Story summary

In Trondheim, Norway, researchers tested lighting design in psychiatric wards by comparing 476 patients in a blue-depleted circadian-adapted ward with those in standard lighting.
The circadian-adapted ward yielded greater clinical improvement and reduced aggression among patients.
Experts say the approach could enhance treatment quality and be applicable to care homes.
Future developments may include personalized light therapy based on individual circadian rhythms, potentially improving sleep and reducing anxiety without medication.
