Infrared Saunas

Sliced Bread

Available for over a year

Are infrared saunas as effective as traditional ones? If you've ever sat sweating on a wooden bench in a traditional ('Finnish') sauna wondering if there was an easier way, could infrared be the answer? Infrared saunas work at lower temperatures, ostensibly making it easier to stay in there for longer. Listener Paul got in touch after trying one and wants to know if infrared saunas give you the same purported benefits as traditional ones. Those claims include: improved cardiovascular health, weight loss, longevity and even benefits to mental health and depression. But what's the evidence and does it amount to a load of hot air? To get the answers, Greg Foot is joined by Professor Chris Minson, an expert in the effects of heat on the body who's carried out research on infrared saunas.
