The sun shines outside a Copenhagen care home, but residents inside won’t feel its warm glow on their skin.
The lack of exposure to daylight disrupted the body clocks of the people there leaving them struggling to sleep.
When outside, daylight enters the eyes and hits the brain, sending signals to the pineal gland to release melatonin, which makes us feel sleepy.
Scientists created special lighting to replicate normal daylight and installed it at the care home. The results are groundbreaking.
Care home worker Jim Hempel says the residents are now sleeping soundly throughout the night. It took “four or five months” for the lighting to slowly reset the brains of the elderly so their internal body clocks returned to normal.
The lighting was created by Danish company Chromaviso. Using knowledge of the colors of natural light, combined with insights from clinicians, they’ve created a lumiere mimicking the fluctuating changes in light over a 24-hour period.
