Health light in the psychiatry

The effects of artificial lighting on symptoms of eating disorder – a pilot study

What was the purpose of the project?

The objective of this pilot study is to explore if and how artificial lighting affects symptoms of eating disorders (ED). If an influence of artificial lighting on symptoms of eating disorders is indicated, the study will provide information on how to improve light exposure to ED patients in psychiatric treatment units.

In addition, the outcomes may help identify a better system for measurement and adjustment of the specific light variables of colour temperature and light intensity.

Chosen solution

All lighting in wards, common rooms (eating and recreation rooms) are equipped with programmable Circadian Rhythm Lighting (CRL), with manual override to enable normal on/off lighting.

Hypothesis 1: Artificial lighting adjusted to circadian rhythms will improve well-being in patients with eating disorders
Hypothesis 2: Exposure to high CCT/high LUX intensity will reduce affective symptoms in patients with eating disorders.

The study will use lighting variables of both colour temperature as well as light intensity.
