Athletes at Tokyo 2020 swallowed a electronic pill that measured their body temperature as part of a pioneering experiment. And Team GB athletes are among those athletes who downloaded physiological data from an electronic pill while preparing for Tokyo's extreme heat. But this is the first time that researchers were able to chart athletes' biological activity in real time. The pill, which weighs 1.7g, is swallowed a few hours before competition and passes through the body within 48 hours. The scientists then read core temperature and skin temperature, while also monitoring climatic in-formation including humidity and land and air temperature.
