Hi, how are you going? It's day 11, and today we're talking about hot and cold therapy—saunas and ice baths. You might think these are just another wellness fad, but interestingly, these practices have been around since ancient times. Many traditions have stood the test of time because people have observed benefits. If something appears to work, people keep doing it! The good news is that you don’t have to be a top-level athlete to enjoy the benefits of hot or cold therapy—anyone can take advantage of them.
So, what does a sauna do? Well, it helps to "sweat out toxins," so to speak, but it also aids relaxation and stress relief. More importantly, saunas activate heat shock proteins—special proteins within muscle cells that alter metabolic pathways, making the cells more efficient under stress. If you think about it, the human body is an adaptive organism that responds to environmental stressors. When faced with heat, it adapts to become stronger.
Cold therapy works similarly. Cold exposure reduces inflammation and constricts blood vessels, but just as heat activates heat shock proteins, cold triggers cold shock proteins. Some people find that alternating between hot and cold exposure enhances their well-being. The idea is that exposing the body to controlled extremes toughens the physiology, potentially improving metabolism and even the immune response.
What can you do? If you're listening to this, there's a good chance you're aware of Younger Longer and the resources available there on hot and cold therapies—so be sure to check them out! But if you don’t have access to a sauna, you can try a hot bath for 10–15 minutes, as hot as you can tolerate, followed by a cold shower for a minute or two. This simple routine can give you a taste of the benefits of contrast therapy.
Hot and cold therapy is a great way to reap some of the benefits of exercise in a different form. It can be a solo practice or a social experience. In Finland, where much of the research on saunas has been conducted, regular sauna use has been linked to better cardiovascular health. Interestingly, saunas are often enjoyed in a social setting, adding a connection component to the practice.
I'm going to leave it there. Whether you’re running hot or cold on your shower tomorrow, I hope you’ve had a great day today. I wish you the very best—live as well as possible for as long as possible. I look forward to catching you tomorrow.
Take care, and bye for now!
