Offer liquids throughout the day; don’t wait for the person to ask.
Don’t just hand over a glass; stand by and make sure the drink is actually sipped.
Vary the types of beverages offered: water, juice, milk, hot chocolate, cider. Even coffee, tea, and soda are okay in moderation (about a cup a day) if the person prefers them.
Do, however, curb caffeinated beverages if fear of getting to the bathroom on time is an issue, as caffeinated drinks can cause frequent urination.
Issue mild reminders during the meal: “Have a sip of water…try the iced tea”.
Leave athletic water bottles around the house or carry them around during the day.
Serve fruit, which contains a lot of water, especially watermelon, melon, and citrus.
Be sure you know the symptoms of dehydration: increased confusion or lethargy, complaints of headache, dry skin or mouth, feeling warm to the touch.
Know that diarrhea and vomiting increase the risk of dehydration, so monitor the person especially closely when he’s ill, and notify the doctor if you suspect dehydration.
