It’s not a secret     1     spending time in nature is good for you. For years, scientists have been detailing how people who live near green spaces have     2    (good) physical and mental health. Practices which have a strong outdoor component     3    (be) popular here in the United States.

My     4    (curious) was aroused when a colleague recently recommended one of our patients to experiment with     5    (walk) barefoot in the grass for a short time each day. A few weeks later, I came across an article that gave a name to that practice—grounding. The idea behind grounding, also    6    (call) earthing, is that humans evolved in direct contact with the earth’s subtle(不易察觉的) electric charge. But we have lost that connection and     7     loss of connection is due to inventions such as buildings, furniture and shoes.

    8    (support) of grounding say this “disconnect” might be contributing to some diseases that are     9    (particular) common in industrialized societies. There is actually some science behind this. Barefoot contact with the earth can produce nearly instant changes     10     various ways, helping to improve sleep, reduce pain, decrease muscle tension and lower stress.
