The rainy season has finally arrived in the Kanto region. Usually, around the end of the rainy season, the number of emergency medical calls due to heat stroke increases rapidly. Last summer was the hottest summer in history, with record high temperatures recorded in many parts of Japan and a record number of extremely hot days in central Tokyo. In the summer of 2023, more than 90,000 people were transported to emergency rooms due to heat stroke, and 1,106 people died. So what are the predictions for this summer? It is expected to be as hot or hotter than last year. Therefore, if no measures are taken, the situation will be similar to the summer of 2023. If ambulance utilization rate reaches 100% due to an increase in emergency calls due to heat stroke, there will be delays in emergency response to traffic accidents and serious trauma and illnesses such as myocardial infarction and cerebral infarction, which may result in the loss of lives that could otherwise be saved. If you can reduce the number of emergency calls due to heat stroke by protecting yourself from heat stroke, you can indirectly help others. In the spirit of "One for all, All for one," please take precautions against heat stroke this year, both for yourself and for everyone else.
