Along with exercise, comes the thought of rest. Incidentally, the person who exercises most is the one who is able to rest best. The Bible says, “The sleep of a laboring man is sweet.” Ecclesiastes 5:12.
Rest is important for all parts of the body, including the stomach; but the brain and nerves profit from it most. Sleeping is the best medicine for tired nerves and aching muscles.
To rest well, a person must be warm and comfortable. A bed should be firm, up off the cold floor, and of a type that can be easily cleaned. It is well to place the bed and bedding out in the sun for several hours at least once a week.
Eight hours of sleep each night is a good amount for most adults. Children should have more. During the first year a baby usually needs about sixteen to twenty hours of sleep a day. In his second year your child should sleep from twelve to fourteen hours. As he grows older, he can perhaps get along with ten hours of sleep, but he should have a rest in the afternoon. Many adults find that a midday rest of half an hour is a big help in increasing their health.
BREATHE DEEPLY OF FRESH AIR
Oxygen is the most vital thing the body, and is obtained by breathing. One can live many days without food, and many hours without water; but one can only live six or eight minutes without breathing.
The part of the body which needs oxygen the most is the nervous system. The brain and nerves suffer permanent damage if a person does not breathe for from six to eight minutes.
A bad habit many people have is that of shallow breathing—not filling up the lungs when they breathe. Disease in the lungs almost always occurs in those parts of the lungs which are not used because of shallow breathing. To fill the lungs, one must use not only the chest muscles, but also the muscles of the abdomen.
Deep breathing should be practiced several times a day, preferably outdoors. Belts or other tight clothing around the abdomen interfere with proper breathing. Having good posture by standing straight and sitting up straight, will help your lungs to work properly and will also help your bony. Skeletal system
The kind of air we breathe is also important. Many germs, too small to be seen, can be carried in the air, and often cause disease. Germs thrive, grow well, in stale, damp air found in houses that are closed up with many people in them. Germs do not live well in fresh air and sunshine. In fact, sunshine kills germs. Houses should have windows that allow air to pass easily in and out, especially in the sleeping rooms, and in the kitchens. General cleanliness also helps the air. If stool, garbage, and other trash is allowed to stand on top of the ground, the air will be contaminated and bad. The best and purest air is found in the country, away from the smoke, fumes, and smells of the city.
DRINK PLENTY OF WATER
The fact that three-fourths, or 75 percent, of the weight of the body is water shows how important water is. Water is needed for all the body, but especially for its work of passing out poisons The body takes in food and water, and passes out what it does not need, as stool and urine The kidneys, however, do even more than this. They are the special cleansing filters for the blood, and water is necessary for this |job. One can usually tell the activities of the kidneys by the colour of the urine. Dark urine means the kidneys are passing lots of waste from the blood. One should drink enough water each day so that it has one voiding it does like water. One is likely to get disease of the kidneys if he does not drink enough water Six or eight cups of muter per day is a good amount to drink. It is better to drink this water between meals and not with the meals.
In addition to helping the kidneys, water also helps the skin t0 sweat well, which helps the body to get rid of waste products or poisons.
Drinking unclean water is dangerous. Germs live well in water. Stool, urine, and many other things that cause disease, are often washed into water by the rain.
Most cities treat their water with chlorine substances to kill the germs but people who get their water from other places must take
Care. Water from well or springs is often good provided water from the surface of the ground cannot get into it. But to be truly safe outside the cities, all drinking water should be boiled for at least five minutes. It should then be kept in a covered container so flies and dirt cannot get into it.
