I have been reading this site for over a year and started taking cold showers (CS) right after. this info may help. first I take my CS at 5am i set my alarm and wake up every morning just for my CS. after i go back to bed to warm up. i do this because after some time in bed my body is warm all over. no cold hands, feet, other body parts. next i do as many pushups as i can. i think this is very important the body core temp up and makes the CS much more easy to take this gets my hart and breathing rate up. Just before this i turn the shower to full hot. after exercise i turn the shower to cool and get in and soap up. after 30 seconds i turn it colder then another 30 and turn it full cold. i try to stay in the coldest water for 5-8 minuets. i turn alot to get front and back. in winter my water gets down to 53f.
I wish more people would say what water temp they use. I seem to be more into this in winter than other times.
a few times i want the water to be even colder so i will take in a bucket of ice or snow water and after my CS i will pore it over myself as i lie in the tub. one more thing, i would like to know about others but for me i find i must have a high sex drive for this after sex i am not in the mood for a CS for 2-3 days then i am good until i have sex. i am 55. i live in a very cold area and the CS helps me deal with the cold weather.
