After a few weeks in Asia and traveling long distances across several time zones in an Airplane I suffered from Jet lag.
Jet lag is where the circadian rhythm or internal body clock that regulates the 24 hour cycle of the biological process has be altered.
What are some ways to help with jet lag? Drink plenty of water when flying. Staying hydrated is essential Too much caffeine or alcohol can make you dehydrated. Wear sunglasses or an eye cover when trying to sleep on a plane. Avoid sleeping pills as that does not help and may hurt the biological clock.
What I like to tell my patients is to start taking 3-6 mg of melatonin a day before flying and the day of the flight. You may need to continue for several days after you return home. Melatonin is so good for helping adjust the internal clock.
I also recommend melatonin for shift workers that have their circadian rhythm altered.
Getting jet lag under control is important for people with sleep apnea because it just makes the condition worse and the patient more agitated.
