■ Emergency Transport for Heatstroke Hits Record High in 2025: Items Cooling Large Body Areas are Effective against Heat
Due to severe heat waves in recent years, the number of people transported by ambulance for heatstroke is increasing. The Ministry of Internal Affairs and Communications announced that the number of transported individuals in Reiwa 7 (2025) reached 100,510, the highest since tracking began (*1). The government designates April 1st to September 30th every year as an 'Intensive Heatstroke Prevention Campaign' period, and the Japan Sports Agency is also urging the implementation of measures to prevent heatstroke accidents during sports activities (*2).
As one heat countermeasure, lowering skin surface temperature to cool subcutaneous blood, thereby suppressing a rise in core body temperature, is well known. In particular, it has been reported that 'cooling a wide area' of capillaries spread throughout the body is more efficient than methods that only cool large arteries (*3). Therefore, items that can directly cool a wide area of the body are considered an effective method in hot environments.
