Intended use The goLITE BLU energy light is intended to make people feel more energetic, to adjust circadian rhythms and to provide mood relief from the winter blues. The medical intended use of the goLITE BLUE energy light is to treat winter depression (seasonal affective disorder). [. . . ] - If mornings or evenings do not seem to be the problem, but you feel generally tired during the day, then the time at which you use the goLITE BLU energy light is not as important. You can use the goLITE BLU energy light in the morning or around midday. For example, when you wake up in the morning, use it for fifteen to thirty minutes and then again at midday or in the evening for approximately the same amount of time. Place the goLITE BLU energy light further away from you during the evening treatment. This keeps your body clock from confusing the stronger morning signal with evening time. Do not use the goLITE BLU energy light within two hours of your desired bedtime. Blue light can suppress the nighttime hormones for a while, and you may not be able to fall asleep. Winter depression If your seasonal mood swings are more severe and you are suffering from depression, you should consult a specialist and only use light therapy in consultation with this specialist. Your specialist may prescribe 45 minutes of treatment per day at level 1 or 2 over several weeks. Section `Sleep and energy' above contains some general guidelines for the timing of light Expose, but this timing should also be determined in consultation with your specialist. Jet lag Rapidly travelling across several time zones creates disharmony between your internal body clock and the new external time. This not only causes sleeping problems, but influences your mood and energy level as well. If you stay for more than a few days, you may also want to shift your body clock to the new time zone. This will help you sleep better and be more alert and energetic when you need to. Because special blue light is effective for shifting circadian rhythms, your goLITE BLU energy light can quickly adjust your rhythm to the new time zone. One of the best strategies to combat jet lag is to shift your body clock a day or two before you leave. Travelling east: When you travel east , start using the goLITE BLU energy light in the morning two to three days before you leave. The number of time zones you travel corresponds to the hours your body clock has to shift. If you are only travelling a few time zones, one day's preparation is sufficient. Add a day of light therapy for each additional 2 time zones. For example, for a trip from the US to Europe, use the following schedule: On the first day, wake up an hour early and use the goLITE BLU energy light for 30­45 minutes. On the next day or days, you should wake up a couple of hours earlier and repeat this process. [. . . ] You can use the goLITE BLU energy light daily, especially during the winter months. Many people find that they do not need the light in summer. Others use it year-round because they spend most of their time indoors and do not get the right kind of light signals to regulate their circadian rhythm properly. The light is safe to be used around children and pets. [. . . ]
