BIODYNAMIC LIGHTING | LUM CONNECT VTL

The Right Light Throughout the Day

 

Our bodies work through the same cycle every day. Our internal clock determines sleeping and waking phases, as well as heartbeats, blood pressure and mood – a rhythm of biological processes controlled and supported by light, as well as hormones, specifically cortisol and melatonin. A lack of light throughout the course of the day can result in chronic fatigue, sleep disorders or depression. 

VTL (Visual Timing Light) “controls” smart lighting in the office by working in tandem with the body's natural endorphins. This innovative light management system brings the dynamics of natural daylight into the building to extend the emotional and ergonomic benefits of light quality. Biodynamic light (Human Centric Lighting) can provide lasting well-being for employees in offices with insufficient daylight and also during the winter months when there are much fewer sunny days.

Light in the interaction with hormones

Cortisol and melatonin levels of the body during a typical course of the day.

Morning 



The hormone cortisol is produced in the body in the morning. It stimulates the metabolism and programs the body for day mode. The first morning light suppresses the production of the sleep hormone melatonin. VTL supports the activity of the stress hormone cortisol at the beginning of office work by stimulating cold-tone light and high illuminance values.


Noon



The levels of cortisol decrease over the course of the day. However, good performance levels of the office workers are still maintained around midday. For VTL, this means that it continues providing mainly activating cold-tone light and high illuminance values.

Afternoon



In the afternoon, the production of cortisol in the body has already decreased significantly, with the active working phase approaching its end. The production of the sleep hormone is not yet required at this moment. VTL supports this transitional period by means of a neutral mixed light. The illuminance is gradually reduced.

Evening 



The melatonin hormone makes workers tired and reduces the activity in favor of night sleep. With biodynamic light during the day, the melatonin level is correspondingly high during the night. The person sleeps well and is rested and productive the next day.  VTL supports the transition to the rest phase through reduced brightness and relaxing warm tone light.
