Coffee affords very little nourishment, and is apt, if drank strong, to occasion tremors of the nerves. It is very bad for bilious constitutions. The calm, phlegmatic temperament can bear it. With a good supply of cream and sugar, drank in moderation, by those who exercise much and take considerable solid food, it may be used without much danger.
Strong green tea relaxes the tone of the stomach, and excites the nervous system. Persons of delicate constitution are almost sure to be injured by it. Black tea is much less deleterious. If used with milk and sugar, it may be considered healthy for most people.
Chocolate, when it agrees with the constitution, is very nutritious and healthy. But it seldom can be used steadily except by aged persons who are very active. It agrees best with persons of phlegmatic temperament; and is more healthy in the winter season than during warm weather.
No kind of beverage should be taken hot—it injures the teeth and impairs digestion.
1347. A few Rules for Health.—Rise early. Eat simple food. Take plenty of exercise. Never fear a little fatigue. Let not children be dressed in tight clothes; it is necessary their limbs and muscles should have full play, if you wish for either health or beauty. Wash very often, and rub the skin thoroughly with a coarse towel.
Wash the eyes in cold water every morning. Do not read or sew at twilight, or by too dazzling a light. If far-sighted, read with rather less light, and with the book somewhat nearer to the eye, than you desire. If near-sighted, read with a book as far off as possible. Both these imperfections may be diminished in this way.
Clean teeth in pure water two or three times a day; but, above all, be sure to have them clean before you go to bed.
Have your bed-chamber well aired; and have fresh bed linen every week. Never have the wind blowing directly upon you from open windows during the night. It is not healthy to sleep in heated rooms.
Wear shoes that are large enough. It not only produces corns, but makes the feet misshapen to cramp them.
