• Upset stomach or vomiting
• Pale complexion, clammy or moist skin, heavy sweating

Safety Tips

• Avoid heavy exercise or work in the heat unless you are used to it.
• Drink plenty of liquids, especially water. Don't wait until you're thirsty to start drinking.
• Avoid alcohol, caffeinated drinks or heavy meals.
• Wear lightweight, light-colored, loose-fitting clothes.
• Take frequent breaks, especially if you notice you're getting a headache, cramps or start to feel overheated.
• Stay out of the sun as much as possible. Try to stay in a cool, shaded area.
• Wear a hat or cap.
• Use cooling fans.
• Rest regularly.
• Watch for signs and symptoms of heat-related illnesses.
