How to Beat Jet Lag, According to Sleep scientists
Jet lag can nearly ruin a trip and totally throw you off. Fortunately, sleep researchers have found ways to make jet lag less terrible. The key is that the body's sleep cycle naturally responds to certain environmental cues, and you can take advantage of that to shift your sleep cycle accordingly. Full story: http://bit.ly/1YwliRd
- 1.Make sure you're well-rested before travelingYou're probably going to lose some sleep while traveling, so you may as well start off in a good place. No reason to add extra sleep deprivation on top of jet lag. And how do you know if you're sleep-deprived in the first place? If you regularly fall asleep within five minutes of lying down, that's a sign of sleep deprivation (or a sleep disorder), according to the National Institute of Neurological Disorders and Stroke.
- 2.For longer trips, adjust your body's clock a bit ahead of timeIf you're planning to be in your new time zone for a while, you can start the adjustment process before you even leave home. Start going to bed and getting up a little later or earlier, depending which direction you're traveling. (For those traveling west, go to bed and get up a bit later. For those traveling east, do the opposite.) And shift your light exposure accordingly, too. Seek out bright light when it would be daytime at your destination. Avoid it when it would be nighttime there.
- 3.Drink plenty of water on the planeResearchers recommend drinking plenty of water before and during your flight (and avoiding dehydrating alcoholic and caffeinated beverages), walking around during flights to improve circulation (and the amount of oxygen getting to your brain), and possibly taking an aspirin the day before and the day of your journey (which should also improve circulation).
- 4.For short trips, it might not be worth trying to fight jet lagYour body takes several days to adjust to a new sleep schedule. So if you're just going somewhere for a few days, consider trying not to adjust to the new time zone, says Colwell. This will make coming back much easier. You can do that by tweaking your light exposure.
- 5.For longer trips, use light to adjust to the new time zoneIf you're trying to adjust to a new time zone, get lots of light during daylight hours, especially in the mornings. Remember that outdoor light is generally better for retraining your brain — it's brighter than indoor light (even on a cloudy day). And limit light exposure near bedtime, including from computers and televisions.
- 6.Adjust your eating and exercising, tooSome research has shown in mice that eating causes changes in insulin levels, which in turn influence the body's timekeeping. So try to adjust your meals to wherever you are. For example, if you normally eat breakfast at 8 am in New York, eat breakfast at 8 am in London, too. The same goes for exercise, Colwell says. After all, your body probably isn't used to you exercising in the middle of the night. So, in general, do these activities at whatever hours you're trying to tell your body is dayt
- 7.Melatonin might helpMelatonin is the hormone that your brain generates that makes you sleepy. It's sold over-the-counter at most pharmacies. Because the US government regulates melatonin as a dietary supplement and not a drug, the FDA hasn't approved it as something that can treat any particular condition. However, a Cochrane review of nine medical studies found that participants who took 0.5 mg to 5 mg of melatonin right before bed reported fewer jet lag symptoms, compared to those who took a placebo pill.
- 8.Be careful with caffeineAlthough you may be tempted to guzzle coffee or soda to stay alert, consuming caffeine later in the day may keep you up at night. Caffeine has a half-life of six hours in the body, which means that it takes six hours for your body to get rid of just half the caffeine you've consumed. So be careful with drinking caffeinated beverages in the afternoon, especially if you've just flown from west to east.
