Staying hydrated is critical for health. Water helps regulate body temperature and can help maintain cognitive function. Despite hydration’s importance, U.S. adults may not be familiar with the common signs of dehydration and how to fix it.

In this article, we’ll address signs of dehydration, provide tips for staying hydrated, and answer your other burning questions about hydration

How to Stay Hydrated and Other Common Questions

How much fluid do I need?

For general daily needs, women and men may need about 9 and 13 cups of fluids per day, respectively. However, exact hydration needs can vary depending on age, activity level, the weather or health status.

What is the best way to hydrate?

Drinking water is one of the best tips for staying hydrated. Foods with high water content such as watermelon, celery, cucumbers and lettuce are also hydrating. However, when you’re dehydrated, water is not always enough. Drinks with electrolytes and glucose (sugar), like Pedialyte, can help replenish fluids and minerals the body loses during exercise, exposure to heat, and some illnesses.

What are the signs of dehydration?

Common signs of mild to moderate dehydration may include:

  • Thirst
  • Dry mouth
  • Fatigue
  • Muscle cramping
  • Dizziness
  • Irritability

Why are electrolytes important for hydration?

Electrolytes like sodium, potassium, and chloride support muscle, nerve, and normal organ function. When you lose fluids through sweat or illness, you also lose electrolytes. Choosing a drink like Pedialyte that replaces both water and electrolytes can help you effectively rehydrate.

I thought sugar was unhealthy – why is it in my electrolyte drink?

In the right amount, sugar (specifically glucose) serves as a vehicle to help your body absorb electrolytes more effectively. Glucose works with sodium to move fluids into your bloodstream,  helping replenish lost sodium and helping your body absorb lost water.

Balance is key. Some beverages have too much sugar, which can slow down hydration. Pedialyte is carefully formulated with an optimal ratio of sugar and electrolytes and has two to three times the electrolytes of the leading sports drink*, helping you rehydrate effectively.

Do coffee and energy drinks count as hydrating fluids?

Yes, coffee and energy drinks can contribute to daily fluid intake in moderation. While caffeine-containing beverages may increase urination, consumption around 300 mg per day are not expected to cause excess fluid loss. Balance caffeinated drinks with water or an electrolyte drink, especially when you're sick, active, or spending time in the heat, for proper hydration.

Don’t let dehydration slow you down

Hydration is powerful yet often overlooked in helping reduce feelings of sluggishness and fatigue, while supporting focus and overall well-being, especially in the heat, during illness, or while on-the-go. While plain water should be a staple in all diets, it’s not always enough when you are dehydrated.

Understanding the signs of dehydration and how to fix it is imperative. Stay on top of your hydration and don’t wait until you’re thirsty to consume fluids. If you’re unsure of how well you are hydrating, speak to your doctor about your hydration status and needs.

Incorporating electrolyte solutions like Pedialyte is a tasty and effective way to replace both fluids and vital minerals lost through sweat or due to vomiting or diarrhea from sickness. With the right mix of water, nutrient-rich foods like fruits and veggies and smart hydration solutions, you can manage your hydration and feel your best no matter what the day brings.
