| Travel and Recreation Articles | Jet Lag -- New Approaches to an Old Problem -- Eliot C. Heher, MD |
| Although the ease of international travel has increased, jet lag remains a common problem. A study by The Upjohn Company reported that 94% of long-haul travelers experience it, while another survey found that 9 out of 10 flight attendants complain of jet lag, despite their familiarity with international travel. The symptoms are well known: fatigue, insomnia and poor concentration. Your performance can also be at risk. It is known, for example, that professional football teams have a worse record on the road when they cross multiple time zones compared with away games in their same time zone. Travelers often report that they're exhausted but can't sleep--truly one of life's most frustrating experiences. Jet Lag typically arises when you travel through three or more time zones. Complete recovery can take 3 to 7 days for westward travel, and 5 to 14 days after an eastward flight. Our bodies have internal clocks (circadian rhythms) which control many functions--including the sleep-wake cycle. Ever notice how you wake up a couple of minutes before your alarm clock rings--or you wake up at your usual 6 am even on Saturday when you'd hoped to sleep in? That's your internal clock. The key to dealing with jet lag is to reset your internal clock, the same way you reset your watch when the pilot announces the local time. Travelers with critically important meetings or events should arrive several days or more ahead of time to acclimate. Because eastbound flights are more difficult as the day is shortened, eastbound travelers should allow more recovery time. If possible, travelers should avoid "red eye" or night flights. On the night prior to any long haul flight, travelers should try to sleep as much as possible and attempt to arrive close to bedtime in the new destination. While there is genuine progress being made in understanding our biological clocks and in devising methods of resetting them, there is no miracle cure for jet lag. Here's my take on the specific methods you might consider: Light. Our internal clocks adjust based on daylight and many jet lag researchers believe the key to resetting the clock is to get out into the daylight. The best thing about this approach is that it can't hurt--and you'll get some exercise as well. Bear in mind that light must be bright to help you adjust--standard indoor lighting is unlikely to make any difference. In addition, light helps more if you are exposed to it at a certain time of day. Travelers who fly east to west should seek sunlight in the late afternoon. Travelers who fly overnight from west to east should do so during the mid to late morning. Diet. Long haul travelers often consume alcohol on flights in the belief that it will help them sleep. In fact alcohol prevents restorative REM sleep, and the traveler will wake up feeling tired. Alcohol in higher doses interrupts the circadian rhythm and interferes with acclimating to a new time zone. Alcohol also acts as a diuretic and in combination with the very dry air on airplanes can lead to dehydration which will intensify jet lag. (It is important to drink a large amount of water when flying). There is a diet known as the Argonne laboratories anti-jet lag diet which prescribes a feast-fast routine of high protein and carbohydrate foods along with specifically timed doses of caffeine. The diet has been designed for pilots or passengers crossing multiple time zones and has also been used successfully by military personnel. Additional information can be obtained by calling 1-630-252-5575 (press 4) or on the web at www.anl.gov. Medication. Ambien and Sonata are two relatively new, prescription sleeping pills that are popular for preventing and treating jet lag. Many travelers have also successfully used Benadryl and other over-the-counter antihistamines that cause drowsiness (Sudafed and other agents containing pseudephedrine should be avoided). Medications work by helping flyers sleep--so they're particularly useful on west to east overnight flights. Of course the drawback is that these are real medications with real side effects and how you react might be different from the way other travelers react. Be careful with the dose--some travelers report trouble waking up the next morning and others fear that the medications might interfere with their ability to evacuate a plane during an emergency. Benzodiazepine (or valium-like) agents should be avoided as there have been cases in which travelers who have taken them, especially Halcion (generic name: triazolam), have arrived at their destinations confused and disoriented, suffering from short periods of amnesia. It's always a good idea to limit use of any agent to three days or so. It's also a good idea to talk to your doctor about these medications, particularly if you have a chronic health condition. Melatonin. Melatonin is a naturally occurring hormone that is produced in the brain by the pineal gland and has been linked to the control of circadian rhythms. Melatonin is available as an over-the-counter dietary supplement in the U.S. and Singapore. Because dietary supplements are not regulated by the Food and Drug Administration (FDA), the composition of a pill labeled Melatonin may vary from manufacturer to manufacturer--even from batch to batch. In Canada, Australia and the EU, pharmacies dispense Melatonin only with a doctor's prescription because of concerns over uncontrolled self-prescribing, possible impurities and long term safety issues. While some studies published over the last ten years suggest that melatonin may treat jet lag, there is continued debate about the amount and timing of the dose. Some travelers report side effects--nausea and mild depression. My feeling is that more extensive research is needed to determine the value of melatonin as a jet lag remedy--and the agent itself needs to be manufactured in a more reliable manner. Other treatments. Popular suggestions for combating jet lag include special diets, trips to the spa, massages, sensory deprivation flotation tanks, topical creams and acupressure, among others. There are also a number of homeopathic remedies made from herbs and other ingredients. NADH (Trade Name Enadalert) was jet lag fad several years ago and has been the subject of some rudimentary scientific studies. My advice here is to use common sense. The evidence supporting the use of these methods and agents is thin to non-existent (i.e. studies are fairly small and the conclusions subject to additional research). You should be hesitant to actually ingest an unknown compound to treat jet lag which you know will eventually go away. Then again, if the treatment can't hurt (a massage, a spa trip), why not? You are likely to be less affected by jet lag if you do something to combat it--regardless of what you do. That's the placebo effect and it's a good thing to put to work for you. |
| A Mindful Road Trip: The Perfect No-Goal Vacation By Maya Talisman Frost It's the beginning of spring break, and we're heading south. That's all we know. Our family is greatly anticipating what may be our last road trip for a long, long time. There's a lot of excitement in our house right now as we are shifting into a whole new phase for each of us. My husband is launching a new business. I am writing a book. Our 17-year-old daughter is preparing for college in Nova Scotia in September. Our 16-year-old daughter is heading to Brazil for a year-long Rotary Exchange in July. Our 14-year-old daughter is playing a sport for the first time in her life. Our 13-year-old daughter is considering transferring to an arts magnet school in order to immerse herself in her passion—dance. This is the end of an era. In a few months, we will never have all four of them living at home again. The next year will bring all kinds of changes, and we feel we need to grab this chance to hit the road together in our trusty, dusty minivan. It's time for our favorite kind of vacation—the make-it-up-as-you-go meander through undiscovered (to us, anyway) territory. We'll get up really early, jump in the van, and just go. No reservations. No schedule. No destination in mind. We love this no-goal travel. We learned years ago that the happiest times we spend together are those in which we are free to experience each moment as it comes without planning the next. Back in 1998, we decided in one day to pack up the kids and take off to India and Nepal for three months. It's not as though we simply quit our jobs and left. That would have been far easier. We had plenty of responsibilities—we owned two small retail businesses, an import/export company, an old commercial building with a leaky roof, and a house we had just finished remodeling. We felt restless and ready for adventure, and making the choice to go was instantaneous and unanimous. We sold one business, liquidated another, put the third in a coma. We found someone to take care of the leaky roof, and another to stay in our house. We yanked the kids out of school and within six weeks of making our decision boarded a plane—six excited travelers carrying six small backpacks. The girls were 7, 8, 10 and 11. People thought we were insane. The first two months we spent in India visiting the former host families my husband had lived with during his own Rotary Exchange when he was 16. The third month we had reserved for Nepal. We planned to fly into Kathmandu and spend four weeks on our own. We had no agenda, no reservations, no contacts. We weren't the least bit concerned about it. From the very first day, it was clear this was going to be a really special experience for our family. We found a clean, friendly hotel, the Red Planet, with a room big enough for six of us. It was $15 a night. Our window faced the rear of a nightclub, and we giggled ourselves to sleep as Pink Floyd and Michael Jackson were blasted from the speakers outside. One of our daughters became quite adept at unclogging the toilet and bathtub drain. We wandered the curving streets, marveling at the sights and sounds. Each meal was an adventure as we made it a point to invite single diners to join us. We met fascinating people of all ages from around the world. Highlights include dashing into a tiny Italian restaurant during our first two hours in Kathmandu as we were caught in a torrential downpour—our first rain since leaving Oregon. A hilarious but fairly sleepless night sharing a tea house room with rats. Children, especially young boys, trailing us everywhere we trekked. Breakfast on our roof with a breathtaking view of the Annapurnas. Ducking to avoid spider webs dripping with dew while riding elephants in the early morning. Exploring richly scented temples. Spontaneous dancing in the streets. We have never, ever laughed more than we did on that trip. I had to use an asthma inhaler—not for any allergies, but because I laughed so hard that I started wheezing! Every single day was full of absolute joy and discovery. It didn't matter in the slightest what we were doing. We were together, we were exploring, and we were having the time of our lives. Granted, a road trip to southern Oregon isn't nearly as exotic. Still, what we learned in Nepal is the magic of being in the moment. Our kids discovered the power of being present and open to whatever the day may bring. It's a priceless lesson we feel fortunate to have learned early. That trip was a gift that keeps on giving. It provided a shining example of true mindfulness for our growing daughters. We're heading south. Our intention? To be together. To explore. And to laugh our heads off. I'll bring my inhaler. Maya Talisman Frost is a mind masseuse in Portland, Oregon.
