Huberman Lab Clips(@HLPClips):How cold your cold plunge actually needs to be: There's no number. It depends on your cold tolerance and core metabolism, which nobody can prescribe for you. The rule of thumb: get into water that's uncomfortably cold, where you want to get out but know you can stay in safely. That point shifts across the day. Your internal temperature is low early, rises into the afternoon, drops at night, so a cold shower at 11pm takes far more willpower than one in the afternoon. Jumping into a frozen lake untrained can cause cold shock and kill you. @hubermanlab
