Lux

The Nordic summer has unique qualities that are difficult to explain. After long, dark winters, the world opens up and the light embraces you. You are giddy. The light is the defining factor. Light illumination is measured in units called Lux.

On a moonless, overcast night you get about 0.0001 lux. The lighting in an average family living room is about 50 lux. The Nordic winter - overcast, snow, rain and with a sunset, in Copenhagen anyway, at around 15:30 in mid-December - is not generous in it's distribution of lux. Rarely does it rise above about 400 lux.

On a sunny, summer's day, on the other hand, your body and mind is splashed with upwards of 100,000 lux. What a shock in the first sunny days of spring. It triggers that feeling of a rush and it increases your energy levels and even your sexual desire. It's quite a difference between winter and summer. I love the Copenhagen summer, needless to say.
