Engage in regular aerobic exercise. Again, we don't know for sure if exercise helps people with SAD, but some evidence suggests that it does. Aim to exercise outdoors in the early morning hours. Try walking, jogging, biking, swimming. Even better, exercise in the sun or near a sunny window.
You can also keep your body's clock in sync by rising and retiring at the same time each day, even on weekends or days off from work. When you can't get going no matter what you do, try sucking on some ice. Its chill can give you a wake-up call. Or, splash your face and wrists with ice water.
Another option is to steep peppermint or lemon oil in water and inhale. These are stimulating oils and may give you a little extra zip.
