Health risks increase with seasonal changes in water exposure and temperature

Health experts are highlighting seasonal risks related to water exposure and temperature changes. Otitis externa, commonly known as ‘swimmer’s ear’, is an inflammation or infection of the outer ear canal. According to otolaryngologist Diego Farias, frequent water exposure can remove protective earwax and alter the pH of the ear canal, creating conditions for microbial growth. This condition is not limited to swimmers; anyone exposed to water in rivers, pools, or beaches can be affected, especially during hot, humid periods.

Additionally, cold weather can impact blood pressure. Dr. Rosangeles Konrad explains that low temperatures trigger vasoconstriction, a process where blood vessels contract to preserve body heat. This increases resistance to blood flow, potentially raising systolic pressure by 5 to 30 mmHg and diastolic pressure by 5 to 15 mmHg. This physiological response poses higher risks for elderly individuals and those with existing cardiovascular diseases. Lifestyle changes during winter, such as reduced physical activity and increased sodium intake, can further exacerbate these risks.
