Low Blood Pressure
Low blood pressure, which is also known as hypotension. In most cases, having a low blood pressure isn’t necessarily a problem (less than 120/80), however, a low blood pressure can cause dizziness and tiredness. Other symptoms include fatigue, blurry vision, lightheadedness, loss of consciousness, nausea and clammy skin. A sudden and drastic drop in a person’s blood pressure is another symptom of heat exhaustion.
