Calculating Optimal Daily Water Intake
Gender
Gender plays a significant role in how much water you need to consume on a daily basis.
In general, men need to consume roughly 33% more water than women each day.
Age
Another factor that can influence how much water you need to drink is age.
Our water calculator takes age into age and gives you a rough estimate of how much you need to drink based on your age.
Weight
Calculating your water intake by weight is essential if you want to get an accurate reading.
The more you weigh and the higher your body mass/body fat, the more water you will need to consume.
Height
Height is another important factor that can influence how much you need to drink.
In general, taller people need to drink more water than shorter people.
Season
Season can make a massive difference in how much water you consume.
The summer months often require us to drink much more water due to excessive sweating.

- The amount of water each person needs can vary based on factors such as age, sex, weight, activity level, and climate.
- The general recommendation for adults is to drink at least 8-10 cups (64-80 ounces) of water per day, but this can vary depending on individual needs.
- Approximately 20% of our daily water intake comes from food, while the remaining 80% comes from beverages.
- Even mild dehydration can negatively impact physical and cognitive performance, including mood, concentration, and alertness.
- Thirst is the body’s way of signalling that it needs more water, so it’s important to drink water when you feel thirsty.
- Drinking water before meals can help to promote weight loss by reducing appetite and increasing feelings of fullness.
- Athletes and people engaging in strenuous physical activity may need to drink more water to compensate for fluid loss through sweat.
- Drinking water can help to prevent and treat headaches, as dehydration is a common cause of headaches.

Sources Of Water In The Human Body
Drinking water and other beverages: The water we drink, including tap water, bottled water, glasses of water, plain water, and other beverages like tea, coffee, and juice, provide a significant source of water in the body.
Food: Many foods also contain water, such as fruits and vegetables like watermelon, strawberries, oranges, cucumbers, lettuce, and tomatoes.
Foods with high water content can help to keep the body hydrated.
Metabolic water: The body also produces water through metabolic processes, as a byproduct of the breakdown of carbohydrates, proteins, and fats.
Body fluids: Body fluids such as blood, lymph, and urine, also contain water. Saliva and digestive juices: Saliva and digestive juices also contain water and play a role in breaking down food and absorbing nutrients.
Why Do We Need To Drink So Frequently?
We need to drink water so frequently because it plays a critical role in many functions in the body such as regulating body temperature, transporting nutrients and oxygen to cells, and removing waste products from the body.
Water is also constantly being lost through sweating, urination, and breathing, so we need to replenish the lost fluids by drinking water and other hydrating fluids.
General Water Drinking Recommendations
While the amount of water you have to drink will be dependent on several factors such as age, height, and weight, there are a few general recommendations that you could follow if you feel like our water intake calculator is off the mark.
For most men, you should drink roughly 4 litres of water per day.
For women, the amount is reduced to 2.7 litres per day.
These guidelines are based on averages, so do not assume that these amounts will be ideal for you.
However, they can give you a rough idea.
Adjustments For Climate, Excessive Sweating & Pregnancy
It is worth knowing that you may need to make adjustments to the estimation that our water intake calculator gave you depending on your circumstances.
For example, if you live in a hot climate, have a condition that makes you excessively squat or are pregnant, then you may need to up your water intake to compensate.
These are but a few of the many examples that could require you to drink more water, and it is important to understand that our water intake calculator is not always correct.

Water is zero calories and can make you feel full without eating any additional food, and this makes drinking more water great for weight loss.
It might not help in the way you think, but it certainly can help.
