Excerpt from The Dietetic and Hygienic Gazette, Vol. 23: January, 1907 When the ability to sleep is weakened sleep becomes light and fugitive. As a rule broken sleep occurs in persons with an irri table vasomotor system, who blush easily, and in whom the pulse quickens on slight provocation, and also in those of emotional temperament who are easily provoked to grief or laughter. These patients will say that they have not slept a wink all night; that they have heard the clock strike every hour; but if watched it will be found that they sleep lightly at intervals during the night. Complete insomnia rarely occurs, and when it does death takes place in eight or ten davs. Mental overwork produces insomnia, probably owing to overdilation of the cere bral vessels, which fail to contract through temporary paralysis. Insomnia, the result of physical overwork, is probably due in part to the same cause and in part to the in creased action of the heart, which fails to subside as rapidly as the pressure. Oliver has shown that under normal conditions the blood pressure returns to normal much more rapidly than the pulse. Emotions cause sleeplessness by raising the blood pressure, the arterioles contract ing. In anemia insomnia is due to want of tonicity of the vessels, the blood which gravitates to the lower extremities in the erect position flows to the brain on lying down; these patients may complain that while standing or sitting they are sleepy, but on lying down they become wide awake. In these cases a little food in the stomach with strychnin or digitalis will often give a good night's rest.
