Insomnia, a series about the light pollution problem in Hong Kong and its effects on its inhabitants. Stars in the night sky above Hong Kong Island are searched in vain. The city is enveloped in a pink-orange haze that downright suppresses the darkness of the night. Hong Kongs urban night sky is 100 to 1000 times brighter than the international brightness standard between 8.30 and 11:00pm. Light pollution has an impact on Hong Kong residents, especially on their sleep quality and well-being. Artificial light in the evening hours influences our internal clock, which in turn regulates processes such as hormone production. A disturbance of the day-night rhythm is associated with various physiological and psychological disorders, including depression, insomnia and cardiovascular diseases.
