For most people, dehydration is the much greater issue. However, if you suspect you may be overhydrated, look for symptoms like cloudy thinking, nausea and vomiting, muscle weakness, spasms or cramps and headaches. In severe cases symptoms could include mental confusion, seizures, unconsciousness and even coma.
Water intoxication symptoms may include:
There is no set amount of water that causes water intoxication. The kidneys can process about one liter of fluid per hour, so any amount above that over a number of hours can be risky. Among healthy people, endurance athletes tend to be at greatest risk for overhydrating.
Symptoms of Overhydration
When overhydration occurs quickly, vomiting and trouble with balance develop. If overhydration worsens, confusion, seizures, or coma may develop. When overhydration occurs and blood volume is normal, the excess water usually moves into the cells, and tissue swelling (edema) does not occur.
Limit the amount of fluid you drink, often less than 4 cups (32 ounces) a day for several days. Sometimes, take medicines that make you urinate more (diuretics, sometimes called water pills) Be cared for in the hospital to adjust your fluids and electrolytes if they are severely out of balance.
Here are some ideas to consider:
Four liters of water a day might be too much for some, potentially causing dangerously low sodium levels (hyponatremia), especially if consumed quickly, though it can be fine or even necessary for very active people in hot climates, as individual needs vary greatly by activity, climate, and health. Healthy kidneys can process about 1 liter of fluid per hour, so rapid intake of 4 liters can overwhelm them, but spreading it out might be okay for some.
To exceed the body's ability to excrete water, a young adult with normal kidney function would have to drink more than 6 gallons (about 23 liters) of water a day on a regular basis.
Typically ingesting 1-2 liters or more within an hour of testing is sufficient to dilute most specimens for a 2–6 hour period. Diuretics such as caffeine and cranberry juice and some medications, including water pills may cause diluted urine samples.
Many people wonder how long it takes to pee after drinking water, but it depends on a variety of factors. Generally, it takes your body 9 to 10 hours to produce 2 cups of urine. A properly hydrated person with an almost full bladder will need to urinate between five to fifteen minutes after drinking water.
You should aim to drink water consistently throughout the day, with many experts suggesting about one cup (8oz or 250ml) per hour for the first 10 hours you're awake as a good baseline, rather than forcing yourself hourly or every two hours; this spaced intake prevents the body from excreting large amounts too quickly (a "bolus response") and helps maintain steady hydration, adjusting based on activity, climate, and thirst.
Drink at least 4 cups of water per day, gradually increasing to 8 cups of water per day. 3. When you get the urge to go, try to hold it for 5 extra minutes before going to the bathroom. Each week, add 5 minutes to the length of time you hold the urine after you have the urge.
We grab a bottle of water and guzzle it down, often in one go, to satisfy that thirst. But that's not really the best way to hydrate, says Lindsay Baker, PhD, a senior principal scientist at the Gatorade Sports Science Institute. “In general, it's best to sip a little bit throughout the day,” Baker says.
Although the concept of water-induced thermogenesis is open to debate and investigation, our study suggests drinking excessive water, when continued for 8 weeks, actually translates into body weight/fat loss, as depicted in Table 1, 2 and 3, possibly involving combination of thermogenesis, distention of ...
How much the colour of your urine changes will depend on how much food you eat or supplements or medication you take, how hydrated you are and on your own body chemistry. Sometimes a change in urine colour is an indication of a medical problem such as a urinary tract infection, or kidney, bladder or liver problem.
Drinking large volumes of just about any non-toxic water-based liquid will dilute urine. Drinking two or three 12-ounce glasses of water at the same time can produce 10-fold diluted urine within only half an hour and the dilution effect may last for hours.
Daily fluid intake
Most people should aim to drink enough during the day so their pee is a clear pale yellow colour. In the Eatwell Guide, the government recommends that people should aim to drink 6 to 8 cups or glasses of fluid a day.
However, if you suspect you may be overhydrated, look for symptoms like cloudy thinking, nausea and vomiting, muscle weakness, spasms or cramps and headaches. In severe cases symptoms could include mental confusion, seizures, unconsciousness and even coma.
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.

Overhydration Symptoms: 9 Signs of Drinking Too Much Water
Spring water is among the healthiest water to drink because it offers several benefits. It is naturally purified from an underground source, which means it is free of harmful contaminants like lead and chlorine. Since it does not undergo added filtration before bottling, it retains the beneficial minerals in the water.
Conclusion: Mild dehydration does not appear to affect sleep measures in healthy adults. However, fluid intake correlates positively with REM sleep length, sleep duration, and sleep efficiency, suggesting that the quantity of water consumed may influence sleep quality.
Steps
You can tell the difference between fat and water retention by doing a belly shake in front of the mirror. Expose your tummy, jig up and down, stop suddenly and see if the belly movement stops too or continues with a mini ripple. If it ripples then water retention is the issue.
