I’ve heard so much hype about the cold plunge and have recently been taking cold showers but decided I wanted to take the plunge. The internet tells me that an ideal cold plunge temperature is around 50 degrees and that your average bathtub can get as cold as 50 degrees, so I did the obvious thing. After filling my bathtub as cold as it goes, I set up my red light device, set a two minute timer, and hopped in. I took a sharp breath in through my nose and then a longer, slower breath out my mouth. The general idea I found online is to make your exhale longer than your inhale. This promotes relaxation. I played around with multiple short inhales and some breath holding. I also dunked my head under after I a few breaths.
The cold bath was super intense at first but by the end of my two minute timer I was feeling the rush and enjoying it. It definitely gave me the brain boost that the internet suggests it does. I’ll certainly be doing more of this. If you have a bathtub, then go give this a shot.
