Daylight and health

For all of our planetʼs history, there has been night and day, driving the rhythms of life across days and seasons… until the invention of the light bulb.

By disrupting the body clock, the lack of daylight can affect the quality of our sleep, our mood and our productivity. It can also lead to a lack of vitamin D and a weakened immune system, and cause or exacerbate certain diseases such as myopia, depression and diabetes. Fortunately, this also means that daylight can help prevent and even treat these disorders in many cases.

Daylight in traditional societies: lessons for today’s health crisis

Our initial impressions suggest there are several lessons that our society could learn from our neighbors in the Pacific while we face the COVID-19 crisis. One is the importance of shifting back to natural rhythms as ...

Little contact to people outside the family, less spontaneous decisions to visit a museum or a concert and less sports outside ...

The Pre-antibiotic Age – forgotten knowledge coming back in to light…

British pioneering scientists Downes and Blunt demonstrated how sunlight could kill and inhibit the development of the – at this time in 1877 – newly discovered bacteria. By placing bacteria in different environments, respectively in direct sunlight, indirect sunlight and darkness. Downes and Blunt observed, through new and improved microscopes, how the bacteria only thrived, deprived of the direct and energetic, ultraviolet light. Like in today´s clinical trials, they worked with ...

Coronavirus and Vitamin D: in the Sun and Air during the 1918 Influenza Pandemic

During the 1918 influenza pandemic, some nurses fell ill, while others did not. Was it Vitamin D? It is clear from recent reports that doctors and nurses in hospitals are at high risk of contracting Covid-19. A century ago, during the 1918 pandemic, medical staff were just as vulnerable to influenza. One of the biggest problems back then was a shortage of nurses. As they fell ill, patient care deteriorated, and hospitals began turning patients away. However, it was a different story at an ...
