Changeable climate therapy or hazard?
Human beings have an in-built adaptability to variations in climate. Exposure to a natural range of atmospheric conditions is necessary for balanced and healthy living. Striking the balance requires some degree of planning for most people. For urban dwellers whose occupations keep them mostly indoors, reasonable exposure to changeable outdoor air can too easily be avoided. For those with a taste for tramping, mountaineering, long distance running or boating, exposure to the elements can become a matter of life or death.
