This chapter deals with institutions and professionals that used sun treatments, such as doctors and scientists. The medical profession struggled to control the new treatments largely because it could not close ranks around a set of principles. With a sun-starved public, sunshine began going where before it had never been. Clinicians struggled to identify how to prescribe treatment with lamps, which had to shine straight overhead because any angle limited light's ability to penetrate the surface layers of the skin and therefore decreased its effectiveness. Sunlight therapy for tubercular patients had become the peak of responsible care, and state governments proved willing to help deliver it. The raised public and medical interest in sunshine took children from their toxic homes and exposed them to a vitalizing environment. Generally, the sun therapy had reached hospitals and zoos, and had cured the sick and fortified the feeble.
