THE NAP AFTER DINNER.

An old adage says, "After dinner thou shalt either rest or walk a thousand steps." Habit, however, has modified this very much; for people nowadays neither rest nor walk; but, if they can, they lie down and slumber. Now, it is true that sleep does not belong to the articles of food. We might despatch the question of the nap after dinner here at once; yet, if it has any influence upon the digestion of food, it is of enough importance to merit a few words.

It was mentioned before, that eating and digestion are a labor. To many it may be the most pleasant labor, to others even the only labor of their lives; but be this as it may, it is certainly a labor for all and every one; and it is important that during the process quiet should be enjoyed. He who thinks he gains by not taking enough time for eating, or he who takes his dinner while working or moving about, loses actually more than he even thinks of winning. The activity without disturbs seriously the activity within. The perspiration on the surface of the body withdraws moisture from the inside of the body to such an extent as to diminish even the saliva in the mouth, so necessary to digestion. Have not all of you had the experience, that when fatigued you feel dryness in the mouth; that you feel as if a piece of dry bread would not pass down, but remain in your throat? And as with the saliva, it is with the other digestive fluids; if there is any want of them, the food we have taken lies in the stomach like stone.

It is therefore desirable to take a short rest before dinner, not to perform any kind of labor whatever during the same, and, above all, not to exercise the body immediately after dinner. Eating is an inward work, and should not be accompanied by any labor without. As an additional proof of what we said above, it may be stated that, as probably many of our readers know already, even in the hottest summer, perspiration diminishes after dinner. This will convince all, that when the digestive apparatus is at work, the outer organs ought to be at rest. Once more, then: before and after dinner we need rest, and it is this rest which renders us indisposed to labor and makes us feel sleepy.

On the other hand, we must take but a short slumber. Those who have accustomed themselves to sleep after dinner, feel that half an hour's slumber is all that is needed, and that they even feel weary if they have slept longer.

The reason of this is, the process of digestion is properly carried on chemically by the food, being dissolved through the gastric juice. This digestion, however, is greatly promoted by the motions of the stomach, which tosses the food about from one side to the other, mixing it entirely, and finally making a large ball of it, whose various ingredients are, as it were, fused together. This process needs rest on our part; during it sleep is sweet and agreeable. But for the further digestion of food, energy is needed, which we have not during that sleep; therefore its want makes our prolonged sleep uneasy, or renders our digestion imperfect. This latter may be felt by every one who goes to bed with a full stomach. His sleep during the first hour is undisturbed and pleasant, because it is favorable to the first stage of digestion. But after that, sleep is very uneasy; weariness and complaints about bad digestion follow, and the imprudent person rises next morning with headache, coated tongue, and indigestion in the stomach.

From what has preceded we may conclude, that a short nap after dinner is conducive to good health; while if taken too long, it will produce the contrary effect. Dizziness in the head and fetid taste in the mouth are sure signs of one's having overslept one's self, and he who has been so imprudent must animate his system—not by liquor, but with a glass of fresh water; or he must, if he feels very heavy, wash with very cold water. For this is the moment when digestion needs activity more than anything else; the above symptoms are the indications, and man should consider them as the summons of nature, who calls to him, "Thou hast eaten and reposed; go, then, to thy labor; this is the time!"

Let every one obey her call, and there will be less sickness.
