Who Else Wants Permanent Relief From Jet Lag... Before Your Plain Even Lands!

and 5 a. Jetlag is actually caused by disruption of your 'body clock', a small cluster of brain cells that controls the timing of biological functions (circadian rhythms), including when you eat and sleep. Exposure to light at the wrong time can actually make jetlag worse. So patients with asthma often have more bronchoconstriction and more difficulty with their asthma during the night when airway function fluctuates to compensate for sleep. m. ) And the World Health Organization links jet lag with travelers' lowered resistance to infections such as those that cause diarrhea.

* Don't use sleeping pills: A report in England's Lancet medical journal blames 18 percent of long-haul deaths on blood clots to the lungs — and sleeping pills induce a comatose state with little natural body movement (thus reducing circulation, thus increasing the chance of clotting). Also, individual susceptibility tends to vary considerably and it is possible that pre-existing sleep deprivation will intensify jet lag. Martin Moore-Ede, professor at Harvard Medical School, recommends you expose yourself to bright daylight, without sunglasses, for at least fifteen minutes as soon as you can. Consult your physician. When, for example, bright light stimulates the optic nerves, the optic nerves send the signal to the suprachiasmatic nucleus, which then triggers circadian rhythms, resulting in the synchronization of the body's 24-hour cycle with the earth's 24 hour cycle. The exact length of the cycle is not known and is probably slightly longer than 24 hours, perhaps 24. Travelers who sleep normally prior to transmeridian travel are not immune to jet lag; the symptoms result when a persons internal clock attempts to acclimate to a new external environment. The symptoms of jetlag often persist for days as the internal body clock slowly adjusts to the new time zone. The symptoms of this circadian-rhythm disruption are well known: exhaustion, headache, and dehydration (dry eyes, throat, nose, even skin), disorientation, anxiety, indigestion — even impaired coordination — all, according to NASA, requiring roughly a day of recovery for every time zone you crossed.
study showed that age and flying at night may exacerbate jet lag. Flying east usually results in difficulty initiating sleep, where as flying west results in early morning awakenings. Jet lag (desynchronosis) occurs while rapidly crossing time zones, or, more specifically, it occurs after crossing the Earths meridians. Martin Moore-Ede, professor at Harvard Medical School, recommends you expose yourself to bright daylight, without sunglasses, for at least fifteen minutes as soon as you can. Besides taking good care of yourself, other harmless ideas abound: walk barefoot on the ground at your destination; swim in the ocean; or take an Epsom-salt bath (all reportedly to ground your electromagnetic system). Back to Top Signs and Symptoms In addition to the tired-wired, soar-crash feeling that travelers experience after long, rapid air travel, there are numerous symptoms that may occur with jet lag, such as insomnia, daytime fatigue, stomachaches, headaches, irritability, and decreased awareness. When, for example, bright light stimulates the optic nerves, the optic nerves send the signal to the suprachiasmatic nucleus, which then triggers circadian rhythms, resulting in the synchronization of the body's 24-hour cycle with the earth's 24 hour cycle. Circa is the Latin word for about, and diem is the Latin word for day. m.
For this reason, one can feel lethargic one moment and excited the next. Although jet lag occasionally lasts for a week or more, travelers usually return to their normal sleep-wake pattern after a day or two. Sometimes even quite long journeys will not cover many timezones, for instance South America/USA, South Africa/Europe. S. For many travelers, jet lag can catalyze the effects of certain conditions associated with the head and nervous system that are not related to specific sleep-wake patterns. The degree of disruption varies greatly among people; some may not be bothered at all. * Exercise and stretch — in your seat, in the aisles, and during stopovers (pilots swear by stopover showers, for circulation). All the rhythms mentioned above occur in humans within a cycle of approximately 24 hours. Charles F.

Jetlag is actually caused by disruption of your 'body clock', a small cluster of brain cells that controls the timing of biological functions (circadian rhythms), including when you eat and sleep. Some of these nerves feed the hypothalamus, a part of the brain that regulates body temperature, water and sugar ratios, and fluid secretions and which houses the suprachiasmatic nucleus, a bundle of nerves that controls the bodys circadian rhythms. Melatonin has also been proven in studies to reset the internal clock to nighttime, though it makes some people groggy upon waking and its long-term effects are unknown. and 5 a. and 3 p. Your computer might have a utility that shows timezones world-wide, for instance double-click on Windows clock. Most people have experienced the urge to fall asleep in the late afternoon, after eating lunch. Melatonin has also been proven in studies to reset the internal clock to nighttime, though it makes some people groggy upon waking and its long-term effects are unknown. (Vernon Ansdell, of the University of Hawaii, pointed out at a recent Wilderness Medical Society meeting that newer aircraft circulate more air.
Jet lag, or desynchronosis, is a temporary condition that some people experience following air travel across several time zones in a short period of time. This circadian tendency has serious ramifications in our society. 2. The book Overcoming Jet Lag, by Dr. Mental alertness and the propensity to fall asleep are regulated by circadian rhythm. That way I'm fresh for my true objective while others who killed time exploring in town are fading — or bailing — at the trailhead. For instance, body temperature slowly rises throughout the day, drops dramatically around midnight, and begins to rise again before 6 a. * To maximize rest time, go to sleep immediately — as soon as the plane pulls away from the terminal and cuts off fresh air until takeoff (a natural sleep-inducer). Because, after all, I can always be tired and cranky when I get home.
There are a disproportionate number of automobile accidents between 3 a. You've planned your trip so you won't waste a moment of your vacation hunting down headlamp batteries or stove fuel. * Don't wait for the in-flight drinks or meal — that could take hours; eat lightly if you do eat at all. And I use eye drops en route, and pound Emer'gen-C vitamin packets (found at health food stores) to rehydrate and replenish electrolytes. It is not necessarily the food that makes people want to fall asleep at this time, but the time of day. ) And the World Health Organization links jet lag with travelers' lowered resistance to infections such as those that cause diarrhea. There are a disproportionate number of automobile accidents between 3 a. m. Ehret and Lynne Waller Scanlon, calls for consuming caffeine and high-protein and high-carbohydrate meals at certain times of the day and in certain amounts, depending on the number of time zones you'll be crossing.
. Decreased vigilance can combine with sleepiness and result in an accident. 4. * Use earplugs, a blindfold, blanket, neck rest — whatever it takes. People naturally synchronize their internal clocks with day-night cycles, which allows them to be awake during the day and to sleep during the night. 7 to 25 hours. ' * Bring water on the plane and drink it (WATER — not tea, juice, coffee, soda, or alcohol). A successful time zone shift depends on knowing the exact times to seek and avoid bright light. Jet lag is the curse of modern jet travel, resulting in loss of working efficiency and holiday enjoyment, often for days after arrival.
