Japanese researchers from Hiroshima University have developed a new type of cooling vest for sports athletes that may help them compete safely in sweltering summer conditions.
Background:
The 2020 Tokyo Olympics will be held in the hot and muggy Japanese summer where the ambient temperature is expected to be above 33 degrees Celsius.
Because the human body temperature is usually around 37 degrees Celsius, a concern arises if it increases over 40 degrees Celsius. Dehydration, decreased performance and decreased brain function are the dangers when the core body temperature climbs too high.
Cooling Vest:
The cooling vest is filled with ice packs and features a collar that can also cool the neck.
The aim is to cool the athletes' upper-body skin which can decrease heart rate and temperature of their neck and skin.
The research is not just applicable to athletes but to people that exercise in hot conditions.
