The lighting project Glamox has completed at St Olav’s Hospital in Trondheim, Østmarka, was planned based on this type of research, with a strong emphasis on the use of light for treatment purposes. This project called for HCL lighting that mimics natural sunlight during the day, energising the patients. It then switches to orange light from 6 p.m. onwards, causing their bodies to release more melatonin. This has a calming effect and makes the patients’ hyperactive phases milder and allows them to improve their sleep rhythm.
Most patient room lighting should be recessed and sturdy enough to prevent damage. This type of lighting is called anti-ligature lighting and is meant to ward off patients from hurting themselves – either by hanging up materials off lamps with protruding elements, or by damaging pieces of lighting and other equipment to create sharp objects that can be used for self-harm. An adequately high IK mechanical impact resistance class is important, in addition to robust products with firm hanging points, curved edges and tamper-proof entry fixings.
