CIRCADIAN LIGHTING

Balance between light and dark

WHY IS LIGHT IMPORTANT?

The human system is designed to derive energy from a balance between light and darkness, with daylight playing a pivotal role. Any disruption in this balance can have a negative impact on our well-being. A prime example is the discomfort many experience when dealing with jet lag. Concentration wanes, focus is lost, and one feels disoriented and fatigued, unable to sleep. This is a result of our body's natural rhythm being thrown off, leading to decreased efficiency and lack of alertness. The same holds true for individuals subjected to night shifts or those who work in darkness throughout the entire workday.

Humans thrive best with a stable circadian rhythm, with daylight during the day and darkness at night. This is crucial in order to ensure the undisturbed functioning of the vital hormone melatonin. Melatonin, an antioxidant, is promoted in darkness and inhibited by daylight.

Today, we spend approximately 90% of our time indoors, which means that the built environment plays a crucial role in the light we are exposed to. However, we rarely consider the impact that light has on our sleep, circadian rhythm, and overall health. For vulnerable patients, maintaining a normal circadian rhythm is particularly important to ensure the best treatment and care outcomes. At the same time, night shift workers are affected by a disrupted circadian rhythm.

WHO BENEFITS FROM CIRCADIAN LIGHTING?

Everyone needs a good and stable circadian rhythm to thrive and support their health. Circadian lighting are beneficial for anyone who spends the majority of their day indoors, especially those who experience imbalances in their sleep-wake cycle or need to regulate their circadian rhythm. The healthcare sector has a particular need for these lights. Here are some of the groups who will particularly benefit from circadian lighting:

Psychiatric patients Inpatients in psychiatry

Circadian lighting is effectively used in the treatment of psychiatric patients who struggle with settling down in the evening and achieving a restful and steady sleep. Additionally, the light can be tailored to meet individual patient's needs for stimulation as part of their treatment.

Somatic patients Intensive Care & RehabilitationPatients receiving somatic treatment in intensive care or rehabilitation often spend their entire time indoors, making it difficult for them to maintain a stable circadian rhythm. We know that this rhythm plays a crucial role in the effectiveness of treatment and the duration of the illness.

Senior citizens Nursing home residentsElderly citizens, especially those with conditions like dementia, spend over 90% of their time indoors. Consequently, they lack exposure to natural sunlight, which affects their circadian rhythm. Additionally, lighting that mimics the natural day-night cycle helps promote relaxation and a restful night's sleep.

Vulnerable citizens Treatment & CareVulnerable individuals require stability in their daily lives, and the circadian rhythm plays a crucial role in creating a good day and night for them. With circadian lighting, they can gain the necessary energy during the day and unwind and relax towards the evening. Vulnerable individuals need lighting that caters to their specific needs, ensuring a stable circadian rhythm for them.
