Cold Showers & Cryotherapy! Wake up!
While you may think a cold shower would stop your heart outright, it actually improves its function. The cold water increases blood circulation which is needed for growth and repair of vessels. Plus, better circulation improves the ability to circulate the things in your body that you need, i.e. hormones, oxygen, and nutrients. On the flip side it also works to flush out what you don’t want hanging around, like CO2 and tissue damaging toxins.
