I am on vacation right now and just taking off and getting away is doing wonders for me. However we do have access to a hot tub and I have been sitting it in daily. I have noticed that 1 year ago with high cortisol and actually all my life I could sit in a hot tub for a very long time with no ill effects. Now I can't do past 15 minutes or I feel week and have to take a cold shower and rest for about 1 hour. After the hour I was fine but everyone is different.
