Value of Sunlight
The value of the sunlight in respect to health has been recognized from time immemorial. Direct rays of the sun are essential in the development and expression of animal and plant life. The sun’s rays are Nature’s greatest germicide. They destroy almost all forms of germ life. Most of the chemical reactions are hastened or induced by the action of light. Light prevents or retards the development of the lower forms of life but promotes the growth of the higher forms.
