Intended use
The Philips goLITE BLU is intended to make people feel more energetic,
to increase alertness, and to provide mood relief from the winter blues. If
you suffer from severe mood swings or depression, make sure to consult
a professional, and do not use this device for self-treatment. This product
has not been approved by FDA for treatment of seasonal affective
disorder (SAD).
Light - a natural energizer
Today’s busy modern lifestyles demand peak performance all day long.
Even the fittest person suffers energy dips, particularly when deprived of
natural daylight, such as in an office in winter. Daylight is essential to
well-being, keeping fit, and feeling energized throughout the day – just like
healthy nutrition and regular exercise. Philips goLITE BLU mimics the
natural energizing power of daylight on a bright sunny day. It stimulates
special receptors in the eye to trigger the body’s natural response to
sunlight. This helps you to fight energy dips, to feel more energetic, active
and alert, and to improve your mood.
Sleep patterns
The human body uses light cues, such as those provided by the sun, to
time certain internal functions. Properly timed rhythms regulate energy,
mood, sleep, appetite and digestion. Nature’s cues no longer govern our
modern lifestyle. Our day no longer starts at sunrise and ends at sunset,
and working days are getting longer. Moreover, our activities often extend
well into the night. Many people tend to get too little sleep during the
week, which diminishes their energy levels during the day. Using goLITE
BLU at the right time of day can help you establish and reinforce regular
sleep patterns.
Light via eyes
Research shows that a special photoreceptor in our eyes is responsible
for regulating our energy, mood and sleep/wake cycles. This receptor
responds mostly to the blue light of the summer sky. We do not get much
of this light in autumn and winter. Most indoor light does not provide
enough of this essential color. This appliance helps you to be at your best
by delivering the wavelength, color and intensity of light to which our
body responds most efficiently.

Winter blues
Lack of light during the darker winter months causes many people to
experience a noticeable drop in energy level and low spirits as fall sets in.
These symptoms, known as ‘winter blues’, may cause you to feel low,
listless and fatigued for weeks or even months. This affects both personal
performance and mood. Blue light therapy is a successful method to fight
these winter blues symptoms. It provides your body with summer vitality
throughout the dark winter months.

Using the goLITE BLU
When to use
Knowing at what time to use the goLITE BLU is essential. It may mean the
difference between feeling better in a few days instead of weeks and
between experiencing benefits or experiencing none. Follow these
guidelines to understand how light affects us and when to use the goLITE
BLU for the best results.
Most people experience benefits if they use the appliance 20 to 30
minutes each day. It is safe to use the goLITE BLU longer, provided you do
so at the correct time of day. You may notice some energizing effects of
light immediately. Other effects become noticeable after several days of
regular use.
Indoor life and energy dips
If you spend a lot of time indoors with little daylight and artificial light, you
can experience the energizing effects of the Philips goLITE BLU very
quickly after you switch it on.
Many people experience a natural dip in the afternoon. The goLITE BLU
can help you counteract this dip.
Winter blues
If you experience lower energy levels, an increased need for sleep, and a
lower mood in the dark season compared to spring and summer, use the
goLITE BLU for 20-30 minutes a day. Preferably use it in the morning to
help you start the day. You may also use it later during the day, but do not
use it in the last few hours before bedtime. If you do, the light could delay
your sleep and make you even less energetic the next day.
Sleep patterns
-- Morning persons tend to wake up early in the morning and usually
find it difficult to stay awake in the evening. If you want to get more
out of your evening, avoid bright light directly after waking up and use
the goLITE BLU in the evening.
-- Evening persons find it difficult to get up in the morning and are full
of energy in the evening. If this applies to you, you need morning light.
Use the goLITE BLU within the first 1 to 2 hours after you get out of
bed. Avoid bright light or blue-rich light in the last 4 hours before
bedtime. Daily use of the goLITE BLU in the morning may help you
establish a regular sleep pattern that allows you to function better in
the morning.
Note: If your desired wake-up time is less than six hours after your normal
bedtime, do not use the goLITE BLU immediately after you wake up.This
could give your body a signal that is opposite to the one intended.

Light intensity
Use the goLITE BLU in addition to the normal room lighting. The goLITE
BLU is more comfortable to use in a well-lit room. Adjust the brightness
to a comfortable level. Allow a few minutes for your eyes to get used to
the bright light. If the highest setting is too bright for you, start using the
goLITE BLU at a lower setting. Increase the light intensity if you feel no
effect after a week.
