Milk and Sunlight in an Office
Milk and Sunlight in an Office.
Girl members of the “New Health” Society's staff were made the subjects of a test to ascertain the results of a course of irradiation with artificial sunlight and the inclusion of a regular addition of milk to the daily diet. This was conducted during the spring, a time when the girls would be likely to benefit from such an aid to the restoration of vitality lost during the winter; and such an assumption was endorsed by the success of the experiment.
Each individual was given daily a pint of pasteurised milk, supplied gratis by a well-known dairy company, and exposure to a mercury lamp three times a week. At the end of the period they all testified to increased well-being and vitality, and the report of the medical expert showed in each case increased chest expansion, while in five out of seven cases weight increased, especially those who had been distinctly below their best weight.
This experiment should be of the greatest interest to all concerned in the welfare of office workers, proving, as it does, the improvement in physique, and consequently, working efficiency, to be gained from either an increased milk consumption or the use of artificial sunlight in the winter months, or, better still, both together.
