2. Dizziness and Fainting

Heat stroke can cause dizziness or a spinning sensation, sometimes with blurred vision or ringing in the ears. In more serious cases, the person may faint. Anyone feeling dizzy in the heat should sit or lie down right away in a cool, shaded place to avoid injury from a fall. Moving out of the heat is the priority. If the person is fully alert and able to swallow, small sips of cool water can help, but don't give fluids to someone who is confused, drowsy, or losing consciousness, as it can cause choking.
