The Amount of Water You Actually Need Per Day

A professor from the University of Connecticut explained that how much water one should drink each day really depends on the person.

"Fluid needs are dynamic and need to be individualized from person to person. Factors such as sex, environmental conditions, level of heat acclimatization, exercise or work intensity, age, and even diet need to be considered," Robert A. Huggins, Ph.D., said.

He added that simply listening to your thirst is the best way to gauge when to drink. Another approach to monitor hydration is to look at your pee before you flush, Time informed. You want it to look like lemonade; if it's darker than that, you should down a glass.

Dr. Robert also gave some tips on how to gauge water one specifically should take in during exercise.

First, you should weigh yourself wearing with little to no clothing before you workout. "If you can, [make sure you're hydrated beforehand] and avoid drinking while you exercise to make the math easy," he said. However, he said now to ignore if you feel thirsty: drink some and make sure to measure the amount.

Next, weigh yourself again after you're done exercising. Then, get your sweat rate by taking your first weight and subtracting the second weight. Convert it into kilograms, then drink that amount in liters. Moreover, you need to subtract the amount of water you drank during exercise from your final total.

Water is the principal chemical component of the human body as it makes up about 60 percent of our body weight, Mayoclinic informed. In fact, every system on the body depends on water.

Moreover, it should be noted that over-hydrating may actually be as bad as dehydration.

A report in the British Journal of Sports Medicine revealed that several athletes are at risk of exercise-associated hyponatremia, an electrolyte imbalance which is caused by drinking too much liquid that could lead to nausea, vomiting, headaches, fatigue and, in serious cases, coma and even death.

The Crossfit, Inc-funded research concluded that countless athletes are actually dangerously over-drinking during events as 10k races and even bikram yoga classes despite the fact that it was formerly assumed to only be a concern for long-distance athletes competing in events like Ironmans and marathons, Tamara Hew-Butler, Ph.D., lead author of the paper said to Health. Because "it is impossible to recommend a generalized range especially during exercise when conditions are dynamic and changing, there is not one size that fits all!" she added.
