Drink plenty of water and don't wait until you are thirsty to drink. Avoid alcohol or liquids containing large amounts of sugar. Wear and reapply sunscreen as indicated on the package. Ask if tasks. Can be scheduled for earlier or later in the day to avoid midday heat. Wear a brimmed hat. And loose., lightweight, light-colored clothing. Spend time in air-conditioned buildings.
