You, who maybe just a month ago were confidently running at a steady pace, now find yourself puffing like an old steam engine, your legs refusing to move the way they should. You wonder: am I getting worse, or is it really just the heat?<\/p>\n<p class=\"ai-optimize-7\">The answer is simple: <strong>it\u2019s physiological<\/strong>. And next time you start worrying that you\u2019re suddenly falling apart, you\u2019ll know that\u2019s not the case.<\/p>\n<h2 id=\"the-internal-thermostat-that-slows-us-down\" class=\"ai-optimize-8\">The Internal Thermostat That Slows Us Down<\/h2>\n<p class=\"ai-optimize-9\">When you run, your body produces heat. A lot of it. According to the <a href=\"https:\/\/journals.lww.com\/acsm-msse\/Fulltext\/2007\/02000\/ACSM_Position_Stand__Exercise_and_Fluid_Replacement.22.aspx\" target=\"_blank\" rel=\"noopener\">American College of Sports Medicine<\/a> (ACSM), up to 80% of the energy generated during a run is dissipated as heat. That\u2019s an incredibly efficient system, considering that humans are built to sweat.<\/p>\n<p class=\"ai-optimize-10\">Sweat is our natural air conditioning: as it evaporates, it cools the skin and lowers core temperature. But when the air is already hot and humid, this process slows down. Evaporation becomes less effective, and your body accumulates heat.<\/p>\n<p class=\"ai-optimize-11\">The result? Your autonomic nervous system sends signals to ease off the effort and protect your body.<\/p>\n<h2 id=\"the-brain-does-its-job-even-if-we-dont-like-it\" class=\"ai-optimize-12\">The Brain Does Its Job (Even if We Don\u2019t Like It)<\/h2>\n<p class=\"ai-optimize-13\">How does this all work? The <a href=\"https:\/\/journals.physiology.org\/doi\/full\/10.1152\/japplphysiol.00910.2004\" target=\"_blank\" rel=\"noopener\">Journal of Applied Physiology<\/a> explains it well: fatigue isn\u2019t just about your muscles\u2014 it\u2019s largely a perception regulated by the brain. When your body temperature gets too high, the brain kicks in with a self-preservation mechanism: it slows down the signals to your muscles to prevent dangerous overheating.<\/p>\n<p class=\"ai-optimize-14\">In short, it\u2019s not that you\u2019ve lost your edge\u2014your nervous system is literally saving your life by forcing you to slow down.<\/p>\n<h2 id=\"learning-to-read-the-signals\" class=\"ai-optimize-15\">Learning to Read the Signals<\/h2>\n<p class=\"ai-optimize-16\">How can you tell if you\u2019re slowing down because of the heat and not because you\u2019re out of shape? Here are some clear signs:<\/p>\n<ul>\n<li class=\"ai-optimize-17\"><strong>Increased perceived effort<\/strong>: running at your usual pace suddenly feels much harder.<\/li>\n<li class=\"ai-optimize-18\"><strong>Higher heart rate<\/strong>: even at an easy pace, your heart rate climbs.<\/li>\n<li class=\"ai-optimize-19\"><strong>Heavy sweating<\/strong> (or sometimes reduced sweating, if you\u2019re already quite dehydrated).<\/li>\n<li class=\"ai-optimize-20\"><strong>Early onset of fatigue<\/strong> compared to what you\u2019re used to.<\/li>\n<\/ul>\n<p class=\"ai-optimize-21\">In these situations, it\u2019s smart\u2014and totally normal\u2014to slow down. Accepting this will save you from unnecessary frustration.<\/p>\n<h2 id=\"this-is-not-the-time-for-a-personal-best\" class=\"ai-optimize-22\">This Is Not the Time for a Personal Best<\/h2>\n<p class=\"ai-optimize-23\">It\u2019s easy to forget that your running performance in summer simply can\u2019t match what it is in spring or fall. Environmental conditions matter\u2014a lot.<\/p>\n<p class=\"ai-optimize-24\">For every degree above 20\u00b0C (68\u00b0F), your 10K time can slow by about 1\u20132%. On longer distances, the impact is even greater. And no, this isn\u2019t about willpower\u2014it\u2019s pure physiology.<\/p>\n<p class=\"ai-optimize-25\">Even elite runners know this: during summer races, they rarely aim for records. They adapt their strategy instead, focusing on managing the effort rather than pushing hard.<\/p>\n<h2 id=\"listen-adapt-accept\" class=\"ai-optimize-26\">Listen, Adapt, Accept<\/h2>\n<p class=\"ai-optimize-27\">That\u2019s the key word here: <strong>accept<\/strong>. Is the heat slowing you down? Good. That\u2019s normal. Your body is speaking to you. You can choose to listen and still have a valuable training session, or you can stubbornly fight it\u2014and risk ending up wiped out (or worse, sick).<\/p>\n<p class=\"ai-optimize-28\">Personally, every summer I find myself relearning this dialogue. My pace drops, my heart rate rises, sweat becomes my constant running companion. But there\u2019s something beautiful in all of this: learning to understand yourself, to take care of yourself, to realize that progress isn\u2019t only measured by the numbers on your watch.<\/p>\n<p class=\"ai-optimize-29\">So next time you head out for a run and the heat feels like an invisible wall, remember: it\u2019s not you slowing down. <strong>It\u2019s your body working *for* you, not against you<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>How heat affects your running pace and why it\u2019s normal to slow down in summer.
