If you are already sleep deprived – meaning you get less than 8 hours of sleep (and I need 8 hours to feel completely rested) and you also have little time for exercise….which would be better health-wise: getting an hour less sleep and getting in some exercise? Or getting the sleep?
This would be for some one who is relatively healthy – meaning no health issues and no weight issues.
Why are you getting less than 8 hours of sleep? If you lay in bed for hours on end but can’t sleep then I’d say get some exercise — it will help alleviate the anxiety and stress that is keeping you awake. OTOH, if you’re going full-tilt until midnight and have to get up at 6 in order to do it all again the next day then carving out an hour for exercise is only going to add to your stress.
Based on this, I’d say you’d benefit more from extra sleep.
You walk several times a day, can you add in another 10 or 15 minutes over lunch?
How about when you go to the rest room, instead of going right back to the office, you take a brisk walk up and down the hall?
Smokers take a smoke break, you’re entitled to a walk break.
Is there any time in your day/week that is just time? Does your morning dog walk allow you to step back from the stress of life or are you just hoping he’ll hurry up and do his business so you can get ready for work?
Exercise should be you time. The walks to and from the parking lot certainly count as exercise, but I don’t see those as times when you’re not tuned in to work/obligations. When do you get time?
