Saunas and cold plunge pools are increasingly popular across the UK, appearing on beaches, city farms, and parks. Enthusiasts tout benefits for both mind and body, but what does the evidence actually show?
In a recent podcast, Ian Sample and Dr Heather Massey, an associate professor at the University of Portsmouth's extreme environments laboratory, discussed the scientific basis for these claims. Dr Massey noted that while many users report feeling invigorated, the research on cold water immersion is mixed, with some studies suggesting potential benefits for circulation and mood, but others highlighting risks like hypothermia.
For saunas, evidence is stronger: regular use has been linked to improved cardiovascular health and reduced stress. However, experts caution that individual responses vary, and both practices should be approached with care, especially for those with underlying health conditions.
