Sunshine on the Back of Your Knees

It’s summer.

For some, this might involve a long trip across many time zones. Perhaps even to geography halfway around the world.

Because of our overseas lifestyle, I have been flying internationally at least twice a year for the past 30 years. In the beginning, I ignored the concept of jet lag and simply acclimated with a lot of sleeping. It was easy to fall asleep on planes. When the engines revved up and white noise began, I closed the window shade and REM sleep took over. After reaching destination, I slept some more. Eventually, day and night realigned.

Numerous tips have been written about preventing or overcoming jet lag. Some are helpful.

Suggestions such as a good night’s sleep before a long flight, over-hydrating by consuming more water than you want, and refraining from too much alcohol or caffeine. Other tips include not flying with a hangover [major hydration no-no] and immediately adopting the day/night schedule of your destination geography.

These days jet engines don’t automatically make me pass out, so I think about waking/sleeping hours on a plane differently. I diligently perform ankle circles and spinal twists in my seat. I get up to walk or stand. I drink many glasses of water. I take brief naps rather than sleep for hours at a time. All are decent behaviors for trying to align my body clock. But they never accomplish the whole thing.

Recently, I made a long flight from Paris to Singapore and Bali and back to Europe two weeks later. Sixteen hours of flight time each way with six hours of time difference.

The friend who travelled with me to a yoga retreat in Bali had two jet lag ideas that were completely new. The first came from a limited study done in 1998. It was quirky enough I wanted to believe its’ conclusion–exposing the back of your knees to light, particularly sunlight, in the first days after travel, alleviates jet lag.

An instant antidote! And perfectly timed as we had two recovery days in a hotel in Denpasar before the retreat began. Our base of operation was established immediately after breakfast in poolside lounge chairs. When knees overheated [front or back], we obligingly cooled them by sliding into the water. If boredom or cloud cover made it silly to continue this “therapy”, we went exploring.

The other new jet lag treatment was more medically aligned with the body’s circadian rhythms. It was the result of a hormone study by my friend’s physician brother on human cortisol fluctuation.

I emailed him after the trip to ask more about it. Dr. John replied, “Jet lag is hormone dislocation.” Translation: The body’s normal clock gets out of whack when you pass through multiple time zones.

“Your cortisol level surges each day at awakening. It is set to your biological clock and changes only reluctantly–about one hour per day per time zone. Hence the lag.”

At the opposite end of the day, when it’s time to go to bed, the brain produces melatonin and off to sleep we go. Cortisol levels rise again with the sun. The cycle continues.

Big time zone changes mixed with fluctuating biorhythms can play out dramatically in young children. Our son was six-years-old the first time we flew home to the U.S. after moving to Singapore. During an early dinner, we watched his head suddenly sag forward and plop down in the center of his plate. Sound asleep in mashed potatoes.

Dr. John suggests: “The fix [to jet lag] is in replacing the hormone [cortisol] at the right time of day. Hydrocortisone is safe and effective when you take it at 7:00AM local time for just three days. You can’t do it everyday, only with international travel. Combine that with melatonin [3-10mg] to help get you to sleep and you get the benefit both ways. Works like a charm.”

Take 20mg Hydrocortisone for three days only, at 7 AM local time, for international travel.

You need a medical prescription for oral cortisone and it may be challenging to find a physician willing to write one for jet lag, even in such a limited dose. You could try encouraging your physician with what Dr. John says: “Simple replacement dose is not the same as a treatment dose of prednisone which overpowers your own cortisol. It’s safe and effective.”

I have yet to use cortisone therapy for jet lag. Instead, I researched that back-of-the-knees-light-study from the ‘90s. It was debunked, not long afterward, as nonsense.

After returning from Bali I took 45 minutes each afternoon for a week to lie on the floor by my dining room window and expose the back of my knees to sunlight. When I really wanted a jet lagging nap, I found that sunny-knee-time seemed to warm up my brain and nourish it, too. I was more alert, avoided the nap, and slept through the night.

Fact or fiction, back-of-the-knee sun exposure worked for me.

Regardless of this or that tip for recalibrating your body clock, you can just live out jet lag and do nothing. Eventually, day and night cycles return to “normal” wherever you are.

However, try to avoid falling asleep at the dinner table. Or try to finish your meal first so as not to wake up in a pool of gravy.
