Human health depends on homeostasis of the organism which is ecological and physiological function.
Occurrence of a lot of diseases has seasonal characteristics and the patient shave different abilities to adapt and are most vulnerable to weather change.
Certain meteorological conditions for respiratory and digestive diseases sensitive to climate could lead to relapse or severity of the diseases and serve as conditions to develop the diseases.
Recently with improvement of material and cultural level the interest of the people for health and longevity has been increased and accordingly medical meteorological studies have been actively conducted.

Males were at higher risk of bronchitis, pneumonia and bronchial asthma than female and with regard to age, bronchitis and pneumonia were more at the age of 1~6 years and bronchial asthma at the age of 40~60 years.
Bronchitis mostly occurred in spring (January to April), pneumonia in spring (March to May) and summer (September), and bronchial asthma in spring (March to May), summer and autumn (August to October).
Temperature had slightly negative correlation with bronchitis and pneumonia, and atmospheric pressure had slightly positive correlation with bronchitis.
As for occurrence of some respiratory diseases according to the meteorological factors, bronchitis mostly occurred at –10 to -5℃ and in atmospheric pressure of 1 016 ~ 1 020hpa.
Pneumonia was mostly prevalent at -10 to 10℃ and bronchial asthma at 0 to 25℃.
Medical weather forecast on the diseases sensitive to the climate should be further improved by clarifying the relationships of disease occurrences with not only meteorological condition for the day but also the day before and with meteorological changes in a day on the scientific basis.
