The number of heat stroke patients has increased more than three times in the last five years, highlighting its seriousness. Heat stroke is a severe heat-related illness that can cause changes in consciousness and seizures as body temperature exceeds 40 degrees Celsius, and can even be fatal. Elderly people are particularly vulnerable to heat stroke due to their impaired thermoregulation function. Early symptoms may include excessive fatigue, headache, and dizziness, which can quickly worsen if ignored. During a heat wave warning, minimize going out, and if necessary, use early morning or late evening hours.
