Always listen to your body and stop exercising in the heat if you feel any nausea or dizziness or have pale or cold skin with goosebumps. These are all possible signs of heat exhaustion, according to the Mayo Clinic.

Signs of dehydration include headache, confusion, fatigue, lightheadedness, chills and dark-colored urine, according to the Cleveland Clinic. Stop exercising and hydrate if you experience these symptoms.
