During the day, the rotation of the earth, in combination with our climate, will result in various lighting conditions, both regarding colour and intensity. The human body is affected by this day-night rhythm. Studies have shown that the production of hormones, such as melatonin and cortisol, are affected by this rhythm.
Cortisol gives us an active and alert feeling, while the hormone melatonin makes us feel sleepy and relaxed. Maintaining a good balance between these will ensure optimum performance during the day, followed by a good night’s sleep.
Despite the fact that most people today dwell indoors, it is essential to our well-being to receive sufficient amounts of daylight. In places where daylight can hardly penetrate although people need to be there, so-called bio-dynamic lighting may prove the ideal solution. Bio-dynamic lighting is able to automatically mimic the variation in colour and intensity of natural daylight. Deerns will help you make the right choices when you decide to choose for these lighting systems. The areas of application regarding bio-dynamic systems particularly include those where people work in shifts, such as hospitals, emergency centres, etc. Bio-dynamic lighting may also be used in geriatric and psycho-geriatric care centres, where people often have to deal with disrupted day-night rhythms.
