Brazil warns of cold‑weather risks for elders and high heart‑attack mortality in young women

Medical experts in Brazil caution that cold and dry weather periods pose heightened health dangers for older adults. Geriatrician Dr. Tiago Ferolla explains that reduced physiological resilience can lead to worsening respiratory conditions such as asthma, COPD and bronchitis, increased risk of infections, dehydration, skin and mucous‑membrane drying, and mental‑cognitive changes. He advises families to monitor signs like excessive sleepiness, confusion, reduced fluid intake, persistent cough, and sudden weakness, and to seek early medical care. Preventive measures include encouraging regular fluid consumption, keeping indoor air humidified, promoting light physical activity, ensuring safe sun exposure, and keeping vaccinations up to date.

A separate study by the São Paulo State Society of Cardiology shows that Brazilian women up to 45 years old experience higher mortality and poorer outcomes after heart attacks compared with men of the same age. Women often present atypical symptoms—intense fatigue, shortness of breath, nausea, abdominal discomfort, or general malaise—leading to delayed treatment. Contributing risk factors include obesity, hypertension, diabetes, smoking, sedentary lifestyle, family history and stress. Physicians stress early cardiovascular screening, blood‑pressure control, metabolic monitoring and healthy lifestyle adoption to reduce risk.
