FAQ & DETAILS:
1. "What is the history of light therapy?"
Light therapy, or phototherapy,
the science behind The Tireless Traveler "sunlight prescription,"
was first used to treat sleep disorders and seasonal affective disorder
(SAD). In 1984, Dr. A.J. Lewy and Dr. Serge Daan applied their carefully
researched techniques to the phenomenon of jet lag and discovered
that light therapy was just as effective in treating this problem.
Subsequent research by others confirmed the efficacy. Correctly
timed sunlight exposure, as a remedy for jet lag, was how light
therapy was first tested and confirmed in the field.
"What is melatonin?"
in 1959, melatonin is a sleep-inducing hormone secreted by the pineal
gland, a tiny endocrine gland situated at the center of the brain.
Your body's natural production of melatonin is increased by darkness
and suppressed by sunlight. Among other things, melatonin decreases
brain-wave activity, causes drowsiness and prepares the body clock
for sleep. Tests with prescribed melatonin have been promising,
but even in the best situations the body clock was not altered any
faster than using light therapy. Your Tireless Traveler sunlight
therapy formula will influence your body's melatonin production
schedule to synchronize with your new surroundings.
"Can I use my "sunlight prescription" if I have existing
you have chronic sleep problems light therapy for your trip may
not be an effective jet lag therapy because your body clock is out
of sync. Medications can also affect the success of this treatment.
Diabetics and anyone on medication timed to body rhythms should
not use this therapy.
4. "Do I have to stay
in direct sunlight?"
We are not suggesting that you lay on the beach for six hours. Walking
the streets of a market town, sitting in the sunny window of a café,
or reading underneath an umbrella will suffice. Even a cloudy day
provides enough sunlight. However, wearing sunglasses will likely
interfere with the success of the therapy.
5. "Will man-made
Man-made light is less intense than sunlight and typically does
not influence melatonin production. In most indoor situations you
will not get enough light to influence your body clock to change.
However, resting in a dimly lit room with the curtains drawn is
recommended for the indoor portion of your sunlight schedule.
"Won't I get over the feeling of jet lag on my own in a few days?"
not. Your body clock is your internal mechanism that regulates,
among other things, metabolism, blood pressure, body temperature
cycles, hormone secretions, and melatonin production. The smooth
timing of these physiological functions influences your sleep patterns,
concentration, moods, reflexes, and energy level--things you typically
don't notice until they're out of sync. Left on its own, your body
clock will adjust itself about an hour each day. If you cross seven
time zones, your body clock needs about seven days to completely
adjust. Researchers estimate that 70% of international travelers
are negatively affected by jet lag. No one knows exactly why some
travelers seem to be unaffected by the problem.
"I usually start to feel better after about the third or fourth
day into a trip to Europe. Why would I want a "sunlight prescription?"
Instead of starting to feel better after about the third or fourth
day, your body will be adjusted by the third day without the lingering
symptoms you're tolerating now.
for Tireless Travelers:
You, the modern jet traveler, are, in a manner of speaking, a time
traveler. Leaping time zones in a single day, you enjoy a freedom
unknown to your ancestors of just a few generations ago. However,
you pay a price for this freedom in the havoc visited upon your
body by the abrupt disorientation of having days and nights at the
about wildly in the days before leaving on a trip seems to be de
rigueur. Typically, this means sleeping schedules change, too,
and that is not a good thing. Getting up earlier and sleeping less
works against you.
should you do while on a long and tiresome journey in the air? While
on board you need to take care of yourself by resting whenever you
can, eating small snacks of protein and complex carbohydrates, drinking
plenty of refreshing water, and moving about or exercising at regular
intervals. You should avoid alcohol and caffeine, too. Then, with
a user-friendly body poised for success and only minimally abused
by travel fatigue, begin following your "sunlight prescription"
when you arrive at your destination.
are variables that affect the success of the formula--that's the
bad news--but many of them are under your control--that's the good
news. For our part we can merely provide you a safe, natural, effective
therapy for overcoming jet lag and hope that the sun will shine
benevolently when you call for it. The rest is up to you, wise and
