Read this user manual carefully before using this Philips appliance.
Intended use
This Philips appliance EnergyUp Intense Blue is intended to make
people feel more energetic, to adjust circadian rhythms and to
provide relief from the winter blues. Medical intended use of this
appliance is to treat winter depression or SAD (seasonal affective
disorder). Treatment of SAD must always take place under medical
supervision.
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
EnergyUp Intense Blue 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.
Circadian rhythms and 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. These daily internal
cycles, called circadian rhythms, sometimes fall out of sync with
nature, which can have impact on our well-being. Nature’s cues no
longer govern our modern lifestyle. Our day no longer starts at sunrise
and ends at sunset, working days are getting longer, and many
people work in shifts. Moreover, our activities often extend well into
the night. Many people tend to get too little sleep during the week,
6English

which diminishes their energy levels during the day. Using Philips
EnergyUp Intense Blue 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, colour 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
autumn 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.

Electromagnetic compatibility (EMC)
Portable and mobile radio frequency communication equipment,
such as mobile phones, cordless telephones and their base stations,
walkie-talkies, and wireless home network devices (routers), can
affect the Philips EnergyUp. They must therefore not be used in close
proximity to the EnergyUp. If this cannot be avoided, the EnergyUp
must be observed to verify normal operation. If abnormal
performance (e.g. loss of functionality, light inconsistency, flicker) is
observed, additional measures may be necessary, such as re-
orientation of the radio frequency communication equipment or the
EnergyUp (see section 'EMC information' in chapter 'Specifications'
for more details).
General
The adapter is equipped with an automatic voltage selector and is
suitable for mains voltages ranging from 100 to 240 Vac, 50/60 Hz.

Using the appliance
When to use
Knowing at what time to use the Philips EnergyUp 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 Philips EnergyUp for the best results.
Duration
Most people experience benefits if they use the appliance 20 to 30
minutes each day. It is safe to use the Philips EnergyUp 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 EnergyUp
very quickly after you switch it on.
Many people experience a natural dip in the afternoon. The Philips
EnergyUp 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 energy light 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.
Winter depression
If your seasonal mood swings are more severe and you suffer from
depression, consult a therapist and only use light therapy under
supervision. Your therapist may prescribe 30 minutes of treatment per
day at level 1 or 2 over several weeks.

English

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 Philips EnergyUp 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 Philips EnergyUp within the first 1-2 hours
after you get out of bed. Avoid bright light in the last 4 hours
before bedtime. Daily use of the Philips EnergyUp 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 Philips EnergyUp immediately after
you wake up. This could give your body a signal that is opposite to
the one intended.

Jet lag
Rapidly traveling across several time zones puts your internal body
clock out of sync with the new external time. This not only causes
sleeping problems, but also influences your mood and energy level. If
you stay for more than a few days in the other time zone, you may
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. One
of the best strategies to deal with jet lag is to start shifting your body
clock and sleep times several days before you leave.
Traveling east
When you travel east, you have to advance your sleep time by a
number of hours that equals the time zones you cross. You can shift
your body clock forwards in steps of one hour a day. The number of
time zones you cross determines how many days before departure
you have to start using the Philips EnergyUp. Use the appliance for 30
minutes after you wake up. Avoid bright light in the evening and go to
bed early. When you arrive at your destination, avoid bright light
during your normal sleep period. Expose yourself to bright light at the
end of this period to advance your body clock further to the local
time.
Before your return flight, use the Philips EnergyUp late in the evening
for a couple of days. On the last night of the trip, try to stay up and
use the appliance as late as possible after midnight. On the day of the
flight, avoid any bright light in the morning.
Traveling west
Since most people’s body clocks adjust more easily to later time
zones, you only have to use the Philips EnergyUp for one day before
you travel across four time zones. Add an additional preparation day
for each three additional time zones. You do not have to use the
Philips EnergyUp for more than three days, even on longer
westbound trips. Use the appliance for 30–40 minutes late in the
evening. Start two or three days before you leave. Use the appliance
two hours later the following nights.
13
English

When you arrive at your destination, try to stay awake until bedtime
and avoid bright evening light (wear sunglasses) for the first few days.
Before you travel home, avoid any bright afternoon and evening light.
Use the Philips EnergyUp in the morning for a few days.
Light intensity
Use the Philips EnergyUp in addition to the normal room lighting. The
Philips EnergyUp 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 appliance at a lower setting. Increase the light
intensity if you feel no effect after a week.
