One of the world's most well-known self-help speakers, Tony Robbins also partakes in the cold plunge and he combines it with a sauna session. According to Insider, the change in your physical and emotional state that takes place during his process has to do with hormones — and Robbins is a big fan. By first sitting in a hot sauna for a few minutes, he reaps the benefits of heat shock proteins, human growth hormone and others that have a variety of health benefits. Plus, it may also help reduce symptoms of anxiety while increasing one's ability to focus.

From here, the cold water takes it a step further. Speeding up the heart rate and constricting your blood vessels while releasing adrenaline and endorphins, this process can feel amazing. It's also worth noting that moving from extreme heat to extreme cold can be dangerous for those with heart issues and other medical concerns, so check with your doctor before participating. 

Of course, Tony Robbins credits his practice with a few mental health benefits that keep him on his game. The outlet quotes him as saying his hot-cold routine "improves circulation and wakes your a** up," while noting that the cold plunge "trains the mind to not hesitate but to act."

If you're still not sold, try turning your water heat down at the end of your shower. Take a few moments to breathe and feel the cold, then see how you feel. You may notice a clearer mind, an awakened body and a general feeling of wellbeing.
