Really hot. A dangerous heat wave has hit Western Europe. Yesterday, the UK recorded its highest ever June temperature at 36.1 \u00b0C (about 97 \u00b0F). But as the weather app on my phone confirmed, it <em>felt like<\/em> 39 \u00b0C.<\/p>\n<p>It\u2019s frightening that we are seeing such temperatures in the UK in June. According to the Met Office, the country\u2019s national weather and climate service, <a href=\"https:\/\/www.metoffice.gov.uk\/research\/climate\/maps-and-data\/location-specific-long-term-averages\/gcpv7fnqu\">June temperatures peaked at an average 19 \u00b0C<\/a> (66 \u00b0F) in England between 1991 and 2020. Across Europe, the heat wave is likely to cause <a href=\"https:\/\/www.lshtm.ac.uk\/newsevents\/news\/2025\/climate-change-driven-summer-heat-caused-16500-additional-deaths-across-europe\">thousands of deaths<\/a>. There will be other awful consequences for agriculture, infrastructure, and the health system.<\/p>\n<p>But this week I want to look at what the heat does to our minds and brains. Personally, I\u2019ve found it almost impossible to think straight. The heat is distracting and my mind is foggy. I dread to think about the conditions of people who work outdoors, in even hotter regions.<\/p>\n<p>It\u2019s not just exhaustion and confusion. The effects of heat on the brain can be deadly. And researchers are still trying to figure out why.<\/p>\n<p>Studies have confirmed that as temperatures rise, people seem to get more irritable and <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC11477092\/\">more violent<\/a>. Most of these studies are based on associations, though. It\u2019s difficult to directly study how a heat wave might affect our thinking, says Catherine Thompson, a cognitive psychologist at Liverpool Hope University.\u00a0<\/p>\n<p>She has been studying the effects of extreme heat on firefighters instead.

But they\u2019d experienced just 15 minutes of intense heat exposure. Thompson doesn\u2019t know what the effects of living through a days-long heat wave might be\u2014or how long they\u2019ll last. Figuring that out might involve shipping cognitive test kits to thousands of people during the few days\u2019 notice of an impending heat wave. \u201cMy guess [is] that no one\u2019s done it because it\u2019s just so difficult to do,\u201d says Thompson.\u00a0<\/p>\n<p>Still, researchers can learn about some of the impacts of heat waves through studies after the fact. And those studies suggest that the heat seems to have more disastrous outcomes for people with mental-health disorders.\u00a0<\/p>\n<p>Those outcomes become apparent when temperatures rise above what is considered typical for a given region. \u201cThere seems to be a correlation where the hotter it gets, especially during the hottest times of the year, the worse the mental-health outcomes,\u201d says Joshua Wortzel, who directs the Heat-Mind Lab at Hartford HealthCare in Connecticut.<\/p>\n<p>In <a href=\"https:\/\/www.thelancet.com\/journals\/lanplh\/article\/PIIS2542-5196(23)00104-3\/fulltext\">a study published in 2023<\/a>, Emma Lawrence at the University of Oxford, who studies the effect of climate change on mental health, and her colleagues reviewed the evidence linking mental-health outcomes to ambient outdoor temperatures.
