Daylight

is enlightenment

Health

Whether you’re a night owl, a caveman or a pessimist, we are all children of light, at the end of the day – whether we want to be or not.


It is hardly a secret that man cannot live without daylight. Of course some people can imagine spending a whole week in a dark living room, watching their favourite TV series. The reality would probably look quite different after just a few days of this. Our bodies instinctively seek light, and there is a good, life-sustaining reason for this.

Productivity

Work is not always “a place in the sun” – but it should be, boss!


The artificial lighting of workplaces is one of the major causes of “sick building syndrome” (SBS); however, illumination via daylight positively affects the health even if disruption occurs. People who work or live in unfavourable lighting conditions feel tired sooner, get more headaches and/or suffer more frequently from a lack of concentration. The further away from the window a workstation is, the worse these problems are, and thus the lower the level of productive performance.

Well-Being

Maybe that last lecture was not as boring as it might have seemed at first glance? We also listen with our eyes!


Anyone who has nodded off in a dark lecture hall or meeting room at 9.30 in the morning knows how easy it is for a lack of light to put our bodies into sleep mode. And it is not always dependent on the given presentations or topics. It makes a huge difference whether you're in a bright room bathed in light, or in a type of suspended darkness. And this has no minor impact on our hormones.

Staple foods

There is hardly any other factor which affects life on our planet as much as the light from the sun – so let’s get some!


It is not only plants that feed on light, but also humans. And this is not merely meant as a metaphor to describe human happiness and hope, but a fact that we can see, feel and even taste. This is because without sufficient sunlight, the vintage and many other harvested foods are pretty poor. So you might say that daylight is not only the basis for all our staple foods, but that it even influences our eating habits.

Enlightening occupations

Crystal-clear jobs with vision and light on the horizon, especially for those who like to sit in glass houses.


If you enter the term “occupations” in a search engine, you get a diverse range of jobs,  whose number increases almost on a daily basis. You’ll also come across a number of professions which deal with perhaps the most fascinating material in the world: glass. What do you call someone who produces this material, and what actually is glass?

Happiness

Happiness is sometimes a feeling, sometimes a thought, sometimes a desire – but it is always light.


Many treatises have been written in the course of human history, searching for an answer to the question of what “happiness” really means. How it feels for each individual and what it constitutes is perhaps one of life's great mysteries. It is however certain that light makes you happy. Without light, there would be no life.

Serotonin

Daylight is a decisive factor in ensuring that our body chemistry is right.


The idea that daylight is healthy appears in every third sentence on this page. But what’s the deal with this serotonin and what is it anyway? Where and how is it important and useful for the human body? The explanations – which we may have failed to take note of in our biology lessons at school – are in fact very interesting:

Biological clock

Man is a living clock mechanism, and so that we tick correctly, we need healthy light. Why on earth...?


How often have you heard yourself or other people say things such as: “First we need to find our rhythm”, or “we need to get back in the swing of things.” Are these empty words and excuses, or is there perhaps something more fundamental behind it? What does it actually mean for the human body to be out of kilter, and why does daylight play such a large part in this?

Vitamin D

You know your ABC, but what about Vitamin D? Why do we need it, and why are ever more people taking additional amounts of it?


In addition to the production of melatonin and the related circadian rhythm, natural light also affects our stores of Vitamin D. Vitamin D helps the body to absorb calcium from the diet, and is therefore important for bone formation and bone stability. The age-related disease osteoporosis, which leads to brittle bones, may be worse where there is a lack of Vitamin D.

Spectrum of light

The whole range of colours, with all hues – from beautiful to harsh.


Even though our world sometimes seems to consist solely of black and white, they are in fact always around us: colours. In order to view them, we don’t just need optimism, but above all light. This is because there is a reason for the fact that we cannot differentiate between colours or see them in the dark.

Worthy professions: Lighting designer

An overview of lighting design

Nowadays, lighting design is not only about playing with light and using it artistically, but increasingly has the aim of improving health and providing conscious illumination. As a renowned lighting designer, Prof. Peter Andres not only knows why we do so, but how.

Light, from a health professional's point of view

Anyone who sees is working hard.

Physiological studies showed that 25 percent of our energy resources are consumed through sight. Correct lighting therefore plays an important role.

Sick building syndrome

Feeling unwell at work or school

...is not always due to your boss or your maths lesson. Sometimes, a building can also make you ill.

Smart lighting technology

...in the office.

The incidence of light from outside can also be influenced by the use of “intelligent glass”. Electrochromic glass...

Biological lighting design

Nowadays, it’s not just about illuminating rooms

...it’s also about living with the right light.
