could bolster immune function (3).

However, it's important to note that there are differences between infrared saunas and traditional ones:

• Infrared saunas usually operate at lower temperatures (around 140 degrees Fahrenheit) compared to studies on traditional saunas (about 174 degrees Fahrenheit). Thus, one may need to stay in an infrared sauna longer to achieve similar health benefits as those observed in hotter traditional saunas (1).

• While infrared saunas may offer these health benefits, Andrew Huberman has indicated a preference for stronger heat stimuli and the benefits associated with higher temperatures, which are often not achieved in infrared saunas. He also cited benefits of red and infrared light for wound healing, acne, and skin but clarified that the whole-body illumination offered by infrared saunas may not provide the same targeted effects as direct illumination onto the skin (4).

Finally, individuals interested in using a sauna should always consider their health status, existing medical conditions, and consult healthcare professionals. Safety practices should be observed during sauna use to avoid overexposure and potential risks.
