The number of hospitalizations in the public health network has dropped by 51% in the last 10 years: it decreased from 397,333 in 2000 to 192,601 in 2010.

Asthma is a respiratory disease that has no cure, but if controlled, the asthmatic can have a normal life based on medicines anti-inflammatory drugs and bronchodilators, which are pharmacologically active substances - by promoting bronchial dilatation - and popularly known as "bombinhas". The cold and dry weather of this season is conducive to the spread of the disease, which can lead to respiratory attacks and increase the demand for emergency care.

According to the pulmonologist Carlos Carvalho, there is an increase of about 30% in the number of cases attended at the Hospital at this time of year. "The dry weather, smoke particles, irritating gases, chemicals and potential allergens in the atmosphere aggravate asthmatic crises," he says.

"In winter, there are several aggravating factors that increase asthma attacks. Avoiding exposure to cold, dry weather with low relative humidity helps reduce the incidence of asthma attacks during this time."
In addition to allergen , stress at work can increase the chances of developing asthma by as much as 40 percent, according to research by the University of Heidelberg in Germany. The researchers came to this conclusion through eight-year follow-up of more than 5,000 people between the ages of 40 and 65.
