Enough quantity of how much is required is a subjective term. There’s no standardized amount of water required by the body and for everybody. However, there’s is an estimated amount that scientists believe is clinically required. The following water intake recommendations from the National Academy of Medicine (NAM) in the United States is clinically recommended: 2,700 mL/day (11 cups approx.) for adult women and 3,700 mL/day (15 cups approx.) for adult men.
Just as dehydration is dangerous to the body, so is over-hydration-drinking too much water. Often, we don’t consult medical practitioners for daily water recommendations, but this will be a good practice if you have a fever, diarrhea or if you are vomiting – As water intake usually increase in these scenarios.
Some people require more water, others require less. Individuals’ requirements depend on so many factors. These factors include age, sex, body size, activity level, temperature, health status and exposure to humidity and sun.
In a sunny or humid day, do remember to take extra bottles of water. Humans tend to lose more water in these weather conditions. Expect to drink more than usual with physical or rigorous exercise. The rate at which water is lost through perspiration is much more under intensive exercise.
If you are not sure about your hydration level, check the color of your urine. According to Center for Disease Control (CDC), if your urine is clear, you are in good shape. If not, you might need to be rehydrated.
