We've all heard it — from our moms, coaches, doctors, and more: "Stay hydrated." While many people believe they need to drink eight glasses of water per day, that's one of many common misconceptions about what staying hydrated really means.
Water is essential for regulating body temperature, supporting joint lubrication, and maintaining organ function. But your hydration needs vary all the time. Factors like age, health, and climate influence how much water your body needs.
Separating facts about hydration from the myths can be a tricky task. But knowing the right facts about drinking water and the difference between hydration vs. dehydration can help you set better hydration goals.
Let's debunk some common myths about dehydration, explore the facts, and find the best way to hydrate.
Myth 1: You Need To Drink 8 Glasses of Water a Day
Among all common water drinking “facts,” the notion that you must drink eight glasses of water daily is a myth. Hydration needs vary widely among individuals. Mayo Clinic recommends a daily intake of about 125 ounces, or 3.7 liters, for men and 91 ounces, or 2.7 liters, for women. This is approximately 15 cups of water for men and 11 cups for women.
Several other factors affect your hydration needs:
- Age: As you age, you may need more hydration due to changes in body composition and kidney function. The National Council on Aging recommends that older adults should drink about one-third of their body weight in ounces of fluids daily, including water from all sources.
- Body size and weight: Your body size and weight affect your hydration needs. If you have a larger build, you'll need more fluids to maintain hydration levels.
- Physical activity levels: Activity levels affect hydration, as you'll need more fluid intake to compensate for water loss through sweat.
- Diet: If your diet includes water-rich foods and beverages, you may not need to drink as much water.
- Health status: Medical conditions like diabetes or kidney disease can impact your hydration needs.
- Medications: Medicines like antidepressants and diuretics increase urine production. If you're taking them, you may need to increase your water intake to maintain your hydration balance.
- Climate: The climate also influences hydration needs — if you live in a hot, humid environment or you're in the heat of summer, you'll need more fluids.
Myth 2: Thirst Is the First Sign of Dehydration
Contrary to popular belief, thirst doesn't always indicate dehydration. Conditions like diabetes or medication side effects can trigger thirst even if your body isn't dehydrated. Eating spicy foods can also increase thirst levels.
Sometimes, you may feel not thirsty but are dehydrated because of age-related changes, medications like antidepressants, or cold, moist environments.
Understand your body's signals, and drink water when you're thirsty. But know that thirst alone doesn't necessarily mean you're dehydrated.
Myth 3: Coffee and Tea Cause Dehydration
If you're a tea or coffee drinker, you might have heard that these beverages can cause dehydration. However, this common belief doesn't match research findings.
Coffee and tea contain caffeine, which is a mild diuretic that removes water from your body through urine. But these beverages include water. So, the overall fluid content offsets potential dehydration.
Moderate consumption of these beverages can contribute to your daily hydration needs. You can safely consume up to 400 mg of caffeine per day, which is 4 cups of coffee or 8 cups of black tea.
However, the hydration benefits of coffee and tea can vary depending on your caffeine tolerance and dietary habits. So don't replace your daily glasses of water with these beverages.
Myth 4: Clear Urine Means You're Well-Hydrated
Pale yellow urine may suggest healthy hydration, but clear urine may not always indicate the same. If you notice clear urine often, you may have overhydration, where the body retains excessive water.
Overhydration occurs when your body retains more water than it can excrete. This can happen because of excessive water drinking to prevent dehydration. Medical conditions, like heart problems and kidney failure, can also be the cause. It’s common in athletes who drink too much water after prolonged endurance exercises without electrolyte replacement.
The symptoms of overhydration include nausea, headache, confusion, and in severe cases, seizures or coma. To avoid overhydration, monitor fluid intake and recognize these symptoms.
Instead of relying solely on urine color to measure hydration, consider all the factors that can affect your hydration levels.
Myth 5: Only Athletes Need To Worry About Electrolytes
Dehydration affects your body's electrolyte balance. Electrolytes are minerals, such as sodium, potassium, and magnesium, that maintain proper hydration, nerve function, and muscle health. They are essential for your body — and they're not just for athletes.
Athletes may have higher electrolyte needs due to sweat loss during intense exercise. However, everyday activities and health conditions can also affect your electrolyte balance.
Everyone, whether a high-powered athlete or not, should try to maintain adequate electrolyte intake through food and beverages for balanced hydration.
Myth 6: Dehydration Isn't a Serious Health Issue
Proper hydration is important for maintaining your body functions like temperature regulation and nutrient transport. Dehydration really can lead to serious health concerns.
In mild cases, such as dehydration due to heat or exercise, immediate rehydration with electrolyte replacement can balance things back out. However, if you face prolonged or severe dehydration, you may need to seek immediate medical attention to prevent health consequences.
Dehydration can lead to these symptoms:
- Dry mouth
- Fatigue
- Headache
- Dizziness
- Confusion
- Dark-colored urine
- Extreme thirst
Severe cases may lead to kidney stones, urinary tract infections, and even heat-related illnesses like heat exhaustion or heat stroke.
Recognize these signs of dehydration, and take steps to prevent it and maintain your hydration balance.
Myth 7: You Can Only Stay Hydrated by Drinking Water
Drinking some water throughout the day is beneficial, but it's not the only source of hydration your body needs. Approximately 20% of your daily fluid intake comes from foods with high water content. This could include foods like cucumbers, celery, strawberries, grapefruit, spinach, and watermelon.
Soups, broths, and stews in your diet also help maintain hydration, especially during colder months. To improve hydration, opt for low-sodium options. High-sodium foods like packaged snacks can lead to dehydration by promoting water loss from cells. The Food and Drug Administration recommends limiting daily sodium intake to 2,300 milligrams to prevent dehydration and maintain overall health.
