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,

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).

10 English

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.

English

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 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.
