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

night. Many people tend to get too little sleep during the week, which diminishes their energy
levels during the day. Using Philips EnergyLight at the right time of day can help you establish
and reinforce regular sleep patterns.

these winter blues symptoms. It provides your body with summer vitality throughout the dark
