Jet Lag Symptoms Fever
Jet lag -> fatigue: Sleeping 14 hours is likely simple exhaustion and sleep deprivation. Although a few days of "jet lag" can surely cause both! Jet lag more typically causes tiredness, sometimes headache, nausea, poor focus, and that frustrating "can't fall asleep at bedtime / am wide awake at 4am" feeling. Hopefully a good sleep has started to reset your bio-clock! ...Read more
Several: I try to sleep on the plane as much as possible since you are missing sleep going east. But then it is hard to fall asleep on return since your body thinks its earlier. Try some melatonin, which is the body's rythym hormone. Keep the lights off at night to induce sleep and very bright in the as (i like a dawn simulator) avoid alcohol and drugs. ...Read more
Fatigue, mild nausea: Jet lag occurs when you travel east or westbound. Typically you feel fatigued, mild nausea, and have trouble with sleeping. It lasts a few days, often worse on the first day. Get out into sunlight and take melatonin if you are having trouble sleeping. ...Read more
Jet lag remedy: Jet lag is a disruption of circadian rhythm caused by traveling to different time zones. Basically adaption to the the local cycles of light and nutrition are the most effective means to adjust. If possible, a day or so before traveling, begin to change sleeping and eating times to those of the destination. Fasting for about 16 hours during travel and exposure to light also attenuates effects. ...Read more
Jet Lag results from: An imbalance in the body's natural "biological clock" caused by traveling to different time zones. The 24-hour cycle of "circadian rhythms" are measured by the distinct rise and fall of body temperature, certain hormone levels and other biological conditions, all influenced by our exposure to sunlight to determine when we sleep and when we wake. They adjust slowly after changing time zones. ...Read more

Light and dark: The best strategy for jet lag involves carefully controlling exposure to light and dark in order to help your brain's internal clock make the fastest adjstment possible to the new time zone.

Depends: Traveling eastward is typically worse than westward. It also depends on the number of time zones you are crossing. If you are just crossing one or two time zones, you may just want to live with it. Crossing more than two, if you have a week to prepare, you can start living based on your new time zone, adjusting one hour each day until you are living in your new time zone BEFORE you leave. Best. ...Read more
Sun & melatonin: Jet lag is the mismatch between your internal biologic clock and the external world. Your internal clock is set by sunlight, espeically morning and evening light as well as your body's natural sleep hormone-melatonin. Exposure to sunlight morning and evening and using melatoinin prior to sleep you can hasten your adaptaion. Jet lag causes decreased memory and analytic skills for the first few days. ...Read more
Increase Melatonin: Jet lag is a mismatch between your internal biologic clock and the external time of your surroundings. Your internal clock is set by both sunlight and melatonin. Get out into sunlight morning and evening, eat at times for new time zone, and take melatoinin before bedtime. Avoid computer & tv screens 4 hours before bed as they interfere with melatoinin production. Prescription sleep aides may help. ...Read more
Light exposure: There are many, many approaches to jet lag, however the approach that I think has the best evidence basis involves using light and dark exposure to shift your body's internal clock to the new time zone. British airways has a decent one on their website. For added effect you might try taking melatonin in the evening. ...Read more
Stay awake: The best strategy is to attempt to convert over to the "new time" by attempting to go to bed at a regular time, based upon the new time zone. ...Read more
Some of my friends get very sensitive to light when they suffer from jet lag? Is that possible? What can we do?
Jet lag brain edema:
Sleep deprivation prevents the brain from cleaning out toxic waste products. Mild brain edema may occur.
The eyes may become photosensitive to a mild degree.
Short naps may help but a full night's sleep is in order.
Pycnogenol or ginko biloba may help relieve the symptoms of jet lag. N-Acetyl Cysteine may also relieve stress on the brain. Follow the directions on the bottles. ...Read more
I have been back from traveling for a week now, but I still have jet lag and only get a couple hours of sleep. What can I do?
Reset required: The most important step in treatment is taking to stay up during the day, be exposed to sunlight, (esp in afternoon), avoid all stimulating substances (e.g. Caffeine) after mid-day, and make sure that no matter what time you actually fall asleep at, you wake up at the same time every day.

Despite effects of jet lag, is it also possible that during recovery, a person to experience dreams even in daytime naps? I would like that! :)
Can melatonin really help me get over jet lag faster? If so, how long before my transatlantic trip do I need to start taking it? Thanks so much.
Yes!: Melatonin levels in your body spike at bedtime, and the general advice is to try taking it when you want to fall asleep. Try 1-3 mg at bedtime the first night after you arrive in the new time zone to help induce sleep at what will seem an abnormal time to your body for sleeping. A rule of thumb is that it takes a day for each hour of change in time zone to fully acclimate to your new zone. ...Read more
Jet lag: You can try complex methods of putting yourself on the new time with meals and medications before travelling, or just stay up when you reach the new site until 10 pm and then go to sleep (even if it means taking a prescribed sleeping pill if it feels to early). Don't drink on the plane and stay hydrated. ...Read more
Change your schedule: If you are young, less than 30 or so, a few hours difference won't bother you much. Going west is less of an issue than heading back east. To prepare: go to bed 45-60 min later each night for few days before heading west or 45-60min earlier each night for few days before heading east. The further u travel, the more hours/days u need to change. Have fun wherever u r heading. Be safe and good luck. ...Read more
