DRINK PLENTY OF WATER.--Water, and a great deal of it, is desirable at any time during the summer. It should be drunk freely during the day. Lemonade also is good, the slight acid being an aid to digestion. It is best to have beverages cooled only to a moderate temperature. Ice water is not bad, but it would be preferable if it were not at so extreme a temperature. Ice is resorted to only as a convenient means of securing a palatable temperature; the system does not crave extreme cold. Water at the temperature of the air is nauseating, so ice is put into it and the other extreme secured. Sixty degrees is the ideal temperature for drinking water. If this could be conveniently obtained it would be preferred to a greater degree of cold. Not only is it less harmful to the system, but it is more satisfying and thirst-quenching. Water put in bottles and left in a refrigerator until properly chilled is the best way of preparing a summer beverage. When any beverage is sufficiently cold to cause a pain in the head or throat when drinking it the result may be harmful. Cold water poured on the wrist or head has a cooling effect and tends to reduce the ice water habit. If one could afford it, it would be well to drink nothing but mineral water in the summer. Not only does it assure purity, but the gas is an aid to digestion and serves to render the water more palatable. This results in more of it being drunk than if it were flat water, and it is desirable to drink as much water as possible in hot weather. By mineral water I mean carbonated bottled waters intended for table use. Care should be taken that the water is only lightly impregnated with salt. It is much safer to drink a well-known water. The water may not be bottled at the spring or it may be bottled under unsanitary conditions. In many cases mineral water is not all that it should be in cleanliness. Unless one is sure of the purity of a bottled water good hydrant water supplied through the city pipes is safer. In traveling, however, and at summer resorts it would be well to drink nothing but mineral water of a well-known brand. Only by doing this and by being certain that the bottle has not been refilled can one be safe. The supplied on trains and in resorts frequently is not as pure as that supplied in large cities. On the whole, however, mineral water has no particular advantage over ordinary water except that the well-known brands are sure to be pure, and the carbonization makes it more tasty and so increases the amount consumed. It is much safer and more healthful to drink a well-known mineral water than the so-called soft drinks, many of which are unclean and harmful. DISEASES OF WOMEN CHAPTER XXIX DISEASES OF WOMEN
