Is there a best time to exercise? The short answer is yes:
anytime you can fit it into your schedule. But exercise such as
walking and moderate aerobics brings down blood sugar both while
you do it and for up to a day afterward. While that’s the big
payoff, it’s also a potential hazard, especially if you take
medication or insulin. The reason? Let’s say you’ve just taken
oral medication or a dose of insulin to bring your blood sugar
down, and then you immediately walk for an hour. The glucose-
lowering combination of the treatment and the activity could
send your blood sugar crashing. On the other hand, if you’re
taking insulin but don’t give yourself a large enough dose, your
blood sugar may actually rise too high during exercise. That’s
because when you’re physically active, the liver pumps out more
glucose, and without adequate insulin, your body will have
trouble shifting glucose from your blood to working muscles.
Only you and your doctor can sort this all out, but you may be
