Air conditioning health risks and hydration tips highlighted amid soaring summer temperatures

Air‑conditioning systems are widely used to relieve soaring summer heat, but medical experts warn that prolonged exposure can cause a range of health problems. Dry skin, eyes and mucous membranes are common, with clinicians noting that “climate‑air extracts moisture from the air, accelerating water loss from the skin” (Dr. Opel Baker). Low humidity can also irritate the nose and throat, trigger nosebleeds, worsen asthma and increase the risk of respiratory infections if filters are not cleaned regularly. In cars, the recirculation mode can raise cabin CO₂ levels, leading to fatigue and reduced concentration, and a neglected cabin filter may spread dust, pollen and mold. Experts advise keeping filters clean, limiting recirculation time, setting indoor temperatures no more than 6‑8 °C lower than outdoors, and staying well‑hydrated.

Hydration advice complements the cooling measures. Traditional drinks such as Turkish ajran, rich in electrolytes, are recommended for efficient re‑hydration, while research shows milk‑based beverages retain fluid longer than plain water. Seasonal fruits like watermelon and melon, with over 90 % water content, provide natural hydration and electrolytes. Nutritionists caution that the “two‑litre‑per‑day” rule is not universal; fluid needs depend on weight, activity and temperature, with a guideline of about 35 ml per kilogram of body weight. Over‑drinking can dilute sodium, so balanced intake of water, fruits, and electrolyte‑rich drinks is advised.
