The Science

Hot and Cold Therapy has been around for a long time. Evidence of cave saunas dating back to 2000 BC have been claimed, however their use would have been more for surviving freezing temperatures than relaxation. Saunas these days are usually associated with Finland. Despite a population of just over 5 million people, Finland has an impressive 3 million saunas to share between them — far outnumbering their cars — while ‘Finnish saunas’ are now found in gyms and spas almost everywhere on Earth. To this day, newer research is frequently supporting their numerous and undeniable health benefits

Ice baths have most likely been around for much longer as no special structure is needed – all it takes is a winter dip in a frozen lake or flowing river. Running hot water is a relatively new luxury on the scale of things, only becoming available to the public within the past two hundred years – bathing in cold water would have been the only option for most up until this point. The Edwin Smith Surgical Papyrus is one of the oldest surviving medical texts created in the 1600 B.C. This text made numerous references to the use of cold as therapy.B
