How much should I drink a day? A healthy adult needs around 35 ml of water each day per kilogram of body weight .
According to the World Health Organization (WHO), an average adult needs to drink between 50 and 100 ounces (1.5 to 3 liters) of water per day. 64 ounces (1.8 liters) is considered ideal.
Most people need to drink roughly half of their weight (in pounds) in ounces. For example, a 200-pound adult needs approximately 100 ounces of water each day. Of course, your water needs will increase with any physical activity. So you'll need to add 12 ounces of water for every 30 minutes of daily activity.
The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.
A good rule of thumb is to drink 33ml per kilo of body weight. For example, if you weigh 55kg, you should drink 1.8 litres of water per day (0.033 x 55 = 1.815); if you weigh 90kg, you should drink 3 litres of water per day (0.033 x 90 = 2.97).
How much should I drink a day? A healthy adult needs around 35 ml of water each day per kilogram of body weight . At least according to the general guidelines from scientific organisations.
2 liters is 67.6 ounces, or about half a gallon (US).
Looking at it in the simplest way possible, a glass of water is already one cup, and a cup equals 8 ounces cups of water. So taking it eight times a day would be64 ounces of water, which is almost 2 liters.
Did you know that drinking 2 litres of water a day cleanses toxins from your body, gives you energy and helps with fatigue? Staying hydrated can bring a good dose of brain power and vitality to your day. It also helps your kidneys regain balance.
Here is one more reason to enjoy that morning cup of joe: “Coffee counts toward your daily water intake,” says Lauren DeWolf, MS, RD, a registered dietitian with Sharp Rees-Stealy Medical Centers. The water in coffee, tea and other caffeinated beverages helps us meet our daily fluid needs.
You'll feel less hungry and may even lose weight. You'll probably experience more comfortable digestion (less heartburn). Bowel movements might be easier and more regular. Your teeth and gums will be healthier and more resilient.
May Help Increase Your Metabolism
And some data shows that drinking water can increase the metabolic rate, meaning that it can stimulate more calorie burning at rest. This may, in turn, increase your daily energy expenditure and potentially result in weight loss.
The body needs water to function correctly, but drinking too much too fast can have serious health consequences. The kidneys can only remove 0.8 to 1.0 liters of water per hour, and a very high water intake can upset the body's electrolyte balance.
The average adult needs between 3-4 litres of water each day but drinking more than 800ml within an hour could be putting your kidneys in danger.
Water helps the kidneys remove wastes from your blood in the form of urine. Water also helps keep your blood vessels open so that blood can travel freely to your kidneys, and deliver essential nutrients to them. But if you become dehydrated, then it is more difficult for this delivery system to work.
Your skin and mouth will feel dry. You will be thirsty, you have a headache, and you will be constipated. You may feel dizzy or lightheaded and urine will be a dark yellow color. You will feel foggy brained and sluggish, and will constantly crave snacks and sugar.
As fluid intake increases, the amount of urine made will increase along with it. Because the bladder can only hold so much fluid volume, increasing water intake will increase the frequency of urination, and may make people with an overactive bladder more likely to leak.
Purifies the Body.
Drinking water plays a vital role in your digestion and drinking water on an empty stomach first thing in the morning loosens and expels bad bacteria, purifies the colon and allows for better and more efficient absorption of the nutrients that are in your system.
It's common skin issue that can be helpled by drinking enough water. Water can help flush toxins from skin and shrink your pores, making them less likely to clog and cause a zit.
So, on an average, consume 4-5 liters (women) or 6-7 liters (men) of water for weight loss (if you participate in vigorous workouts regularly and tend to sweat a lot). Also, water isn't the only factor.
Thus, one liter is equal to 4 glasses of water.
Here are some tips to help you make sure you are drinking enough fluids to maintain good levels of hydration. You are probably all aware of the “cardinal rule” that says adults should drink six to eight 8-ounce glasses of water per day.
