When you jump out of bed, throw back the covers and turn them over the foot of the bed, so that the air and the sunlight can get at every part of them and make them clean and fresh and sweet to cover you at night again. Though you may not know it, all night long, while you have been asleep, your skin has been at work cleaning and purifying your blood, pouring out gases and a watery vapor that we call _perspiration_, or _sweat_; and these impurities have been caught by the sheets and blankets. So after a bed has been slept in for four or five nights, if it has not been thrown well open in the morning, it begins to have a stuffy, foul, sourish smell. You can see from this why it is a bad thing to sleep with your head under the bedclothes, as people sometimes do, or even to pull the blankets up over your head, because you are frightened at something or are afraid that your ears will get cold. Your breath has poisonous gases in it, as well as your perspiration; and the two together make the air under the bedclothes very bad. Now you are ready to wash and dress. But before you do this, it is a good thing to take off your nightdress, or turn it down to your waist and tie it there with the sleeves, and go through some good swinging and "windmill" movements with your arms and shoulders and back. (1) Swing your arms round and round like the sails of a windmill; first both together, then one in one direction, and the other in the other. (2) Hold your arms straight out in front of you, and swing them backward until the backs of your hands strike behind your back. (3) Hold your arms straight out on each side, clench your fists, and then smartly bend your elbows so that you almost strike yourself on both shoulders, and repeat quickly twenty or thirty times. (4) Swing your arms, out full length, across your chest five or ten times. (5) Swing forward and down with your arms stretched out, until the tips of your fingers touch the floor. (6) Set your feet a little apart, swing forward and downward again, until your hands swing back between your ankles. [Illustration: STARTING THE DAY] When you come back from these down-swings, bend just as far back as you can without losing your balance, so that you put all the muscles along the front of your body on the stretch; and then swing down again between your ankles. This will help to tone up all your muscles, and limber all your joints, and set your blood to circulating well, and give you a good start for the day. III. BATHING AND BRUSHING Now you are ready to wash and dress. You can easily take off the gown, or garments, that you have worn during the night; but there is one coat that you cannot take off--one that is more important and useful and beautiful than all the rest of your clothes put together, no matter of how fine material they may be made, or what they have cost.
