Holiday feeling and better health throughout the year

People spend most of their lives indoors, shielded from natural daylight. The light that penetrates in buildings through the windows is too weak to have a positive influence on your biological clock. The electric light indoors is good enough for visual tasks but usually insufficient to compensate for the lack of daylight.

To optimize your light, you need to understand the four elements by which light influences our body: circadian rhythm, biological clock, daylight-detector, and the twilight zone.

People need to start recognizing the symptoms of being shielded from daylight: poor sleep quality, little energy during daytime and mood swings and relate these symptoms to the lack of light. Then, you can start acting. Examples illustrate how this works for sleep, Alzheimer patients, summertime, winter blues. A three-step approach is explained to bring good light into your life.
