- 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

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,

can be determined as described above, but should be aligned with your
therapist.

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
