The Skogluft Effect


The Skogluft effect has been thoroughly documented through 25 years of research. 

In 1987, contact was made with NASA. They were developing the space stations of the future. In connection with this, they were researching how elements of nature can be used to improve the living conditions on board the space stations. The results of the studies showed that nature will play an important role in future space stations where people will live for long periods of time.


The research has been conducted by the Norwegian University of Life Sciences and has been carried out on hundreds of users in offices, hospitals and schools in Norway. The basic research has been conducted by NASA and the result is one of the world's best documented indoor environment studies.

In the radiology department at Oslo University Hospital, Ullevål, sickness

absence fell by 50% and employees reported feeling healthier and more motivated both in their free time and when at work. In classrooms, student and teacher tiredness was reduced by 42% and student concentration levels increased by 23%. 

As of today, there is documentation of the effects in offices, schools and hospitals in Norway.. 

Sickness absence was reduced from 17% to just 5%
