Spending time in natural surroundings promotes restoration and healing for the sick.

Original passage

The plan of life which God appointed for our first parents has lessons for us. Although sin has cast its shadow over the earth, God desires His children to find delight in the works of His hands. The more closely His plan of life is followed, the more wonderfully will He work to restore suffering humanity. The sick need to be brought into close touch with nature. An outdoor life amid natural surroundings would work wonders for many a helpless and almost hopeless invalid.
