Cold Shower

up:: Health & Fitness

Cold exposure, through a shower or better yet, an ice bath, is great for your health. It improve the immune response and lowers inflammation. Wim Hof

Cold exposure lowers your dopamine when you're in it (because you don't want to) but research has shown that after, it actually upregulates dopamine for multiple hours. Andrew Huberman

This is a great motivational tool: starting the day off showing yourself that yes, you can really push through and do something you don't want to do.
