The Philips Wake-up Light helps you wake up more pleasantly. The light intensity of the lamp
gradually increases to the set level in the 30 minutes before the set wake-up time. The light gently
prepares your body for waking up at the set time. To make waking up an even more pleasant
experience, you can use natural wake-up sounds or the FM radio (HF3470 only).
the effects of the Wake-up light
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 prepare our body for
waking up and getting alert. People who use the Wake-up Light wake up more easily, have a better
overall mood in the morning and feel more energetic. Because the sensitivity to light differs per
person, you can set the light intensity of your Wake-up Light to a level that matches your light
sensitivity for an optimal start of the day.
