Intended use

This Philips appliance EnergyUp Natural White 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 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 energised throughout the day – just like healthy
nutrition and regular exercise. Philips EnergyUp Natural White 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 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, which diminishes their energy levels during the day. Using Philips EnergyUp Natural
White at the right time of day can help you establish and reinforce regular sleep patterns.
Light via eyes
Research shows that bright light via the eyes influences the regulation of our energy level, mood and
sleep/wake cycle. Indoor spaces generally do not provide enough light intensity. This appliance helps
you to be at your best by delivering high quality intense light whenever and wherever you need it.
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. Bright light therapy is a successful method to fight these winter blues
symptoms. It provides your body with summer vitality throughout the dark winter months.
