■ Record-High Heatstroke Emergency Transports in 2025: Cooling Large Areas of the Body is Effective

Due to recent extreme heat, the number of emergency transports due to heatstroke has been rising. The Ministry of Internal Affairs and Communications reported that in fiscal year 2025, there were 100,510 such cases, the highest since records began. As a countermeasure, cooling the skin surface to lower subcutaneous blood temperature is known to be an effective way to suppress body temperature rise. Research suggests that cooling a large surface area of the body is more efficient than cooling only major arteries, making products that can cover wide areas highly effective in hot environments.

■ 'ZAMST COOL SHADER' Series Re-released Following Popularity as a Sports Heat-Management Item

Launched in 2020, the 'ZAMST COOL SHADER' is a hooded poncho that provides an immediate cooling sensation simply by wetting, wringing, and shaking it. Its ease of use and UV protection have made it a staple for sports events, outdoor spectating, and leisure. With over 100,000 units sold cumulatively by 2025, it has become a popular choice for both adults and children. In response to requests for a more active-friendly design, the 'ZAMST COOL SHADER Active Vest' was introduced in 2025. For the 2026 models, both products have been updated to block approximately 74% of near-infrared rays to further improve comfort during sports activities in the heat.
