Water is essential for human survival. An adult body is made up of about 60 percent water, and a newborn is made up of 74 percent of water. Water removes waste from cells, brings nutrients to cells, regulates body temperature and helps you digest food. When you don’t consume enough water, serious complications can arise. Your hydration needs depend on exercise, diet, age, body fat, altitude, pregnancy, medications and the weather.
Here is how to calculate, how much water you should drink a day for both health and weight loss benefits.
Your weight: The first step to knowing how much water to drink everyday is to know your weight. The amount of water a person should drink varies on their weight, which makes sense because the more someone weighs the more water they need to drink. A two hundred pound man and 100 pound woman require different amounts of water every day.
Multiply by 2/3: Next you want to multiple your weight by 2/3 (or 67%) to determine how much water to drink daily. For example, if you weighed 175 pounds you would multiple that by 2/3 and learn you should be drinking about 117 ounces of water every day.
Activity Level: Finally you will want to adjust that number based on how often you work out, since you are expelling water when you sweat. You should add 12 ounces of water to your daily total for every 30 minutes that you work out. So if you work out for 45 minutes daily, you would add 18 ounces of water to your daily intake.
To make it a littler easier to calculate how much water to drink everyday, here are the recommended amounts for a range of weights. Remember to adjust for your activity level.
