When temperatures rise, staying hydrated becomes even more important. Learn how smoothies, popsicles, and frozen fruit treats can help kids stay cool, hydrated, and nourished all summer long.
Summer is a season filled with outdoor play, sports, vacations, and family adventures. While children are busy enjoying the sunshine, they can also lose more fluids through sweat and may not always recognize when they need a drink. Staying hydrated helps support normal body temperature regulation, energy levels, concentration, digestion, and overall health. ¹
The good news? Hydration doesn’t only come from a water bottle.
Many fruits and vegetables contain significant amounts of water and can help children meet their fluid needs while also providing important vitamins, minerals, fiber, and antioxidants. Hydrating foods can be especially helpful during hot weather, after physical activity, or when children are recovering from illnesses that make it harder to eat or drink normally. ¹, ²
These three kid-friendly recipes are a fun way to help families stay cool while nourishing growing bodies.
Why hydration matters
Children may be at greater risk for dehydration during hot weather because they are often active outdoors and may not recognize or communicate thirst as readily as adults. ¹ Signs of dehydration may include dry mouth, fatigue, headache, dizziness, dark urine, or decreased urination. ²
Offering fluids regularly throughout the day and including water-rich foods in meals and snacks can help support hydration during the summer months. ¹
Kids in the kitchen: building confidence through cooking
Summer is the perfect time to invite children into the kitchen. Involving children in age-appropriate food preparation activities can help build confidence, develop kitchen skills, and encourage interest in healthy foods. ³
Here are some appropriate ways children can help with these recipes:
Ages 2–4
Wash fruits and vegetables
Add pre-measured ingredients to a blender
Stir ingredients together
Help choose popsicle molds or serving dishes
Ages 5–8
Measure ingredients
Peel bananas
Squeeze citrus fruits
Pour smoothie mixtures into cups or molds
Ages 9+

Assist with recipe preparation and cleanup
Adult supervision is always recommended when using blenders, knives, or other kitchen equipment.
