During the June‑to‑September winter season, Paraíba experiences lower temperatures and increased rainfall. Health experts say the cold and humidity aggravate respiratory conditions such as allergic rhinitis, eye irritation, conjunctivitis and asthma.
Allergist Priscila Duarte explains that cold wind and indoor moisture trigger hyper‑reactivity of the nasal passages and bronchi, leading to sneezing, nasal obstruction, itchy eyes and asthma flare‑ups. Veterinarian Ana Carolina Ataíde adds that mold and dampness can also cause asthma in pets, noting symptoms like labored breathing and open‑mouth respiration in cats.
The articles advise residents to monitor indoor humidity, clean mold‑prone areas regularly, and seek medical or veterinary care promptly if symptoms appear.
