The Water Formula – How Much Water Should you be Drinking?
If you’re not sure you’re drinking enough water, this blog will give you a formula to calculate how much water is ideal for you.
There is no clear-cut answer as to how much water to drink per day, because it depends upon a number of factors like your health condition, your activity status, the climatic conditions, physical size, your weight and your environment etc.
You lose quite a lot of water through sweating, exhaling and urinating. In hot weather, you tend to lose more water through sweating, in cold condition, you tend to urinate more. In the event of sickness like flu and diarrhoea, you tend to lose fluid. When you weigh more, your body needs more fluid for the muscle, organ, bone etc.
There are many recommendations advise that you drink 8 glasses (250ml/8 ounce per glass = total of approx 2 litre) of water a day.
Is drinking 8 glasses of water enough?
Remove the environmental, climatic factors and your activity level out of the equation, the amount of water intake varies according to your weight. A more accurate estimation is to drink at least half your body weight (in pounds) in ounces of water. Let’s illustrate with the following example:
The Water Formula
You weigh 160 pounds.
160 ÷ 2 = 80 (amount of water to drink in ounce per day)
Answer: Drink 80 ounce of water per day.
(If you divide this further by 8 you will calculate the number of glasses per day.)
80 ounces ÷ 8 = 10 glasses / day
If you are using kilograms, divide the kilograms by 30, this gives you the water to drink per day in litres. Let’s illustrate with the following example:
You weigh 75kg
75 ÷ 30 = 2.5 (amount of water to drink in litre per day)
Answer: Drink 2.5 litres of water per day.
Tips for Drinking Water
Spread the water out evenly throughout the day. If the amount of water is 80 ounces, spread the water out by drinking one 10-ounce glass every hour for eight hours, which is about drinking 8 glasses of water per day.
For exercise, drink 1-2 cup of water 30 minutes before exercise. It helps to replenish the fluid loss and fuel the muscle during the exercise.
Since other factors like your activity level and the environment conditions do affect your water intake, another way to know if you’re getting enough water, watch your urine. It should be light yellow colored or clear. If it is dark or strong smelling, it is time to drink more water. Also watch for other signs of dehydration such as fatigue, headaches, and difficulty concentrating. If you are thirsty, you are already dehydrated. So, “drinking 8 glasses of water” is not a fix rule for your daily water intake.
