_Insomnia._—This is another symptom of overwork. The mind, worried and harassed all day, retires at night to struggle in the darkness and solitude with worries, forebodings, doubts, and regrets, which now assume gigantic and fantastic shapes. In this case the insomnia is due to faulty habits of mind. Another form of insomnia is caused by intellectual work being carried on at night until time for retiring; the mind is then so fully saturated with the subject that it is unable to throw it off on going to bed. Whatever be the cause of the insomnia, it soon becomes a fixed habit, and, whether it is a case of laying awake a long time before sleep comes, or waking up at a regular hour toward morning,—and it is a curious fact that the habit of waking up recurs at almost precisely the same hour in the morning,—the longer this habit of insomnia is indulged in, the more difficult it is to break it up. _Nervousness._—This is a well-known sign of overwork, which shows itself in intense nervousness and irritability. Everything jars on the nerves. The woman gives way to her emotions, over which she loses control. To keep placid when overworked to the limit of physical endurance requires a stolidity of soul and lack of nerves only known to the North American Indians, and perhaps the Japanese, and it matters not what the kind of overwork is, whether business, pleasure, or charity. =Nature’s Restoratives.=—The proper division of the day is eight hours to be allotted to work, eight to sleep, and the remaining period of eight hours is to be divided among the various methods of refreshing body and mind—the toilet, eating, rest, and recreations. Not only are rest, recreation, and sleep in proper proportions essential to the health of the body, but they are equally essential to the quantity and the quality of the output of work. From them result a feeling of physical well-being, an exuberance of animal spirits which go into the work. The perspective is more accurate, the judgment is clearer, and the creative power is greater. Work goes of itself with a swing. Happiness is an expansive quality, that makes itself felt throughout the entire body, but its effects are most manifest in the mental power. The mother who so honestly works and plans for the good of her family as to give herself no time to rest after her physical efforts is in such an exhausted condition as only to be able to give them the tired and critical side of herself for daily association. There are few human achievements much finer than to make human beings happy, and this power woman is endowed with to a very large extent.
