Hi, in this video, we are going to have a look into the health-promoting effect of nature and in particular of woodlands, by the scientific evidences and contributions. First of all, I would like to talk about work done by Dr. Daniela Haluza and Dr. Renate Cervinka, who have done an overview of scientific literature on the benefits of nature and woodlands in human health, well-being and also quality of life. They have revised around 149 peer-reviewed articles and around 30 landmark publications. Main findings of the research of this overview of scientific publications are, that there can be positive effects on physical and psychological health of humans and well-being, and there can be a decline in the pulse rate, also an attenuation of blood pressure and a drop in the salivary cortisol and all these variables are signs and indicators of stress-reducing so that these results show that there can be a reduction of this stress by being and spending time in woodlands. Another main finding is that there is an increase of positive emotions and also, that most studies reported show evidences of positive effects and prevention of stress related diseases. Now,I would like to talk about Shinrin-yoku, which can be translated as forest bathing. In fact, forest bath therapy can be a psychological or medical prescription in Japan. In this country, in Japan there has been a lot of research done since the 1980's trying to give evidences of this forest bath effects in human's health. You will be able to find more information about this research articles in the supplementary material off this video. Now, I would like to introduce two Japanese researchers, who are Dr. Chorong Song and Dr. Harumi Ikei. They have done many research and experiments and they publish a lot of articles giving evidences and they make clear that there is a physiological and psychological effect of nature in humans. Also, they mentioned their work promotes and mentioned that there is an important preventive role in the medicine in the future of all these aspects. So all these aspects can be really important for preventing diseases or psychological problems in the future. Now, I would like to talk about Dr. Liisa Tyrvainen, she has done many research not only in woodlands but also in green environments, and green areas in urban areas. So one of her books is "Benefits and uses of urban forests and trees" and the idea is that forest and trees, probably due to the colors, shapes, and sizes and other traits, they are one of the most prominent elements of natural urban areas. The idea also, is that they can give many benefits to humans and intangible benefits,like for example, aesthetic or psychological benefits and also other type of benefits like for example, the amelioration of climate and the mitigation of air pollution in the cities. So she has done many research and also she has done research together with Japanese researchers and here you have some of the results of a one of her papers. You can see in the graph how, there is a difference between people who has walk and stayed in a forest and people who has made the same in an urban area. So the black line is for the forest experimental part and you see how there's a higher activity of the parasympathetic nervous system in the forest and the people who have been in the forests so that finally, they conclude that walking in the forest environment can promote cardiovascular relaxation. So here with this video, we have seen another example of how nature conservation is important for human well-being.
