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 ofce in winter. Daylight is essential to wellbeing, 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 star ts 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.

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 efciently.
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.
