Coping with high heat » Yale Climate Connections

If you have ever found yourself overheated, you know how unpleasant it is. But you may not know how dangerous it is – and how much more of this kind of danger we’re facing as the planet warms up.

Those who live where it’s often hot generally know what to do to protect themselves from overheating, though whether they are able to do these things is another matter. Those who live in more temperate places have much to learn – about the effects of high heat for a few hours or a few days and nights, effects both short and long-term, on both bodies and minds; about what makes some more vulnerable than others; and about ways to cope as both individuals and societies.

Here’s one article to spur your interest in such adaptations: Record-breaking heat waves show we need to adapt to the climate crisis now, Beatrice Christofaro, DW, 2022. And, if you are in a position to do something on a larger-than-personal scale, try spending some time with the Global Heat Health Information Network.
