In Brazil, the dry season occurring between May and October in the Central-West and Southeast regions is presenting significant health risks. Low humidity and increased air pollutants are expected to cause skin irritation, dryness, and dermatological issues. 

Medical experts have also warned of respiratory risks, noting that dry air can lead to coughing, hoarseness, and nasal bleeding, while potentially exacerbating conditions such as asthma, rhinitis, and chronic obstructive pulmonary disease (COPD). Vulnerable populations include children, the elderly, and those with existing cardiovascular or respiratory diseases. 

To mitigate these effects, health professionals recommend high levels of hydration, the use of topical moisturizers, avoiding intense physical activity between 10:00 and 17:00, and using sunscreen.
