Water intake per day

The National Academies of Science, Engineering, and Medicine of the United States determined that an adequate daily intake of fluid is:

Women: 2.7 liters (11.5 cups)
Men: 3.7 liters in weight (15.5 cups)

Water ingested by liquids and food is included in the proportions outlined above. Around 20 percent of the daily fluid intake is derived from food in the majority of cases, and the rest comes from drinks.

Water intake in winter

The truth is that in winters, too, it is highly necessary for us to keep ourselves well hydrated during the year. A male requires 120 ounces of water on average and a female needs about 91 ounces of water, both from food and drink.

Water Intake During Breastfeeding or maternity.

You will need to drink additional water whether you are pregnant or breastfeeding, to ensure that you stay properly hydrated.

Water intake for weight loss

Often, consuming too much water is not recommended either, since it can cause water toxicity. In severe situations, such as during water drinking competitions, this has also induced death. Bottom line: 1-2 liters of water per day is adequate to help with weight loss, especially when ingested before meals, according to the studies.

Water intake according to BMI

Know your weight: Learning your weight is the first step to knowing how much water to drink every day. The amount of water that a person can drink depends depending on their weight, which makes sense because the more water they choose to drink, the more someone weights. Every day, a two-hundred-pound man and a 100-pound woman need varying quantities of water.

Then multiply by 2/3: Next, to decide how much water to drink each day, you want to multiply your weight by 2/3 (or 67 percent). If you weighed 175 pounds, for example, you can multiply it by 2/3 and discover that every day you can drink about 117 ounces of water.

Your Height: According to BMI water intake is calculated by measuring the body mass index and then accordingly required water is calculated for keeping the body hydrated. For this you must know your height to put into formula given above.

Season: Obviously season matters a lot when we talk about drinking water. Our body needs plenty of water during summer season due to sweating while less in winter as compared to summer. But it doesn’t mean water is less important in winter. We needs sufficient amount of water to keep hydrated in winter as well.

Your activity level: Finally, because you’re expelling water while you sweat, you’ll want to change the amount depending on how much you work out. For each 30 minutes that you work out, you can add 12 ounces of water to your daily count. So if you work out every day for 45 minutes, add 18 ounces of water to your daily consumption.


1- Human body consists of 60 – 70% water.

So by assuming this proportion in mind we must drink 60 – 70% water with our foods whatever we eat in daily routine.

2- Beverages like coffee, tea and alcohol all are dehydrating that means they all eliminate water from our body.

So if you take any of these, you must drink extra water to avoid dehydration.

3- Drink a glass of water before every meal. Because it would protect you from harmful concentrated acid in stomach (make dilution) and also keep you in a healthy weight.
