What you are saying is wrong. I am supplementing since 0.5 month off, I supplement over 10 things. I take a regular walks of 4-5mile or more which can be considered light exercise. I was doing heavy exercising for 3months during my recover and fasting for 2 months with 12h no food intervals. I'm doing seemen retention too, big streaks. I'm doing lot of mental exercising. I was doing wimhof method for 1 month. I was doing 9C cold showers for 1 month and now I'm back to it but now I just don't shower my backs and it gives me no issues only benefits. Will start wimhof again but don't go too hard with it because it can irritate your lungs.
