Light for a healthy biorhythm | Gurgaon | Noida | Delhi NCR
Light is the basis for life and growth. For billions of people, the day regularly begins with the first rays of sunshine. Our natural day-night rhythm is closely related to the sun and its different light qualities. Many processes in the organism are adapted to this cycle. Human Centric Lighting carries d series into account by supporting by artificial lighting our natural needs for light and designed so that light optimally supports the processes in the body and enabled.
Once every six months, when the time is changed, each and every one of us can physically feel how the daylight rhythm affects our well-being. Our body often does not put up with the change simply because it depends on this circadian (diurnal, cyclical) rhythm. Hormone levels, blood pressure, mood and willingness to perform change according to the internal clock and thus influence our health and well-being.
Over the past 100 years, humans have created a global 24-hour society that runs counter to our natural day-night rhythm. In our modern civilization it doesn’t get dark any more in the evening. On the contrary: Artificially lit rooms shape our lives today to a great extent, whether during the day or at night. As we now know, this apparent independence from the time of day is not particularly healthy.
How does light act as a clock on the internal clock?
We have known since 2001 that light affects us humans even more than we thought before. At that time, scientists at Jefferson Medical College in Philadelphia discovered a new receptor in the eye that is not involved in the actual visual process. However, it reacts particularly to light wavelengths in the short-wave “blue” range of the light spectrum. A photo protein that works in the nerve cells of the eye responds to this. It’s called melanopsin and it largely controls our hormones.
A sensational discovery. Since then it has been clear that when light falls in the eye, that melanopsin ensures that our internal clock is clocked. The light pulse is therefore an essential factor for a healthy day-night rhythm and controls many unconscious body processes – from productivity and alertness to tiredness and healthy sleep.
We can clearly say: light has emotional and psychological effects on our body. Biologically healthy lighting should therefore always be based on natural daylight and specifically adapt to the course of the day.
Since the discovery of the new receptor in the eye, science and industry have been concerned with understanding the non-visual effects of light on people with the aim of technically simulating the effects of natural light. Light color and illuminate should adapt to the circadian rhythm throughout the day.
The composition and intensity of the light and color spectrum of different light sources have different effects on people. Conversely, this also means that the right lighting can increase well-being and positively influence our mood.
Human Centric Lighting describes a combination of non-visual and visual support for humans on a biological level. The light is designed and controlled in such a way that it optimally promotes and activates the processes in the body.
What does Human Centric Lighting look like in practice ?
Since light with high intensity and an increased blue component supports performance in the morning and noon, it should be adjustable indoors, for example via dimmers, light color control and light direction.
In the evening, individual spots with a warmer light color are more useful. The illuminate should now decrease while the red components increase. This supports the person in preparation for the sleep phase. Above all, the visual impression of pleasantly warm light then plays a role.
The work of the development departments has paid off. Applications of biologically effective light are already convincing. Various model tests have already been carried out successfully at workplaces or in schools.
Biologically effective lighting systems in the sense of Human Centric Lighting are always smart systems that control the light according to the time of day, personal needs and habits and adapt its spectrum to the time of day.
Humans have known electric light for almost 150 years. Now the age of biologically effective light has begun.
