I am 56 I and pretty active use to do HIIT 3 or more times a week for years and havent been last 5 months.. just working around the house.. I have had horrible sleep patterns for years, I found out my cortisol levels were high at night and early in the morning hence the bad sleep pattern.. Plus menopause.. so according to everything I have read working out for that long ( hour a day hard core ) is not good as after 30-40 mins it raises your cortisol levels.. That being said I also read that fasting when you have high cortisol isnt good as that also raises the levels.. I love to do intermittent fast..But have stopped as I am afraid now that will raise the levels.. Any insight??
