How to Stay Awake Naturally

9. Switch Tasks to Stimulate Your Mind

In 2004 Finnish researchers who studied people working 12-hour night shifts found that monotonous work is as harmful as sleep loss for alertness. At work or home, try to reserve more stimulating tasks for your sleepy times. Or switch to more engaging work responsibilities when you feel yourself nodding off. 

10. Drink Water to Prevent Tiredness

Dehydration can cause fatigue. Make sure you drink plenty of fluids and eat foods high in water such as fruits and vegetables.

11. Get Some Daylight to Regulate Your Sleep Cycles

Our circadian rhythms, which regulate our sleep-wake cycle, are influenced by daylight. Try to spend at least 30 minutes a day outside in natural sunlight. (Sleep experts recommend an hour of morning sunlight a day if you have insomnia.) Even a step outside for a breath of fresh air will revive your senses.

12. Exercise to Increase Energy and Reduce Fatigue

In an analysis of 70 studies involving more than 6,800 people, University of Georgia researchers found that exercise was more effective in increasing energy and reducing daytime fatigue than some medications used to treat sleep problems. Regular exercise also improves quality of sleep.

Try to exercise 30 minutes a day. If you decide to exercise hard some days, your energy level may drop for a bit and then surge for a few hours. Eating a meal that contains both protein and carbohydrates within two hours after a heavy workout will lessen the initial energy loss. Be sure to finish your workout a few hours before bedtime so you are not energized when you try to sleep.

When to See a Doctor About Your Sleepiness

If you find that you can’t stop nodding off when you need to be alert, consult a doctor or sleep specialist. You may have an underlying sleep disorder such as excessive sleepiness or narcolepsy, which can be treated. Your doctor may prescribe medications to help you with a sleep disorder. If you have trouble falling asleep because of stress or other reasons, cognitive behavioral therapy can help you develop good sleep habits and relieve sleep anxieties.
