Hydration means having enough water in your body for it to work well. Water is needed for almost everything your body does-keeping your temperature steady, moving nutrients around, and helping you get rid of waste. Even being a little dehydrated can make you feel different.
If you don’t drink enough, you might feel tired, cranky, or have a headache. For people with ARFID or eating challenges, dehydration can make it even harder to eat well or feel hungry. Drinking enough water helps your body and mind feel better, making it easier to face food challenges.
Try to sip water throughout the day, not just when you’re thirsty. Add a glass of water to each meal or snack. Eat fruits and veggies with lots of water, like watermelon, cucumber, or oranges. If plain water is hard, try adding a splash of juice or a slice of lemon for flavor.
