For instance, if you travel from California to New York, you “lose“ 3 hours according to yourbodys clock. You will feel tired when the alarm rings at 8 a.m. the next morning because, according to your bodys clock, it is still 5 a.m. It usually takes several days for your bodys cycles to adjust to the new time. To reduce the effects of jet lag, some doctors try to manipulate the biological clock with a technique called light therapy. They expose people to speciallights, many times brighter than ordinary household light, for several hours near the time the subjects want to wake up. This helps them reset their biological clocks and adjust to a new time zone.Symptoms much like jet lag are common in people who work nights or who perform shift work. Because these peoples work schedules are at odds with powerfulsleep-regulating cues like sunlight, they often become uncontrollably drowsy during work, and they may suffer insomnia or other problems when they try to sleep. Shift workers have an increased risk of heart problems, digestive disturbances, and emotional and mental problems, all of which may be related to their sleeping problems. The number and severity of workplace accidents also tend to increase during the night shift. Major industrial accidents attributed partly to errors made by fatigued night-shift workers include the Exxon Valdez oil spill and the Three Mile Island and Chernobyl nuclear power plant accidents. One study also found that medical interns working on the night shift are twice as likely as others to misinterpret hospital test records, which could endanger their patients. It may be possible toreduce shift-related fatigue by using bright lig hts in the workplace, minimizing shift changes, and taking scheduled naps.湖北中公金融人湖北中公金融人金融类考试培训的领跑者金融类考试培训的领跑者Many people with total blindness experience life-long sleeping problems because their retinas are unable to detect light. These people have a kind of permanent jet lag and periodic insomnia because their circadian rhythms follow their innate cycle rather than a 24-hour one. Daily supplements of melatonin may improve night-time sleep for such patients. However, since the high doses of melatonin found in most supplements can build up in the body, long-term use of this substance may create new problems. Because the potential side effects of melatonin supplements are still largely unknown, most experts discourage melatonin use by the general public.更多招聘信息动态、考试内容请关注：湖北银行招聘信息网更多信息请关注湖北银行招聘网：http:/hu.jinrongren.net/
