Summer dehydration risk spikes for older adults

Older people, especially those over 50, face a heightened risk of dehydration during hot weather because aging weakens both the feeling of thirst and the kidneys' ability to conserve water. As a result, symptoms such as dizziness, unusual fatigue, confusion and dark‑colored urine may appear after fluid loss has persisted for several hours.

Urologists Dr José Salvado and Dr Rajesh Patel warn that reduced mobility, certain medications, chronic illnesses and higher blood sugar can amplify the danger. They recommend that seniors consciously drink about two to two and a half litres of fluid each day, even when they do not feel thirsty, and monitor urine colour as a simple hydration indicator. Persistent dark urine, especially if accompanied by blood, pain, fever or nausea, should prompt a medical consultation to rule out kidney, urinary‑tract or liver problems.
