Introduction

Read this user manual carefully before using this Philips
energy light.
Intended use
Philips 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 energiser
Today’s busy modern lifestyles demand peak performance all day long.
Even the ttest person suffers energy dips, particularly when deprived
of natural daylight, such as in an ofce in winter. Daylight is essential to
well-being, keeping t and feeling energised throughout the day – just like
healthy nutrition and regular exercise. Philips EnergyUp Intense Blue
mimics the natural energising 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 ght 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, 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.
ENGLISH

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
colour. This appliance helps you to be at your best by delivering the wavelength,
colour and intensity of light to which our body responds most efciently.
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 ght 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, icker)
is observed, additional measures may be necessary, such as re-orientation of
the radio frequency communication equipment or the EnergyUp.
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 EnergyUp
When to use the EnergyUp
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 benets 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 benets 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
energising 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 articial light,
you can experience the energising effects of the Philips EnergyUp very
quickly after you switch it on. You can also use the appliance as an extra
source of light throughout the day (but not in the evening or at night)
to compensate for the lack of natural daylight.
Many people experience a natural dip in the afternoon. The Philips
EnergyUp can help you counteract this dip.
ENGLISH10

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.
Sleep patterns
- Morning persons usually wake up early in the morning and usually
nd it difcult 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 close to bedtime.
- Evening persons nd it difcult 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 rst 1-2 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 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 travelling 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 inuences 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.
Travelling 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
ENGLISH12

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 ight, 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 ight,
avoid any bright light in the morning.
Travelling 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
additional three 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.
When you arrive at your destination, try to stay awake until bedtime and
avoid bright evening light (wear sunglasses) for the rst 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.
