The Ironman World Championship in Kona, Hawaii consistently highlights the significant impact of heat and humidity on human performance. Despite being prepared with your hydration and cooling methods, ALL athletes are at risk for a heat-related illness. As an athlete, it's critical to understand thermoregulation, the impact of heat on the body during exercise, heat related symptoms, risk factors, what to do if you suffer from it and how to reduce your risk. Stay smart, stay hydrated, stay cool and stay aware. Your health depends on it. Thermoregulation Thermoregulation is the maintenance of internal core body temperature by balancing heat generation with heat loss. 98.6 F (37 C) is the accepted norm for human body temperature. Hyperthermia occurs when your body absorbs or generates more heat than it can release. Your body is always adjusting to keep your body in homeostasis. Muscle contractions product heat as a by-product of metabolic processes. Because the body is very inefficien...

Tomorrow is the 2024 Men's Ironman World Championship in Kailua-Kona, Hawaii. The females showed us great resiliency, strength and courage on/by the mountains of Nice, France and tomorrow the men will battle it out on an island. The heat and humidity in Kona is something that you have to feel to understand. The human body can do incredible things - like race for 140.6 miles - but it thrives within a limited range of body temperatures. Muscle contractions keep the body moving but a substantial amount of energy is converted into heat. As a result, the body generates a large amount of heat which significantly raises the body temperature. To help keep the body temperature somewhat stable and to prevent overheating, the body must dissipate heat through sweating, increased blood flow to the skin and increased respiration. For the body to do what it needs to do to help you maintain a stable core temperature, you have a responsibility to keep your body hydrated. And hydration doesn't m...
