Are there any good cures for jetlag?

Asked by ben (8681points) June 16th, 2007

I have a friend who just got in from China and has been having severe jetlag, accompanied by nausea.

From personal experience, the nausea will fade after getting a good (3 to 4 hour) nap or a good night's sleep. Once the nausea has passed (usually the next day), try to avoid day-time naps (despite the sleepiness) so that exhaustion really sets in by the evenings. This way, your friend will have a better chance of sleeping through the night, which will help him/her adjust to the new timezone.

Yes there is indeed a cure, and its a wierd one but based on science and experience.

Shine a flashlight behind each of your knees for 10-15 minutes each. Apparently there exists some nerves back there that are photo-active from the good old days when rocks were the technology of choice.

I swear by it.

if he wants to get over the nausea and adjust to local time he should...
-not give in to napping during the day
-drink lots of water
-adjust to local time by getting outside and into sunlight
-eat during local mealtimes.
-get some exercise- even just walking a lot outside during the day will help
p.s. this site looks fantastic now!

Yes, the kneecap thing was published in Science (Campbell, S.S. et al. (1998) Extraocular circadian phototransduction in humans. Science, 279, 396-399.), but there was also a rebuttal to that, as the experiment was not able to be replicated by others (Wright, K.P. Jr. et al. (2002) Absence of circadian phase resetting in response to bright light behind the knees. Science, 297, 571.). Cool concept though!

The normalization of body rhythms to the local daylight regime takes different amounts of time, and sleep rhythms may adapt more quickly than temperature cycles, for example. I find melatonin (or even benadryl) to be a good soporific to induce sleep and Modafinil (Provigil) if available can help relieve grogginess in the morning until you adjust. cheers!

Works great and all natural! Gotta try the knees thing… sounds like an April Fools Day gag. Works best with foil hat.
