> For now it's not clear why more exercise might make up for poor sleep One potential reason is dramatically lower cardio stress. I run about 3-4 miles 4-5 times a week through asthma. I can run through the asthma for a bit but it raises my pulse rate during exercise. Even better than running is long distance speed walking which burns calories just the same but keeps your pulse in your exercise target heart rate. The result is a resting heart rate of about 53 bpm for most of the rest of the day with excellent blood pressure. A couple years ago when I was fast (and far away from my asthma triggers) my resting heart rate was around 44bpm. Not bad for somebody in their 40s. Out of shape my resting heart rate is closer to low or mid 70s and my blood pressure is about 40 points higher. I also seem to achieve 20 pounds overweight. My heart has to work much harder during the day and I need better sleep to make up the difference. As a side note I have discovered the muscles that induce asthmatic symptoms fall off after about 45 minutes of continuous intense cardio. I suspect that’s how long it takes for those muscles to reach muscle failure and relax.
