New Philips lighting solution increases duration of sleep for hospital patients
Bericht
Research carried out at Maastricht University Medical Center+ in partnership with Philips
Eindhoven / Maastricht – The Maastricht University Medical Center+ (Maastricht UMC+) has carried out research in partnership with Philips to investigate the effect of light on the sleep-wake rhythm of cardiac patients. The research shows that after seven days in a patient room fitted with HealWell - a new lighting system developed by Philips which mimics the natural day/night cycle outdoors - patients sleep on average 8% longer. After one week in a patient room fitted with standard lighting, on the other hand, patients' sleep duration was in fact slightly shorter than on the first night.
Sleep essential part of recovery process
Existing scientific research has shown that high levels of light during the day help to regulate the human biological clock and the sleep-wake rhythm. If a person's biorhythm is less than optimum, this can disrupt sleep and give rise to all manner of health problems. Philips HealWell combines the positive biological effects of natural daylight with a pleasant atmosphere in the patient room. This has a positive effect on the patient's sleep patterns and that in turn has a positive effect on their biorhythm, which is important for their health and well-being. HealWell also enables patients to create a pleasant atmosphere from the comfort of their hospital bed and enables caregivers to create optimum light in which to work.
Improvements
The research has demonstrated some significant improvements: the time it takes a patient to fall asleep is reduced by approximately 30% during the period between the first and the seventh night and at the same time the duration of sleep at night increases by on average 8%. This means that a patient sleeps on average 30 minutes longer.The research also shows that patients really appreciate being able to select the ambient lighting themselves.
