The Easiest Way To Hack Hot & Cold Therapy Without A Sauna, From An MD 

If you've found yourself here, you're likely already familiar with the benefits of hot and cold therapy: It aids cellular energy, improves resilience, and promotes detoxification (just to name a few highlights). And while it sounds high-tech, you don't actually need any fancy gadgets to dabble in the practice. Sure, you could invest in a proper cold plunge tub, or you can just turn the nozzle to freezing during the last 30 seconds of your shower. Ta-da! 

The "hot" portion, however, is a bit trickier to dupe. You don't want to turn the faucet to the opposite extreme, as a scalding shower can easily burn your skin. You could opt for a portable sauna, but, well, those can get expensive.

"If you can't afford a sauna, exercise is great," she shares on the mindbodygreen podcast. Better yet, it's completely free! "You need to invest time in exercise, but going out for a run will get you sweating and your body temperature up, and that is a great way to actually get the lymph flowing." 

Especially if you're after the detoxification benefits of sauna, exercise does provide a worthy alternative. You see, your lymphatic system doesn't have a "pump," unlike your circulatory system. Moving your body stimulates this lymphatic system, which basically acts like a giant drainage system for your body. "So if you don't move your body, the fluid in the lymph is stagnant. It doesn't move, so now toxins are not moving to where they should be, and you are not detoxifying," Chen adds. 

Not to mention, Chen notes, sweating can help you eliminate heavy metals and contaminants, like phthalates1 and BPA2. "So you are sweating out toxins, no matter how you sweat," she explains.
