To my Israeli readers and anyone else in extremely hot weather: Drink pure water! Aim to down about 3 liters minimum in a day - in addition to natural fruit juices and teas.
If you or someone else looks pale, slows their speech and body movements and/or seems confused in the heat, call a doctor immediately.
Be sure to read Signs and Symptoms of Dehydration.
