Notice PHILIPS HF3461

« The light in the morning stimulates the secretion of the hormone cortisol, which makes us awake and alert. Optimally, the circadian rhythms are in sync with our sleep-wake rhythm. Disturbed sleep and circadian rhythms can severely impact our health, performance and productivity. In autumn and winter, when the days are shorter and darker, many people experience tiredness and need more sleep. Lack of energy and trouble to get up in the morning are common symptoms of the winter blues. Other symptoms may be unexpected mood changes, concentration problems and a craving for food rich in fattening carbohydrates. Some people may even develop a serious depression (seasonal affective disorder or SAD), which disappears when spring comes. The effects of dawn simulation The Philips Wake-up Light gently prepares your body for waking up during the last half hour of sleep. In the early morning hours our eyes are more sensitive to light than when we are awake. During that period the relatively low light levels of a simulated natural sunrise elevate the cortisol level shortly after awakening. Clinical studies have shown that regular use of a dawn simulator can alleviate even the severest symptoms of the winter blues, improving productivity and concentration. In addition, people who use the Wake-up Light wake up more easily, have a better overall mood in the morning and feel more energetic. With the Philips Wake-up Light, you can set the light level that corresponds to your light sensitivity for optimum dawn simulation.
