The Comfort of Blue

By using BLUEWAVE light-emitting diodes (LEDs), the goLITE BLU delivers safe and effective wavelengths of light, while eliminating harmful UV and the eyestrain that can be associated with other bright light treatments.

Safe and Effective

According to independent ocular safety testing, BLUEWAVE light is safe when following the recommended usage guidelines. BLUEWAVE technology in your goLITE BLU passes ICNRIP/ACGIH threshold value limits at only 15% (light energy exceeding 100% is considered potentially hazardous). The effectiveness of the type of light in BLUEWAVE has been researched and advocated by leading medical universities. For more information, visit www.LightTherapy.com.

Understanding 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 an unregulated 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.

Circadian Rhythm Imbalance

When our circadian rhythm becomes imbalanced, the body produces the wrong hormones, chemicals, and neurotransmitters at the wrong time of the day. The results range from feelings of sadness to sleeplessness to lack of energy. Many people suffer from a loss of energy and mood that can last for a short period of time to more than a couple of weeks. For many, these feelings come on stronger in the winter and in darker climates.

An imbalance in circadian rhythms contributes to the following:

• Winter blues • Lack of energy (especially in the winter)
  • Feelings of sadness • Sleeplessness
• Jet lag
• Mood swings
• Lack of concentration • Irritability
• Loss of appetite

Restored Balance with BLUEWAVE Technology

BLUEWAVE technology helps shift circadian rhythms back to their normal pattern by delivering a specifically engineered wavelength, color, and intensity of light that stimulates the production of key substances triggered by the brain. BLUEWAVE naturally affects the body by shifting the body clock to its correct timing, causing the proper signals to be produced at the right time of day.

goLITE BLU Features

Using Your goLITE BLU

Plugging In Your goLITE BLU

Your goLITE BLU comes with a 9V AC/DC adapter with US-style prongs. Your adapter can operate on AC power ranging from 100–240 volts for usage worldwide. Use the enclosed adapter only. For safety and proper operation of your goLITE BLU, never use an unapproved adapter.

Charging Instructions

IMPORTANT: Charge your goLITE BLU for at least 8 hours before initial use.

The goLITE BLU contains an internal Lithium-Ion battery pack. To charge your goLITE BLU, connect your AC/DC adapter to a wall outlet and plug the goLITE BLU into the adapter. The battery display icon will show the outline only. As the battery charges, the four bars will blink one by one and fill in as the charge increases. Once the battery is charged, the battery icon will switch to a steady display. Charge your goLITE BLU for at least 8 hours before initial use. Subsequent charges should be complete in three to four hours. A single charge should last for three to five treatment sessions.

WARNING: Do not incinerate, disassemble, or expose to high temperatures (above 60^ C/ 140^ F). Internal batteries may overheat causing fire, or bursting. Use the specified AC/DC adapter only.

Positioning Your goLITE BLU

Use the goLITE BLU at a slight angle to your face (see figure 1). It is not necessary to look directly into the light.

• For best results, place the goLITE BLU approximately 20–30 inches from your eyes. Allow the light to bathe your face from the side.
• You can read, eat, work at the computer, watch TV, put on makeup, or exercise while using your goLITE BLU.
• Use your goLITE BLU in a well-lit room to minimize eyestrain.
• For best results, place the goLITE BLU near you at eye level so it shines directly into your eyes.
• The proper response to light therapy occurs through the retina of the eyes, not through the skin. However, you do not need to stare at the light. If you are in front of the goLITE BLU and position it close enough, only an occasional glance is needed achieve the maximum benefits.

When to Use Your goLITE BLU

Because an imbalance in circadian rhythm affects everybody differently, understanding how it affects you is critical to feeling better. Knowing what time to use the goLITE BLU can mean the difference between responding 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 for the best results.

Usage Duration and Intensity

Most people get beneficial results from fifteen to thirty minutes of usage each day. You can start using your goLITE BLU at 50% intensity and increase the level of light if you feel like your body is not responding within a week of beginning light therapy.

Time of Day

If you find it difficult getting up each day without an alarm clock or you are sleeping in, you need morning light. Use the goLITE BLU within the first hour or two after waking.

If you find it difficult staying awake in the late evening and wake up too early in the morning, you need evening light. Use the goLITE BLU before the onset of drowsiness.

If you don't notice a shifted circadian rhythm, use the goLITE BLU when you wake up in the morning for fifteen to thirty minutes and then again in the evening for approximately the same amount of time. Place the goLITE BLU further away from you during the evening treatment. This will keep your body clock from confusing the stronger morning signal with evening time. Don't use the goLITE BLU within two hours of bedtime. The goLITE BLU suppresses the nighttime hormones for at least two hours, and you may not be able to fall asleep.

Shift Work

Use the following techniques to adjust your circadian rhythm to your work shift.

Beginning a Night-shift Schedule

Many people benefit from receiving a 30-minute burst of light before work and then 15 minutes of light every three hours during work. This not only increases alertness and performance, but shifts the body clock as well. Within three days, your body clock will have changed to a night-shift schedule. Taking time-release melatonin upon arriving home after work may help accelerate the shifting of your body clock. After the second day, melatonin should not be necessary, and your body clock will have adapted to the new schedule.

Note: When coming off of night-shift work, it is important to wear sunglasses and avoid any bright light while going home. You should go to sleep as soon as possible after leaving work.

Returning to a Day-shift Schedule

On the day your night shift ends, continue to wear sunglasses and avoid bright light in the morning hours. Do not take melatonin in the morning. Use your goLITE BLU for 30 minutes at about midday. On the first day, you may take an afternoon nap if you are having trouble staying awake. Go to bed at your normal evening bedtime.

You may wish to use time-release melatonin in the early evening (about 7:00 p.m.) to accelerate your body clock to a normal schedule. You may want to wait a few hours after waking in the afternoon or evening before taking melatonin as it may cause drowsiness. This routine should only need to be repeated once or twice before you achieve a normal sleep/wake schedule.

After the first day, you should use the goLITE BLU each morning as needed for approximately 15–30 minutes.

For more detailed information about using your goLITE BLU to help adapt to shift work schedules, visit www.LightTherapy.com.

Jet Lag

Rapidly traveling across several time zones creates disharmony between your internal body clock and the new external time. This not only causes problems with sleeping, but influences mood and energy as well. Because specialized light is effective for shifting circadian rhythms, your goLITE BLU can quickly adjust your rhythm to the new time zone. The best strategy for combating jet lag is to shift your body clock a day or two before leaving.

Traveling East

Use your goLITE BLU in the morning two to three days before leaving. The number of time zones traveled corresponds to the hours needed to shift. On the first day, wake up an hour early and use the goLITE BLU for 30–45 minutes. This will shift your body clock up to three time zones. The next day(s) you need to awaken a couple of hours earlier and repeat this process. Taking time-released melatonin in the early evening or late afternoon can also help accelerate this shift. You should adjust your sleep schedule as described each day. Upon arrival, wear sunglasses to avoid any sunlight before 10:00 a.m. When returning, use your goLITE BLU in the evening for a few nights and avoid any morning light (see Traveling West).

Traveling West

Use your goLITE BLU in the evening for 30–40 minutes a few days before leaving, and use the goLITE BLU a couple of hours later each successive day. Each day you use the goLITE BLU, you shift your internal time up to three hours, and you can increase this shift up to six hours per day by taking melatonin in the morning. When returning, avoid any bright afternoon and evening light and be sure to use your goLITE BLU in the morning for a few days (see Traveling East).

Frequently Asked Questions

Do I have to take off my glasses when I use the goLITE BLU?

No. This specialized type of light is designed to work with or without glasses. However, you should not wear tinted glasses or sunglasses when using the goLITE.

Are there any major side effects?

The goLITE BLU is safe when used according to recommendations. There have been some reports of temporary headaches or nausea. This is usually resolved by sitting further away from the unit.

Can I get sunburn from using the goLITE BLU?

No. While typical fluorescent bulbs produce small amounts of UV light, BLUEWAVE Technology eliminates all UV light.

I've heard that light can be dangerous. Can the goLITE BLU damage my eyes?

The goLITE BLU emits safe levels of blue light, according to current standards. In fact, your goLITE BLU emits less blue light than other traditional forms of bright light therapy like full-spectrum, 10,000 lux white fluorescent light. However, if you suffer from an eye disease or have a history of eye disease in your family, you should consult your ophthalmologist before using your goLITE BLU. Also, if you are experiencing any temporary eye problems, wait until the problems are resolved before using the goLITE BLU.

When used as directed, all of our light products are free from ultraviolet light risk to the eye and produce a safe, diffused field of light. Our lights have been tested for ocular safety and have been used in dozens of government and clinical studies.

As with any bright light source, you should not stare directly into the light. The beneficial reaction happens when the melanopsin photoreceptors in the eye are stimulated. Since these photoreceptors lie in the peri phery of the eye, you will get a much better outcome if you position the goLITE BLU at a slight angle to your face.

Should I use the goLITE BLU every day?

You should use the goLITE BLU daily, especially during the winter months. Many people find that they don't need the light during the summer. Others use it year-round because they spend most of their time indoors and don't typically get the right kind of light signals to regulate circadian rhythms properly.

Can the light cause harm to children or pets?

No. The lights are safe around children and pets. The lights will actually draw many pets to sit by it.

Can I use the goLITE BLU more than once a day?

For most people, it is sufficient to use the goLITE BLU once a day. Keep in mind that using the goLITE BLU too late in the evening may adversely affect your sleep.

How long do the LEDs last?

Under normal usage, the LEDs are rated for 10,000 hours of use, which at 30 minutes per day all year round equals over 50 years of life.

What if one or more LEDs stop working prematurely?

In the unlikely event that one or two LEDs fail prematurely, the effectiveness of your goLITE BLU will not be diminished. You can continue to use your goLITE BLU normally. However, if several LEDs stop functioning, you should probably have your goLITE BLU repaired to ensure that you are receiving the correct treatment dosage. For more information, refer to your goLITE BLU warranty card.

What is DEMO on the display screen?

This is the Demonstration mode that is used to display the goLITE BLU at point-of-sale locations. If your goLITE BLU happens to be in this mode, DEMO will appear on your display screen. You will not need to be in this mode. While the goLITE BLU is off, press and hold the ON/OFF button for 10 seconds. The goLITE BLU will turn on and the word DEMO will clear from your display screen.

How do I use the reset button?

The goLITE has a reset button located in the stand storage cavity on the back of the unit. If the goLITE locks up or is not working correctly, you can reset the device by inserting the end of a paper clip into the reset button hole. The goLITE will reset and the memory contents will be cleared.
