When wet-bulb temperatures exceed 35°C, the body is no longer able to use sweat to regulate its temperature, resulting in overheating and, over time, death. There have been at least ten events that have [exceeded a wet-bulb temperature of 35°C](https://theprepared.us3.list-manage.com/track/click?u=2e2c86e49a5f6d1fd1ab7ce70&id=14cfe42562&e=2316f6ec45), and as the earth warms, they’re expected to occur more and more frequently. In [a recent study on human health in 35°C environments](https://theprepared.us3.list-manage.com/track/click?u=2e2c86e49a5f6d1fd1ab7ce70&id=7010a45328&e=2316f6ec45), participants had to “swallow a tiny radio telemetry device encased in a capsule that measured their core temperature while performing tasks mimicking basic activities of daily life, until they could no longer maintain their core temperature without overheating.” - related to [[climate change requires action regardless of cause]].
