Richard Beever’s 2009 review article looks at the health benefits of far-infrared saunas (FIRS), a type of sauna that uses infrared heat to warm the body directly. This type of sauna is different from traditional ones because it doesn’t heat the air as much, which some people find more comfortable. The review examines studies that explore how FIRS might help with things like high blood pressure, heart disease, and chronic pain. The evidence shows that FIRS can be beneficial for people with heart problems, especially those with heart failure, helping to improve heart function and reduce symptoms. It also seems to help lower blood pressure and improve blood vessel function. However, there isn’t strong evidence to support claims that it can help with weight loss or lower cholesterol levels.
Overall, while there is some good evidence that FIRS may help with heart health and reduce symptoms for people with chronic pain or high blood pressure, the research is still limited. Many of the studies are small, short, and not always perfect. For example, while FIRS might improve heart function and symptoms in people with heart failure, it hasn’t been shown to lower cholesterol or triglycerides, despite some claims from sauna manufacturers. The review suggests that FIRS is a safe treatment for certain conditions, but more studies are needed to fully understand its benefits and how well it works.
