SLEEP A PREVENTIVE OF HEADACHE.
A SCIENTIFIC writer says: "Sleep, if taken at the right moment, will prevent an attack of nervous headache. If the subjects of such headaches will watch the symptoms of its coming, they can notice that it begins with a feeling of weariness or heaviness. This is the time the sleep of an hour, or even two, as nature guides, will effectually prevent the headache. If not taken just then, it will be too late, for after the attack is fairly under way, it will be impossible to get sleep till far into the night, perhaps. It is so common in these days for doctors to forbid having their patients waked to take medicine, if they are asleep when the hour comes round, that the people have learned the lesson pretty well, and they generally know that sleep is far better for the sick than medicine. But it is not so well known that sleep is a wonderful preventive of disease—better than tonics, regulators, and stimulants."—Selected.
