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 increases
the production of energy hormones and prepares your body for waking up in a very natural way. It
also makes you feel more energetic. To make waking up an even more pleasant experience, you can
use natural wake-up sounds or the FM radio. The appliance can also be used as a reading lamp.

light and the biological clock

Exposure to light regulates the biological clock that controls the body's sleep-wake rhythm. The level
of the hormone melatonin rises in the evening, preparing our body for sleep. The light in the
morning stimulates the production of the hormone cortisol, which makes us awake and alert.
Optimally, the sleep-wake rhythm is in sync with the rhythm of our daily life. This is often not the
case in modern life, as we often have to wake up when it is still dark.
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 elevate the cortisol
level shortly after awakening. People who use the Wake-up Light wake up more easily, have a better
overall mood in the morning and feel more energetic. Starting the day with the Wake-Up Light may
have a positive effect on your productivity and concentration. 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.
