How Much Water Should Women Over 40 Be Drinking? A Guide to Staying Hydrated and Healthy
As we get older, our bodies change—and so do our nutritional needs. One of the most often overlooked aspects of a healthy diet is hydration. For women over 40, staying properly hydrated is especially important to support metabolism, hormone balance, skin health, and joint function. But how much water is enough?
The Basics: General Recommendations
The National Academies of Sciences, Engineering, and Medicine recommends about 2.7 liters (91 ounces) of total water per day for women. This includes all fluids consumed—not just plain water, but also water from food and other beverages like tea or soup.
However, the right amount can vary depending on several factors including:
-
Activity level
-
Climate or environment
-
Health status and medications
-
Diet (e.g., high-protein or high-fiber diets require more water)
Why Hydration Matters More After 40
At this stage of life, the body starts producing less estrogen, which can lead to a decrease in skin elasticity, slower metabolism, and joint stiffness. Drinking enough water can help:
-
Maintain skin moisture and elasticity
-
Support kidney and digestive function
-
Regulate appetite and metabolism
-
Reduce joint discomfort and inflammation
-
Prevent urinary tract infections, which become more common with age
Signs You're Not Drinking Enough
You might not be as thirsty as you used to be—thirst perception can decline with age—so it's important to recognize other signs of dehydration:
-
Fatigue or low energy
-
Headaches
-
Constipation
-
Dry skin or lips
-
Dark-colored urine
-
Dizziness or confusion
Tips for Staying Hydrated Without Overthinking It
-
Start your day with a glass of water before coffee or tea.
-
Keep a water bottle with you at all times—you’re more likely to sip when it’s convenient.
-
Infuse your water with lemon, cucumber, or berries for flavor.
-
Eat water-rich foods like cucumbers, watermelon, lettuce, and oranges.
-
Limit dehydrating drinks like alcohol or too much caffeine, which can contribute to fluid loss.
When to Drink More
-
During or after exercise
-
In hot or humid weather
-
When you're ill or recovering from illness
-
If you're taking medications that have a diuretic effect
-
If your diet is high in protein, fiber, or salt
Final Thoughts
For women over 40, hydration isn’t just about quenching thirst—it’s a crucial part of aging well. Aim for about 8–10 cups of water daily, adjust for your activity level and health needs, and listen to your body’s signals. Your skin, joints, and energy levels will thank you.
