Psychiatry and circadian rhythms

Ugeskr Læger 2018;180:V04180278

Circadian and seasonal rhythm disturbances are prominent in patients with psychiatric disorders.

Correctly administered, light can be used as an effective treatment for seasonal and non-seasonal depression and for stabilising the sleep-wake cycle. Blocking blue light in the evening may provide a non-pharmacological anti-manic tool. Current developments use dynamic lighting built into somatic and psychiatric hospitals to maximise the beneficial effects of light.
