I workout every two days, I mostly do 45 minutes-workouts 'heavy-lifting' oriented (deadlifts, squats, bench press, weighted pull-ups, abs), and, each week, one of these workouts is more cardio-oriented.
I usually take cold showers each days at 7 PM, but I'm working out at 11 AM (or 4 PM for cardio days).
The thing is that I've read that cold and hot showers have various effects, but they are generally considered to be post-workouts. For instance, hot showers are supposed to help to build muscle while cold showers reduce inflamation, so muscle growth, but they reduce cortisol levels (so it improves testosterone level which is needed for muscle growth).
Do cold/hot showers still have an impact on muscle growth hours after a workout? If so, how should I adapt them? (For example: hot showers on workout days, cold showers on rest days)
