Summer's Biggest Danger: Critical Warning Issued on Dehydration for Over-70s

Summer heat waves and drought increase health risks, with experts highlighting a heightened danger of dehydration, particularly for the elderly. As people age, their body's water content decreases, and the sensation of thirst weakens. By age 70, body water can drop to 50% from around 60% in one's 30s, making older individuals less likely to recognize when they need to drink.

"It is vital to consume water regularly without waiting to feel thirsty," advises Internal Medicine Specialist Uzm. Dr. Burak Uzel. While normal daily fluid intake is about 30 milliliters per kilogram of body weight, hot weather increases fluid loss through sweating. Uzel cautions that diuretic beverages like tea, coffee, and alcohol do not substitute for water and can worsen dehydration.

Uzel recommends increasing fluid intake during periods of sudden temperature rises, fever, excessive sweating, diarrhea, vomiting, air travel, and after intense physical activity. He also addressed the common term "air conditioning sickness," stating it has no medical basis. However, he noted that air conditioners can reduce humidity, leading to dry mouth and nose, respiratory irritation, and muscle aches.

Furthermore, Uzel stressed the importance of regular ventilation in air-conditioned spaces to prevent the spread of viruses and bacteria. While Legionnaires' disease is rare in home split systems, it is more commonly associated with central air conditioning in large buildings. For safe air conditioner use, he advises regular filter maintenance, setting temperatures between 24-26 degrees Celsius, avoiding direct exposure to airflow, and ensuring periodic natural ventilation.
