Philips EnergyUp Intense Blue is intended to make people feel more

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 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 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 Intense Blue at the right time of day can
help you establish and reinforce regular sleep patterns.
