Climate plays a large role in causing allergy. The interaction of temperature, humidity and barometric pressure is important in causing or increasing the symptoms of allergy. It appears that allergic diseases, especially asthma, tend to be adversely affected by high humidity, by sudden temperature changes (particularly from warm to cold) and by drops in the barometric pressure.<\/p>\n

Dust allergy is usually influenced by the season in which the trees pollinate, which causes the allergic pollen grains to be produced. Windy days are responsible for making the pollen grains airborne and spreading them through the environment. The susceptible individuals, on inhaling these allergens, tend to develop allergic symptoms. Dust, pollutants and other allergic elements are suspended in the atmosphere during windy and rainy days.<\/p>\n
Fungi and moulds are airborne during rainy days. Increased humidity during rainy days is also responsible for increase in allergic symptoms both in the lungs, ear, nose, throat, eyes as well as skin. Hot and humid weather is also responsible for fermentative changes in food, increase in the population of mosquitoes, houseflies and other insects which can increase incidence of food allergy and insect bite allergy.<\/p>\n
Change of seasons from summer to winter and vice versa with changes in temperature is responsible for increase in the population of viruses which increase susceptibility to viral infections – like that of eye (Eye-flu), nose (Rhinitis), sinuses (Sinusitis) lungs (Bronchitis), digestive system (Gastroenteritis) and skin infections (Herpes Zoster).<\/p>\n
Many symptoms of asthma will be aggravated in the cold weather as well as in the early morning hours which awakens the individuals from their sleep. Conversely, many asthmatics feel better late in the afternoon and evening hours.<\/p>\n
Thus, change of seasons is responsible for onset of new and relapsing cases of allergies of different types.<\/p>\n","protected":false},"excerpt":{"rendered":"
