Where is Water in the Body?
Water is in every part of the body. However, some organs contain more water than others. The kidneys and brain possess the highest percentage, while bones and teeth have the lowest percentage.
Check the chart below for your body organs with the most and least water in percentage.
|Body Part||Water percentage|

How much water does a human drink in a day?
Although experts recommend drinking 64 ounces (about 2 liters of water) daily, this doesn’t work for most humans.
The amount of water a person drinks daily is subject to factors like age, gender, environment, health, and exercise.
You’ll require more water during warm months than in cooler ones because of perspiration. You’ll also take more water if you spend more time outdoors or in a heated room.
Additionally, if you spend much time in the gym daily, you’ll have to drink more water to cover fluid loss. Also, if you are suffering from fever, diarrhea, and vomiting, you’ll need more water. Health conditions like diabetes require you to take more water as well.
Generally, women should take about 11.5 cups of water (2.7 liters) a day; if pregnant or breastfeeding, they need to take additional fluids. Men, on the other hand, should take 15.5 cups or 3.7 liters daily.
Like adults, the amount of water a kid takes daily depends on age, weight, overall health, how active they are, and gender, among others.
Kids and teens should drink 6 to 8 cups of water a day. They also need to eat lots of fresh veggies and fruits.
How much does an average person drink in a month?
In a day, an average person drinks about 3 liters.
In a month, they drink 30 x 3 = 90 liters
An average person drinks about 90 liters of water in a month.
How Much Water Does a Human Drink in a Lifetime?
An average person requires 2.7 to 3.0 liters of water a day. If they were to live for 80 years (a healthy/fit person’s life span is assumed to be 80 years), their lifetime water consumption would be 80 x 365 x 3 = 87600 liters.
That’s a lot of water. In fact, this equals the volume of a 210 cm deep, 7 m long, and 6 meters wide pool.
It’s therefore assumed that a human drinks about 87600 liters of water in a lifetime.
How much water does a person drink during his entire lifetime in liters or gallons?
A fit person’s life span is assumed to be 80 years. They are expected to drink about 3 liters a day in a day. This means that they’ll drink 80 x 365 x 3 = 87600 liters of water in a lifespan.
A healthy person takes, on average, 1 gallon of water per day. If their life span is 80 years, they’ll drink 80 x 365 x1 = 29,200 gallons of water.
Is it okay to drink a gallon of water a day?
If you are healthy, drinking a gallon of water daily is not harmful. However, if suffering from end-stage kidney disease or congestive heart failure, a gallon a day might not work for you as your body won’t be able to process all the water.
Another risk of drinking a gallon of water daily is water intoxication, which can lead to increased pressure in the brain. Failure to seek treatment can lead to seizures and, in extreme cases, coma.
Frequently Asked Questions
Q. Why do I pee so much when I drink water?
The body is good at maintaining proper water balance. The water you drink will therefore match the amount you put out in your urine. That is why the more water you drink, the more you’ll pee.
Q. How long does it take to pee after you drink water?
If well-hydrated and your bladder is close to full or full, it can take you 5 to 15 minutes to pee after drinking water. However, if you have an empty bladder and are dehydrated, it can take as long as 8 to 10 hours before you pee.
Q. How long can you live without water?
You can only survive for up to 3 days without water. Certain factors like the amount of water your body requires and how it uses it can affect this.
Q. Who drinks the most water?
Men drink the most water per day – 3.7 liters a day. They need to drink more water than women because they weigh more.
Q. Does drinking water clear skin?
Yes, drinking water helps clear skin. If you drink enough water daily, you’ll have an excellent balance of water and oil on the surface of your skin. This will help decrease acne breakouts and reduce pore size and blemishes.
Q. How many gallons of water are on earth?
There’s a lot of water on earth. More than 362 million trillion gallons of water. And guess what, less than 3% of this water is fresh water.
Q. How much water do we consume in our lifetime?
We consume about 87600 liters (29,200 gallons) in our lifetime if we live for 80 years.
Q. How much water does a human drink in a year?
Assuming that you drink about 2.5 to 3 liters of water per day, you’ll drink 365 x 3 = 1095 liters of water in a year.
How much water does an average person use (drink + other stuff) during his/her lifetime?
In a day, an average person uses;
- 20 gallons for a 20 minutes shower
- 36 gallons for a full bath
- 19 to 24 gallons for toilet flush
- 15 gallons washing machine load
- 4 to 10 gallons for dishwashing
- 1 gallon for drinking
- 3 gallons for hygiene
This makes a total of 109 gallons per day.
Assuming that an average person’s life span is 80 years:
In a lifetime, they use 80 x 365 x 109 = 3,182,800 gallons. And drink 80 x 365 x 1 = 29,200 gallons
Therefore, in a lifetime, an average person uses 3,182,800 + 29,200 = 3,212,000 gallons.
