Concerns about the safety of infrared saunas continue to be raised, despite the fact that they’ve been around for quite some time and many people continue to use them. Common inquiries include: Is frequent exposure to infrared or EMF dangerous? Or can sauna use actually be dangerous to people?
The answer to the first question is no. Much of the public’s fear about infrared possibly stems from the cited dangers of ultraviolet rays (which are harmful). However, infrared is a different light spectrum altogether, and it doesn’t share the same danger as UV rays. The only known negative effect it can give is sunburn, but this only happens when the person exceeds the recommended use (about 60 minutes per session at VERY high temperatures).
In terms of EMF or electromagnetic field, they also pose no danger. In fact almost anything around us emits EMF (sun, cellular phones, etc.), and they have been deemed not harmful to people. If you’re still skeptic however, you can opt to buy a no EMF infrared sauna.
Regarding the second question, sauna use can be dangerous to some people with certain health conditions like multiple sclerosis and systematic lupus. Sauna use is also discouraged for pregnant and intoxicated people, but is however generally safe and even beneficial to the health of most. Some studies have even suggested that frequent sauna use can improve blood circulation and increase stamina.
