Use Light Therapy to Combat Jet Lag

The timing of light signals can be as important as how much light we receive. When the biological clock receives light signals at the wrong time of day, it can become out of sync with the real world, creating havoc with sleep patterns, digestion and other activities. This phenomenon, called “circadian dysrthmia,” is most often experienced in “jet lag” – another condition that responds well to carefully timed use of bright light technology.

Scientific research has shown that light at specific times during your body’s circadian cycle sets your clock Eastward and at other times, Westward. So the key is to seek bright light at the correct time and avoid sunlight at specific times. The timing is crucial. Light at the wrong time during a trip to Europe could send your sleep patterns to Hawaii! BioBrite offers the easy-to-use Jet Lag Combat Kit (with Light Visor) (#88200) and booklet “Preventing Jet Lag,” which tells you exactly how to use light to rapidly shift your biological clock to the new time zone. Any bright light source which is not standard room lighting will work, particularly the sun, but since light may be needed at night or on the plane, the Light Visor in the Jet Lag Combat Kit is the only practical choice.

By the same token, our other Light Visors and light boxes can help with certain sleep disorders which require the reset of circadian rhythms. Look for our upcoming entry concerning these sleep disorders on your friend lists and community posts!
