4. Can You Overdose on Water?
While rare, it is possible to drink too much water. The Journal of Clinical Pathology notes that fatal water intoxication is most commonly linked to psychiatric conditions in which an individual compulsively drinks too much water. If a person consumes gallon upon gallon of water in a short period of time, the electrolyte balance in the body is thrown off. This can result in dangerously low levels of sodium in the bloodstream. Low sodium levels, called hyponatremia, can cause nausea, vomiting, brain swelling, and death.
3. Instances When You May Need More Water
Staying in tune with your body and drinking water when you are thirsty and stopping when you are satisfied should fulfill your hydration needs. In certain circumstances, you may need more water than others. If it is a particularly hot day, the air conditioning breaks down, or you are engaging in intense physical exercise, be sure to keep a water source close at hand. Additionally, fever, vomiting, and diarrhea can deplete your body of its water stores. Drinking additional quantities of water while suffering from a UTI will dilute bacteria in your bladder and help flush them from your system.
2. What About Sports Drinks?
The abundance of sports drinks and rehydrating beverages on the market may make you wonder whether you should be drinking more than just plain water. These beverages contain sodium, potassium, and carbohydrates in addition to water. While these drinks may be beneficial after a long and strenuous workout, for the most part, they do not have any great benefit over drinking plain water. In fact, they may contain large amounts of sugar and contribute to weight gain. At zero calories, plain water provides your body with the hydration it needs without the risk of packing on pounds.
