Water alone won’t cut it, experts share smart tips to stay truly hydrated all day

As temperatures rise across the United States, simply drinking water will not be sufficient to keep you hydrated. Nutrition experts are urging people to reconsider how they hydrate, because heat, sweating, diet, and even alcohol can all disrupt your hydration.

Experts say that true hydration necessitates a balance of water, electrolytes, and food. With 2025 shaping up to be one of the hottest years on record, understanding dehydration symptoms, smart snacking, and hydration timing can help you stay safe, alert, and refreshed throughout the summer.

People who drink a lot of water may experience dehydration, also known as hyponatremia, which is characterized by low blood sodium levels. Long-distance runners and other athletes may also be affected because they lose a lot of electrolytes through perspiration and then consume a lot of water, which further dilutes sodium levels.

What are the real signs of dehydration?

Lightheadedness, dizziness, moodiness, irritability, exhaustion, lack of appetite, and cramping in the legs or stomach are all signs of dehydration.

Hyponatremia, or overhydration, is the result of having too little sodium in your blood. People who drink a lot of water may experience it because it dilutes the sodium in their blood.

Experts share these smart tips to stay truly hydrated all day:

Consume foods that hydrate you

Consuming hydrating foods is crucial for adequate hydration, with fruits and vegetables being particularly effective due to their water and electrolyte content. Watermelon, peaches, apples, berries, lettuce, tomatoes, and carrots are highly hydrated and include electrolytes such as potassium and magnesium.

Don't drink alcohol

Refraining from alcohol is essential for preserving hydrated. Frozen beverages such as strawberry daiquiris may appear to alleviate thirst; nevertheless, they actually exacerbate dehydration and disrupt electrolyte balance. With the availability of zero-proof beverages, consider indulging in a non-alcoholic mocktail, which remains enjoyable in warm weather.

Know how electrolytes operate and maintain a regular diet

Comprehending the function of electrolytes is crucial for maintaining hydration in elevated temperatures. The primary electrolytes in the body include sodium, potassium, magnesium, calcium, and chloride. They are essential for various physiological activities, including fluid equilibrium, and are depleted by perspiration, diarrhea, and emesis. Electrolytes are obtained from our dietary intake, and supplementation is only required when electrolyte loss exceeds dietary replenishment.

Throughout the day, drink water more frequently

To prevent dehydration, it is advisable to consume water consistently throughout the day and utilize alarms or hydration applications as reminders to maintain adequate hydration. A consistent eating schedule is crucial, as abstaining from food might exacerbate the condition. Select lighter, low-fat foods that facilitate digestion, while fried foods are more challenging to digest and need significantly more energy from the body.

FAQs

Is drinking lots of water enough to keep you hydrated?
Not always. You also need electrolytes, especially if you're sweating heavily. Water alone can dilute sodium levels, resulting in cramps and fatigue.

Which foods help with hydration?
Water-rich fruits and vegetables like watermelon, cucumbers, berries, and lettuce are ideal. They not only hydrate, but also replenish lost electrolytes such as potassium and magnesium.
