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). This treatment should only take place in consultation with a specialist.

Light, health and circadian rhythms

The human body uses light cues, such as those provided by the sun, to time certain internal functions. Properly timed rhythms regulate mood, sleep, energy, appetite and digestion. These daily internal cycles, called circadian rhythms, sometimes fall out of sync, resulting in a dysregulated body clock. Unfortunately, modern living has dramatically altered nature's cues.

A modern day no longer starts at the crack of dawn and ends at 8:00 p.m. Workdays are getting longer and many people face shift-work schedules. Additionally, the advent of electric lighting allows social gatherings and personal activities to extend well into the night. These factors have diminished the body's natural ability to regulate the body clock.

Rapid travelling across time zones is another source of disharmony between the internal clock and the external time, which is referred to as jet lag. Proper timing of bright light exposure allows quick adjustment to the new time zone.

Besides regulating the body clock, light has direct alerting and energising effects and improves our performance. Bright light therapy is also successfully used for mood relief, especially for seasonal mood swings. In countries with long winters, many people experience loss of energy and low spirits due to lack of light. These symptoms are referred to as the winter blues. They typically start in autumn and may last for several weeks. Exposure to bright light sources can help alleviate these symptoms and restore the summer mood and summer energy level.

Research shows that a special photo receptor in our eyes is responsible for regulating our energy and sleep/wake cycles. This receptor responds to the

blue light of the summer sky. We do not get as much of this light in the autumn and winter, and indoor light does not emit enough of this essential colour. The goLITE BLU energy light helps to shift circadian rhythms back to their normal pattern by delivering the wavelength, colour and intensity of light that our body responds most efficiently to. The goLITE BLU energy light naturally improves your mood and energy levels by a relatively low light intensity compared to traditional white light therapy devices.

Preparing for use

When to use the goLITE BLU energy light

Knowing what time to use the goLITE BLU energy light can mean the difference between feeling better in just a few days instead of weeks, or perhaps not responding at all. Follow these guidelines to understand how light affects your body clock and when to use the goLITE BLU energy light for the best results.

Duration and intensity

Most people get beneficial results from 15 to 30 minutes of usage each day. You can start using the goLITE BLU energy light at medium intensity and increase the light intensity if you feel no response after a week.

Sleep and energy

Using the goLITE BLU energy light at any time of day directly affects your alertness. You can use the goLITE BLU energy light as light therapy for the winter blues throughout the day. The best time to use it is in the morning. Do not use the goLITE BLU energy light late in the evening. If you use it within 2 hours of going to bed, it could disrupt your sleep.

• If you find it difficult to get up each day without an alarm clock or if you often sleep in, you need morning light. Use the goLITE BLU energy light within the first hour or two after waking up.
• If you find it difficult to stay awake in the late evening and wake up too early in the morning, you need evening light. Use the goLITE BLU energy light before you start to feel drowsy.
• 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.

ENGLISH12

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 30–45 minutes. On the next day or days, you should wake up a couple of hours earlier and repeat this process. You should advance your bedtime accordingly. Once you arrive at your destination, avoid light before 10 a.m. local time (wear sunglasses) and use the goLITE BLU energy light in the midmorning to fully adjust to the local time. When returning, use your goLITE BLU energy light in the late evening for a couple of nights before the return flight. On the last night of the trip, try to stay up and use your goLITE BLU energy light as late as reasonably possible past midnight. On the day of the flight, avoid any bright light until after 2:00 p.m. (see below under 'Travelling west')

Travelling west: Since most people's body clocks adjust more easily to later time zones, you should not have to use the goLITE BLU energy light when you travel 3 time zones or less. You should only need to use your goLITE BLU energy light for one day before travelling 4 time zones, and add an additional preparation day for each 3 time zones. You should not have to use the goLITE BLU energy light for more than 3 days, even on the longer westbound trips. For example, when travelling from London to Los Angeles, use your goLITE BLU energy light for 30–40 minutes in the late evening (and again a couple of hours later, if you can) each night, starting 2-3 days before you leave. Use the goLITE BLU energy light 2-3 hours later each successive night. When you arrive at your destination, try to stay awake until bedtime and avoid bright evening light (wear sunglasses) for the first few days. Before you travel home, avoid any bright afternoon and evening light and use your goLITE BLU energy light in the morning for a few days (see above under ‘Travelling east’).
