The benefits of cold showers are incredible. A cold shower can improve everything from your hair to your sperm count, your immune system to your metabolism. But during the summer months, there is yet another benefit that most people forget. If you’ve been working hard on your summer tan, you want to avoid hot showers and opt for luke warm or even cold showers. Hot showers increase skin cell removal and will shorten the life of your tan or your “spray on” tan. So get your chill on and keep your summer glow among other things!!
