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.
