Hi, my question is I excersise almost daily, when I dont my heart rate stays normal but when I do exercise way after Im done I go to sleep and my heart beat goes up and wakes me up 2 o 3 hours later after, and the heart rate wont slow down, What is causing this?
Heart is a dynamic organ, so heart rate would increase or decrease according to bodies need of oxygen.  When you exercise the need of oxygen increases and so your heart rate will increase, which is a natural phenomenon.  Also, during sleep if you are stressed out, or you had a bad Chat Doctor.  You need to cut the cycle by relaxing as continued anxiety after getting up won't allow the heart rate to come back to normal. Al seems normal with your heart. Regards
