Health and Light [Pocket Books New York 1976]
by John N. Ott:
Dicusses the effects of natural and artificial lighting on human beings, animals, and plants. Light is a type of "nutrient", and affects the endocrine system. Ott found that different types of artificial lighting affect the gender and presence of fish eggs, and that specially developed strains of cancer prone mice kept under pink and white fluorescent lighting develop cancer sooner that control mice kept under natural daylight. These results were at first criticized and rejected. Finally, papers describing this research were published as part of the Annals of the New York Academy of Sciences. Since that time, study of the biological effects of lighting has become a science. Full spectrum and natural lighting has now been shown to be associated with increased productivity and improved health.
