=Mountain and Sea Air and the Injury from Over-bathing.= The seashore is properly a great national playground during the heat of summer. Evaporated spray leaves a trace of salt in the air which, with the salt of the ocean, seems to be beneficial to many. Likewise there is no condition of life that is not benefited by the pure air of the wooded mountains. Those of moderate vigor may build up and maintain high vitality by continuous bathing in the cool, pure waters of mountain lakes and streams, but to many daily swimming in either fresh or salt water, except that it be for a mere dip and right out again, that is so cold as to be painful to the delicate sensations of the skin, is extremely debilitating to all bodily functions. Be moderate. =How to Find the Climate You Seek.= At sea level in the tropics heat and moisture combine to produce great physical discomfort. But even under the equator it is possible to escape the tropical heat of low levels by ascending four to six thousand feet, as can be done in some places in Porto Rico and Cuba. Most of the capitals of South American countries are located at altitudes of five to ten thousand feet; and Brazil is planning to abandon her capital at sea level and move the administrative machinery of government from the splendid city of Rio de Janeiro to a mountain location in the interior. Any region of the Alleghany system of mountains above a thousand feet elevation possesses climatic conditions of therapeutic value. Illustration of this fact is seen in the success of the noted sanitaria in the Adirondacks, and in the mountain regions of North Carolina and Virginia, and in the northern part of New England. These sections are especially frequented by persons suffering from pulmonary diseases, or from nervous exhaustion, many of whom find not only relief but cure. Cool and healthful conditions of temperature may be found during the summer along the ridges and on the peaks of the entire mountain system that extends from North Carolina northward through Virginia, Pennsylvania, New York, and New England. The advice of one’s physician should be sought, if one is ailing, before determining between the seashore and the mountains, but in general those suffering from diseases of the respiratory organs are better located in the high levels, remote from the humid air of the ocean. In winter Bermuda, Florida, Porto Rico, Cuba, the southern part of the Gulf States, much of Southern California, and Hawaii have balmy climates that permit of outdoor life without temperatures too high to be comfortable. Hawaii and Bermuda have mild climates not only during winter but throughout the entire year. The Riviera on the Gulf of Genoa and the beautiful Lake region of Italy enjoy the balmy air of the Mediterranean and are protected from the cold winter winds by the Alps.
