THE PRESIDENT & OTHER JET LAG SUFFERERS NEED LIGHT

 THE PRESIDENT & OTHER JET LAG SUFFERERS NEED LIGHT
 ROCKVILLE, Md., Jan. 9 /PRNewswire/ -- Jet lag sufferers and


problem sleepers are in for a bright surprise. Researchers have found that bright light entering the eyes resets the body's internal timing system in the brain, which can reduce jet lag symptoms, help adjust the shift worker to a new schedule and correct sleep disorders.
 Travelers who cross time zones simply can't adjust their body clocks quickly to a new schedule. Ninety percent of these people are affected by jet lag symptoms -- indigestion, moodiness, decreased mental and physical performance and the inability to sleep at night -- some of the same symptoms President Bush experienced in Asia.
 Recent research indicates that the human body clock, which tells us when to wake up and when to sleep, is extremely sensitive to bright light and darkness. Normally, body temperature, hormone production and other biological functions fluctuate according to a regular pattern over a 24-hour cycle. Such "circadian" rhythms govern many aspects of human metabolism, including the timing of sleep, wakefulness and attentiveness. Dr. Charles Czeisler, head of the Laboratory for Circadian and Sleep Disorders Medicine at Harvard's Brigham and Women's Hospital, using bright light 10 times brighter than an average room for just three days, successfully inverted the body clocks of NASA's space shuttle astronauts a full 12 hours. Crew member Robert Parker said, "When we started our shift we felt like it was morning, even though it was really the middle of the night."
 Phototherapy, carefully timed bright light, has become an accepted and recommended alternative to prescription drugs for many people to correct jet lag symptoms, assist shift works and correct sleep disorders. The SunBox Company was founded in 1985 to provide artificial bright-light devices called SunBox lightboxes for those who suffer from these disorders. New products this year include a lightweight battery-powered Light Visor and sunUp, a dawn/dusk simulator which one user reports, "I now have control over my own sunrise and can mirror the gentle awakening of sunlight with my bedroom lights anytime without being wrenched awake by my alarm clock."
 In the United States, almost 40 million people are involved in shift work, an estimated 24-37 million have sleep disorders and millions more travel each day. Sixty percent of those who work at night have dozed off or fallen sound asleep on the job, according to studies done on shift workers. Shift workers experience a significant loss of alertness and ability to make decisions -- a direct result of an imbalance in their body clocks -- which results in an increased number of errors and accidents. Yet many people in positions of great responsibility (hospital, police and fire personnel, equipment workers, airline personnel, etc.) have shift schedules. Some scientists believe that the 1979 accident at Three Mile Island nuclear power plant may have been partially due to the shift schedule of the crew on duty.
 The SunBox Company's products have been successful in:
 -- Helping to recycle the circadian system before departure so the traveler arrives at the destination already synchronized to local time.
 -- Resetting the sleep cycle, thereby relieving some forms of insomnia and increasing daytime alertness and energy.
 -- Altering the body's temperature rhythm and changing the timing, length and quality of sleep.
 -- Aiding those whose wake-sleep cycles are out of sync with the light-dark cycle.
 Today, Neal Owens, president of The SunBox Company, said, "We have made a commitment to help people improve their lighting environment so they can live happier, healthier lives." In an effort to fulfill that commitment, The SunBox Company has taken many steps, such as a short-term rental program, a toll free number for customer support, and periodic updates on light research in its free newsletter, SunNet News, available quarterly for those who wish to be included on its mailing list.
