Understanding Core Body Temperature and Why It Matters

What is Core Body Temperature?
Core body temperature refers to the internal temperature of your body’s vital organs. It is one of the most critical indicators of how your body is handling heat. Unlike surface or skin temperature, which fluctuates with the environment, core temperature reflects the actual heat stress your body is experiencing.

Why It’s Important in Athletics
For athletes, maintaining a safe core body temperature is essential. When your core temperature rises too high—especially during intense physical activity in hot environments—it can lead to heat strain and potentially life-threatening heat illness. This risk is even greater on synthetic turf fields, where surface temperatures can reach up to 200°F under direct sunlight.
