Take a Nap
A 10- to 20-minute catnap, according to experts, can boost your energy. If you are not sleeping at least six hours per night, you may be sleep deprived, which means hormonal havoc for leptin, gherlin and your cortisol levels. These hormonal imbalances result in sluggish behavior, craving sweets and low energy. Just make sure you set the alarm so you don't sleep more than 10 to 20 minutes. Experts agree that longer doses of napping can have the opposite effect.
