Understanding Skin Temperature

Understanding Skin Temperature and Its Role in Heat Safety

What Is Skin Temperature?
Skin temperature is the temperature measured at the surface of your body. Unlike core body temperature, which reflects the heat of your internal organs, skin temperature is more immediately affected by your surroundings—like air temperature, humidity, sun exposure, and even clothing or equipment.

Why Skin Temperature Matters in Athletics
During exercise, especially in the heat, your body tries to cool itself by directing more blood to the skin and activating sweat glands. Elevated skin temperature can be a sign that your body is struggling to release internal heat effectively. It often rises before core body temperature, acting as an early indicator of heat buildup.

Key Reasons Skin Temperature Is Important

• Early Warning: Changes in skin temperature can indicate that your environment or exertion level is pushing your body toward heat stress.

• Heat Loss Insight: When skin temperature stays high and sweating is ineffective, your body may not be cooling itself properly.

• Environmental Sensitivity: Skin temperature helps measure the impact of turf heat, direct sunlight, or hot equipment on an athlete's body.

Smarter Decisions with Skin Temperature Data
When paired with core body temperature and heart rate, skin temperature gives a more complete picture of an athlete’s thermal state. This helps HeatSense deliver alerts and insights tailored to each individual, keeping you safer during practices and games.
