How do I prevent a dehydration headache?

The best way to avoid a dehydration headache is to stay hydrated. To prevent dehydration, you should:

• Drink plenty of fluids: Carry water with you when you leave home, and take sips throughout the day.
• Hydrate before you feel thirsty: Drink fluids throughout the day. Don’t wait until you feel thirsty. If you wait until you’re craving water, you’re already a little dehydrated. People who are older might not feel thirsty at all because you can lose your sense of thirst as you age.
• Replace the fluids you lose: When you’re exercising or doing physical activity, take water breaks often. During some sports (like swimming), you may not notice how much you’re sweating. Drinking fluid throughout the day prior to participating in a sport is also helpful.
• Take a break when you need to rest: Listen to your body. If you feel tired or dizzy, take a water break.
• Watch the heat: If you’re outside on a hot day, drink extra water. Rest often, and find a way to stay cool in hot weather.
