How much Water 💦 do we Need a Day?

How much Water do we Need a Day?
Water constitutes 55-60% of an average adult body and much more of younger people. 
As we age, the amount of water in our bodies decreases. 
Many scientists see water as one of the important keys to stay younger and live longer. The amount of recommended daily intake of water varies in different references. But don’t wait for the thirst signal to drink water. 

The U.S. National Academies of Sciences, Engineering, and Medicine recommend an average of 11.5 cups (2.7 liters) of total fluids daily for women, and 15.5 cups (3.7 liters) for men. 
This includes all fluids from drinking water, other beverages, and the ~20% of water we get from solid foods.  
 [1, 2, 3, 4]
However, there is no one-size-fits-all number. Your specific daily needs depend heavily on factors like your environment, activity level, and overall health: [1, 2, 3]
  • Exercise: If you sweat through a workout, you should drink an extra 8 ounces for every 30 minutes of activity.
  • Climate: Hot, humid, or high-altitude environments require you to consume more fluids.
  • Health Factors: Pregnant and breastfeeding women generally need 10 to 12 cups daily. Individuals with specific medical conditions or taking certain medications may need more or less. [1, 2, 3, 4, 5]
How to check if you're hydrated:
The easiest way to tell is by looking at the color of your urine -it should be a pale, clear yellow. If you rarely feel thirsty and your urine is pale yellow, you are likely drinking enough. [1, 2]
For a personalized daily fluid target based specifically on your weight, activity level, and local climate, use the Daily Water Intake Calculator. [1]
What type of water is the healthiest?
Plain water is the best choice to stay hydrated and keep your body running smoothly.
There are times when electrolyte water can bolster the electrolytes you get from your diet — think hot temperatures, when you are exercising for a long time or after an illness with vomiting and diarrhea. But often, other types of water and sports beverages are not necessary. They may also contain added sugars which can lead to weight gain.
Mayo Clinic Minute:
How Much Water Should You Drink?

👇  💧  👇

💦💧💦
1. Eight glasses is great... for some people 
While the general Eight Glasses a Day mantra is a good starting point, how much water you really need can depend on a few different factors like
age, weight, health, diet, and geography. "The heavier you are, the more water you probably need. If you live in a hot and humid climate are you need to increase your water intake. If you're a gym rat, you'll need to have more water than someone whose daily exercise is walking from the kitchen to the couch." See what we mean?
💧
2. All glasses aren't created equal 
It's important to note that these eight glasses should be
eight ounces each - those tiny paper cups at the water cooler don't count!
💧
3. Other drinks don't count
While some drinks like teas, juices, and milk will hydrate you, water is still the ideal.
Beverages like coffee, soda, and sugar-heavy 'ades definitely shouldn't count towards water consumption.

Editorial Reviews
Is access to clean drinking water a basic human right, or a commodity that should be bought and sold like any other article of commerce? Stephanie Soechtig's debut feature is an unflinching examination of the big business of bottled water. From the producers of 'Who Killed the Electric Car' and 'I.O.U.S.A.,' this timely documentary is a behind-the-scenes look into the unregulated and unseen world of an industry that aims to privatize and sell back the one resource that ought never to become a commodity: our water. 

From the plastic production to the ocean in which so many of these bottles end up, this inspiring documentary trails the path of the bottled water industry and the communities which were the unwitting chips on the table.
-
The high cost -- to both the environment and our health -- of bottled water is the subject of this documentary that enlists activists, environmentalists, community leaders and others to expose the dark side of the bottled water industry. 
Americans may rethink their obsession with bottled H20 when they learn of the unregulated industry's willingness to ignore environmental and health concerns, and the problems that arise as a result.
