5 Tips For Battling Jet Lag

Jet lag is a common sleep disorder. It affects those who travel both frequently and infrequently. We spoke to Amy Korn-Reavis, R.R.T., R.S.T., a registered respiratory therapist and sleep technologist in Orlando, for one approach to the medical problems you or your loved one may suffer from when trying to sleep.

Jet lag is a circadian rhythm disorder, or a disorder that affects the body's internal clock. Travelers passing through two or more time zones often experience jet leg, but it can also affect those traveling through just one or two. It occurs because our location has changed clocks but our body hasn't, says Korn-Reavis.

Plan Ahead

Adjust your sleeping schedule a few days ahead of your travel date, if possible. By anticipating your new location's clock, your body will have more time to adjust and you won't suffer from jet lag, explains Korn-Reavis.

Avoid Heavy Eating And Drinking

Eating or drinking heavily will interfere with your ability to sleep. Korn-Reavis advises that you eat regular meals in appropriate portion sizes, but avoid binging prior to and during your trip if you don't want to suffer from jet lag.

Use A Light Therapy Box

If you're traveling a great distance and need to be alert shortly after arrival, invest in a tool like a light therapy box, advises Korn-Reavis. It helps combat jet lag. Use the box for 20 to 40 minutes either in the evening or in the morning, depending on whether you want to delay or advance your sleeping time.

Exercise Prior To And During Your Trip

Exercise both energizes you and helps you sleep better at night, thus eliminating jet lag. Exercise early in the morning to invigorate your body and stay active throughout the day. Not only will you be alert in the day, but come nighttime you'll fall asleep faster and sleep harder, Korn-Reavis says.

Take Naps

If you feel sleepy once in your new location, take a brief 15- to 30-minute nap. The nap allows your body to rest and you'll experience a boost of energy once awake, negating the effects of jet lag.
