I understand that cardiovascular exercise raises the body temperature immediately, making it harder to sleep at the moment. But then, after 5 hours, your body temperature falls below what it was right before you started exercising, making it easier to sleep.
Therefore, when I want to sleep at 10 PM, it's good to finish 20-30 minutes of exercise by 5 PM.
But if 5 PM slips by and I haven't exercised, have I lost all chance of utilizing this mechanism? Or are there some changes I can make to the activity I would have done that will result in my body cooling itself off faster?
