10 Heat Exhaustion Symptoms
Symptom #9: Rapid Heartbeat
Having a rapid heartbeat can be an indication of heat exhaustion. If you’re exercising, it can be hard to determine whether or not you have heat stroke from your heartbeat alone because it will already be beating faster than normal.
However, if you’re sitting at rest and find your heart beating quickly in addition to some of these other symptoms, it’s probably time to cool down.
