This suggests we live in our modern society with bodies that are still used to the natural environment, he writes in the book, because“genes cannot change over just a few hundred years”.
28、The science behind the research studies he presents in the book makes a convincing case that forest bathing is an effective method for reducing stress in todays world. Now city planners are becoming increasingly aware of the importance of nature and are creating new kinds of “parks”out of empty spac

Finally, after World War , there were so many people livi
