This summer's heat wave has led to an increase in the number of people suffering from heatstroke, with a particularly high proportion of those aged 65 and over. According to research, for every 1 degree Celsius increase in temperature, the mortality rate among the elderly increases by 2.2%. This is because older adults have a reduced ability to physically adapt to climate change. Therefore, during heat waves, it is crucial to maintain a cool environment through measures such as showering, wearing loose clothing, and wearing a hat to regulate body temperature. Adequate hydration is also essential, and it is advisable to avoid caffeine or alcohol consumption.
