Debility
A general relaxation of the nervous system is the source of numerous disorders, and requires a treatment as various as the causes on which it depends. In general, gentle heat possesses both stimulating and strengthening properties, and this is best communicated by a warm bath, which instead of relaxing will invigorate the whole frame. Diet must also be attended to; and weakly persons should be careful to eat light and nourishing food, and plenty of nutritious vegetables. New laid eggs, soup, strong meat-broth, and shell-fish are also very nourishing. Clothing should be accommodated to the climate and changes of weather, so as to preserve as much as possible a middle temperature between cold and heat. Invalids of this description require longer and less disturbed rest than persons in perfect health and vigour; labour and exercise adapted to their habits and strength, a clean but not too soft bed, an airy and capacious apartment, and particularly a calm and composed mind, which last possesses a most powerful influence in preserving health and life, for without tranquility, all other means will be ineffectual.
