Evening Republican, Volume 21, Number 138, Rensselaer, Jasper County, 27 June 1917 — Rising Curve of Human Energy. [ARTICLE]

Rising Curve of Human Energy.

As a matter of health, it will be much better to begin the day earlier and end It Earlier. Humanity has a definite cycle of physiological changes that take place during the twenty-four hours. In the early morning, temperature, pulse and respiration are lowest, but begin to rise. They reach a maximum in the early evening hours, between four and six. and then begin to descend again. It is on the rising curve of human energy that the day’s work ought tn be done. Rest should be as far as possible during the hours when the cycle of energy is on the descent. The proposed scheme for daylight saving would bring us back to be more in accord with the human physiological cycle In. the twenty-four hours than Is true at present.
