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.
