Pourquoi l'homme est l'animal le plus endurant face à la chaleur

In June 2026, France experienced a historic heatwave: June 24th, the hottest day ever recorded; June 25th, 72 departments on red alert. We all curse the heat. But your body is one of the most formidable heat-survival machines nature has ever produced. In this video, we go back a million years to understand why you sweat—and why this detail that bothers you might be the secret that saved our species. Bare skin, millions of sweat glands, hunting to exhaustion under the savanna sun… and a Kalahari hunter, filmed, taking down a greater kudu on foot. Your marathon-running body has come a very, very long way. 📚 Main sources: Endurance hypothesis (Bramble & Lieberman, Nature 2004); documented San hunts (Kalahari); eccrine thermoregulation physiology; June 2026 heatwave report (Météo-France). ⚠️ This video presents the endurance hypothesis, which is supported by numerous indicators but remains debated. This is not medical advice: in extreme heat, stay hydrated and protect yourself. #prehistory #evolution #heatwave
