When choosing a house, we all want light, lots of light. Somehow, we sense that the sun is going to do us good.
But what happens in our bodies if we spend a lot of time in places without sunlight? What is the best artificial light for working? What are the effects of not using the right bulb?
If your eyes get tired and you return from work with migraines, you may need to learn what circadian lighting can do for you.
Your body moves to the rhythm of light
Human beings are creatures of habit. Seemingly small changes in the outside world can trigger all kinds of changes inside our body. A good example are the two time changes we make every year (which will disappear). Something seemingly as trivial as moving the clocks forward or back by an hour causes sleep problems in a significant percentage of the population every year.
Most of us have accustomed our body to be active during the day and to sleep at night. As a result, our cells use sunlight to orientate themselves and accelerate or slow down their metabolism. Circadian Rhythms are the set of mental, physical and behavioural changes that we experience during 24 hours.
In contemporary Western civilisation, humans spend most of their lives indoors, under a roof, with artificial light. How does this affect our circadian rhythms?
It is logical to think that our metabolism can be affected if we barely see sunlight. In recent decades, scientists have been engaged in investigating circadian lighting, which consists of simulating the biological rhythms of the human body. Their findings include the relationship between altered circadian rhythms and the development of eating disorders, insomnia and depression.
