If you're wondering how much water you should drink on those occasions, speak with your doctor, but a general rule of thumb for healthy people is to drink two to three cups of water per hour, or more if you're sweating heavily.
Keep Healthy by Staying Hydrated
To avoid becoming dehydrated, it's best to drink plenty of fluids — as much as 2-3 cups per hour — unless you are exercising or outside in the heat, then you'll need to consume more.
Your exercise habits affect the amount of water you should be drinking, as well. The American College of Sports Medicine recommends adding 12 ounces of water to your daily intake for every 30 minutes that you plan to work out. If you are exercising outside and it is very hot, you may need to add more.
To avoid hyponatremia, it is important not to outpace the kidneys by drinking more water than they can eliminate. The authors of the study report that hyponatremia symptoms can develop if a person drinks 3–4 liters of water in a short period, though they do not give a specific time estimate.
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.

Drink one glass of water 30 minutes before a meal to help digestion. Remember not to drink too soon before or after a meal as the water will dilute the digestive juices. Drink water an hour after the meal to allow the body to absorb the nutrients.
Sip water slowly than guzzling it down at once. Sipping water and allowing it to stay in the mouth and then passing through the food pipe helps the alkaline saliva reach the stomach to neutralise acid levels in the stomach.
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.
"The kidneys have limitations of how much water they can excrete at a time, which is a maximum of 800 to 1,000 milliliters per hour," says Koskinen. "Anything that exceeds that amount essentially waterlogs the body." When the body can't rid itself of excess water, cells swell to accommodate it.
Water is the ideal hydration choice because it moves quickly though your digestive system and into your tissues. Stay hydrated by sipping small amounts of water throughout the day; avoid chugging down fluids right before exercising to avoid stomach discomfort and bloating.
When you're overhydrated, you will notice some swelling or discoloration of your feet, hands, and lips. When the cells swell, the skin will also swell. Weak muscles that cramp easily. When the electrolyte levels drop because of drinking too much water, your body balance goes down.
Chugging as much water as you can all day is likely not the best or most efficient way to stay hydrated, and it's technically possible to overdo it. There is such a thing as overhydration that causes some unwanted and potentially dangerous side effects.
If you're dehydrated, the water will be absorbed and sent to maintain vital functions before it eventually reaches the kidneys to remove toxins. It generally takes your body 9 to 10 hours to produce 2 cups of urine.
The average person will take about 10 minutes or less for their body to process one glass of water because they have normal levels of bodily functions such as digestion and absorption.
The general rule is that the kidneys can only excrete about 1 litre an hour. Drinking excess water fast could lead to your kidneys not working properly. Too much fluid will dilute the amount of sodium in the bloodstream, leading to abnormally low levels.
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.
No, consuming only 1 liter of water per day is not recommended and can be dangerous. Being properly hydrated is key to overall health, so drinking the generally accepted 8–10 glasses of water per day is ideal.
Under the usual conditions of life, 3 – 4 liters of fluids a day will provide 2.5 to 3 liters of urine volume, and this is enough. The average healthy adult bladder holds about 1/2 liter, so this means 7 – 9 bathroom trips in 24 hours.
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.
