It has long been known that light does more than just help one sees and create ambience in rooms. But scientific studies also show that the right light also has a positive effect on our well-being, biorhythm and health. We are referring to the third biological dimension of light – the Human Centric Lighting.

Although our biological rhythm of 24 hours is genetically programmed, it must be re-synchronized daily through daylight or artificial light which is similar to daylight. The hormones cortisol, melatonin and serotonin are primarily at play here. If the body lacks light as a timer or clock, the result can be chronic fatigue, sleep disorders or depressions.

The right amount is key. For artificial light to be biologically effective, certain parameters must be observed which nature reveals to us. In rooms, a sky of artificial light is created through a combination of direct and indirect sources of light. They homogeneously light up the upper wall section and the ceiling.

An aging eye requires a much higher level of illuminance. Light enables the ability to move and the freedom to do what one wants as far as possible. Light that is shadow-free and low in glare has a positive impact on spatial perception.

Lack of orientation, insecurity and urge to move are typical for patients suffering from dementia. They are often in a state of semi-consciousness which is intensified even more due to insufficient light influences. Consequences of which are pathological restlessness, sleep problems through to complete reversal of day and night rhythm. A biodynamic lighting promotes biorhythm in a gentle and effective way.

Light in the morning invigorates the spirit and facilitates activity. From middle of the day onwards the warm light supports the body and prepares it for the night. The day and night rhythm or the biorhythm has a lasting stabilizing effect. Some gerontologists view it even as an opportunity to reduce administration of sleep-inducing drugs.

Staff members report that the light is good for the soul and strains the eyes less. If the residents can move without fear and are active during the day, it also simplifies the work for the personnel.

The higher investment costs pay off: thanks to the very high light output of biodynamic luminaires, fewer luminaires are needed in comparison to the conventional room luminaires. In addition, the light management system also helps in saving energy.
