Lighting for Hospitals

Adaptive Lighting for Hospitals Shifts

Hospitals run 24 hours a day, seven days a week. Nurses, residents and specialists in Emergency departments and ICUs bear the brunt of  working nights in artificial light. They have prolonged, regular high exposure to blue light when our natural circadian rhythm would expect us to be asleep.

At the end of each shift there is handover. Tiredness from the night shift finishing may cause incorrect or missing information during the handover. Night staff then have the difficulty falling asleep during the day. Tiredness and sleep deprivation compounds over time exacerbating these issues.

With circadian lighting these issues can be reduced. Natural daylight rhythms can be mimicked on the night shift. As the nightshift comes to an end red light can be increased, helping staff to stay alert for handover and the drive home, but not causing interruption to melatonin and sleep hormone. The night shift lighting mimics daylight signalling to the staff that when their shift ends it is time to go home and go to sleep.
