Exertional heat illness occurs when your body overheats during exercise. As your condition gets worse, your body can lose its ability to regulate temperature and lead to heat stroke when your temperature is above 105°F (40.5°C). It’s also important to seek prompt medical attention if you experience extreme fatigue, dehydration, dizziness, or difficulty breathing during exercise.
