Water is one of the simplest, most powerful tools for your health — and it costs almost nothing. Staying hydrated supports nearly every bodily function, yet knowing exactly how much you need and what counts toward your daily intake can still feel surprisingly murky.
As Yahoo Health reports, your body loses water constantly through sweat, urine, and even breathing. Since roughly 60% of your body is made of water, keeping those levels balanced is essential for feeling and functioning your best.
“Hydration supports every single cell in our bodies, and its functions range from large-scale processes, like removing waste, to smaller processes, like regulating our temperature. Every aspect of our health relies on hydration as a core pillar for success,” says Emily Hulse, registered dietitian and owner of Emily Grace Nutrition.
You’ve probably heard the “eight 8-ounce glasses a day” rule, but hydration isn’t one-size-fits-all. Men generally need more than women, and athletes or anyone active in hot, dry conditions face a higher risk of dehydration. So, here’s everything you need to know — from how much to drink to spotting dehydration and hitting your daily goals.
How much water should you drink a day?
Let’s get right to it. For the average healthy adult living in a temperate climate, the United States National Academies of Sciences, Engineering, and Medicine estimates the ideal daily fluid intake to be:
- 11.5 cups of water (2.7 liters or 92 ounces) a day for women
- 15.5 cups of water (3.7 liters or 124) a day for men
Keep in mind that actual water needs vary depending on multiple factors, including:
- Age
- Body weight and composition
- Humidity
- Weather conditions
- Elevation
- Activity level
- Health status
- Diet
Also, these recommendations were specifically created for sedentary individuals — so on days when someone isn’t exercising or otherwise participating in physical activity. This means your needs will automatically increase if you’re regularly active.
When more water is needed
As lovely as it would be to have a consistent water goal each day, there are several instances when your body needs more than the recommended 11.5 or 15.5 cups.
Hydration needs typically increase in the following circumstances:
- When living or exercising at high elevations
- In hot, humid or dry environments
- During the summer months
- During and after exercise, especially after high-intensity and endurance workouts
- After drinking caffeinated beverages
- After eating salty foods
- When you’re sick
- While taking certain medications, such as diuretics or ACE inhibitors
- While pregnant and breastfeeding
Hydration needs can also be higher if you have a chronic health condition, such as type 2 diabetes.
How can you tell if you’re drinking enough water?
One of the best ways to tell whether you’re getting enough H2O is by checking your urine color. “A clearish yellow to light yellow shows adequate hydration, while a darker yellow to brown shows minimal to severe dehydration,” explains Jessica M. Kelly, registered dietitian and owner of Nutrition That Heals.
Additional symptoms of dehydration include:
- Fatigue
- Increased thirst
- Dry skin
- Chapped lips
- Headaches
- Muscle cramps
- Lightheadedness
- Elevated heart rate
If you’re particularly concerned about your hydration status, chatting with your primary care physician is a good idea. The doctor can order blood or urine testing to objectively determine whether your body is getting the water it needs.
How to stay hydrated throughout the day
Maintaining adequate hydration is essential for overall health, but if you find it a struggle to consume enough water, these practical strategies can help:
- Buy a large water bottle: It might sound obvious, but buying a water bottle is one of the best ways to stay hydrated since you can carry it with you everywhere. To avoid multiple trips to the fridge, I recommend purchasing a 1- or 2-liter bottle or tumbler. While hydration needs vary, if you fill up your large water bottle twice — and drink it all! — you should be at, or close to meeting, your daily water goal.
- Set a timer: “If you forget or get too busy to drink water, keep yourself accountable by setting a timer on your phone. Many of us get involved in work, running errands and taking care of little ones. As a result, we might put taking care of our health on the back burner. Set yourself up for success by proactively setting an alarm and drinking water when it goes off,” recommends Hulse.
- Invest in a tracker: For the more tech-savvy, consider downloading a tracking app to monitor your water intake or splurge on a wearable device with a water-tracking feature.
- Make it part of your morning: According to Kelly, a great way to stay hydrated is by making water a key part of your daily routine, including the morning. Rather than reaching for coffee first thing after waking up, challenge yourself to down at least one glass of water before getting your caffeine fix.
- Change the flavor: Let’s be honest — water isn’t the most exciting beverage in the fridge. If your taste buds could use a little excitement, consider infusing your water with cucumber, strawberries, mint, or other natural flavor boosters. And by the way, flavored water and sparkling water is just as hydrating a regular water. Even flavoring it with herbal (non-caffeinated) tea is a go-to hydration helper for many experts.
- Gameify it: Our brains are motivated by challenges. If you’re struggling to drink enough water, consider setting specific goals. For example, see if you can drink four glasses of water by lunchtime or reward yourself with a fun mocktail after meeting your water goal three days in a row.
