[The effect of weather and climate on the healthy and ill individual].

It has been known for thousands of years that changes of the weather and climate influence in a significant way man in health but in particular in disease. In the submitted paper the author describes different mechanisms of action of the mentioned factors, risk situations and also possible ways how to prevent adverse influences or to reduce at least their effect. In the conclusion the author mentions problems of biometeorological forecasts and the importance to take into account also extra-terrestrial influences. It is remarkable that less attention is paid to detailed, in particular experimental research, than corresponds to the serious character of disorders and their impact on the health status of the population.
