How can sleep affect my blood sugar levels?

Dawn Marcus
Your body carefully regulates your blood glucose levels while you sleep, so you don't experience a drop in blood sugar levels even though you've fasted for 7 or 8 hours. If you lay down for 7 or 8 hours, don't eat, and stay awake, your blood sugar levels will drop. While you sleep, your body carefully adjusts sugar levels, changing your metabolism when you're in light and deep stages of sleep. Sleep restriction harms your body's natural ability to properly regulate blood sugar levels. Changes in metabolic hormones in people who have chronic sleep deprivation may result in increased risk for insulin resistance and diabetes.
