Health experts warn of heat‑related risks and sun‑protection measures

Rising summer temperatures increase the risk of sleep disruption, cardiovascular strain, skin cancer, lymphedema and heat‑related illnesses such as heat exhaustion and heatstroke. Neurology, dermatology and cardiology specialists across Turkey and the United States advise staying hydrated (at least 2–2.5 L of fluid per day), avoiding outdoor activity between 10:00 and 16:00, wearing light, breathable clothing, wide‑brimmed hats and sunglasses, and keeping living spaces cool and well‑ventilated. Sun‑protection recommendations include using broad‑spectrum sunscreen with at least SPF 30, applying the correct amount (the “two‑finger rule” for face and neck), re‑applying every 2–3 hours or after swimming or sweating, and protecting infants, the elderly, people with chronic illnesses and those with post‑cancer lymphedema. Early signs of heatstroke—body temperature above 40 °C, confusion, rapid pulse, nausea, or loss of consciousness—require immediate cooling, removal of clothing, cold compresses and emergency medical assistance. Proper skin care, adequate sleep environment and regular monitoring are essential to prevent long‑term health impacts during heatwaves.
