Brazil respiratory health risks rise with spring weather changes

The arrival of spring in Brazil is bringing an increase in respiratory issues, including allergic rhinitis, asthma, and sinusitits. Environmental changes such as temperature fluctuations, variations in humidity, and the dispersal of pollen are primary triggers for these conditions.

In southern regions, pollen from grasses and trees plays a significant role. However, in the Southeast, Midwest, North, and Northeast, the increase in symptoms is largely attributed to indoor allergens like dust mites and fungi, alongside urban pollution and smoke.

Vulnerable groups, including the elderly and children, are at higher risk. For the elderly, sudden weather shifts can exacerbate chronic obstructive pulmonary disease (COPD) and asthma. For children, spring also brings a risk of viral infections such as hand-foot-and-mouth disease, chickenpox, and measles.

Health experts recommend maintaining clean, well-ventilated environments, staying hydrated, and using saline nasal washes to mitigate symptoms. It is advised that individuals with chronic conditions do not modify their medication without professional guidance and seek immediate medical attention if they experience intense or sudden shortness of breath.
