Summary

The aim of this project is to evaluate the effect of a dynamic light in order to improve the circadian rhythm, provide a better sleep and well-being, and in the long run an improved recovery. The primary question is whether dynamic artificial light with circadian stimulus can affect the circadian rhythm. The secondary question is whether this also provides better sleep and well-being.

The group that is particularly interesting to study is a geriatric population that is more sensitive to circadian rhythm disorders, sleep disorders and confusion in connection with hospitalization and that can be of particular benefit from this intervention.
