light and health
The human body uses light cues, such as those provided by the sun, to
time certain functions. Light exposure can boost mood and energy.
Light has direct alerting and energizing effects and can improve 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 the fall 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.
The blue light of the summer sky is well known. We do not get as much
of this light in the fall and winter, and indoor light does not emit enough
of this essential color. The goLITE BLU energy light helps to deliver the
wavelength, color and intensity of light that we see in summer.

Preparing for use
It is very important that you know how long and how often you should
use your Philips goLITE BLU energy light. This knowledge can mean the
difference between successfully responding to light and not responding at
all. Visit www.lighttherapy.com for a free assessment and to customize a
light therapy schedule just for you.
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 can boost mood and energy and when to use the goLITE BLU for
the best results.
Duration and intensity
Most people get beneficial results from 15 to 45 minutes of usage each
day. You can start using the goLITE BLU at medium intensity and increase
the light intensity if you feel no response after a week.
Timing
Using the goLITE BLU energy light at any time of day directly affects your
alertness. You can use the goLITE BLU energy light as a light bath for the
winter blues throughout the day. The best time to use it is in the morning.
Do not use the goLITE BLU 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
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
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 is not as important. You can use the goLITE BLU in the
morning or around midday. For example, when you wake up in the
morning, use it for 15 to 30 minutes and then again at midday or in
the evening for approximately the same amount of time. Place the
goLITE BLU further away from you during the evening session. Do
not use the goLITE BLU within two hours of your desired bedtime or
you may not be able to fall asleep.
