How much water is too much to drink? a person needs can vary based on factors like age, weight, activity level, and climate. Generally, the recommendation is to drink about 8 glasses of water a day, which is roughly 2 litres or half a gallon. However, it's important to listen to your body and drink when you're thirsty.

Drinking too much water can lead to a condition called water intoxication or hyponatremia, where the balance of electrolytes in your body is disrupted. Symptoms can include nausea, vomiting, headaches, and in severe cases, even seizures or coma.

To avoid drinking too much water, it's helpful to pay attention to your body's signals. Thirst is a good indicator of when you need to drink more, and the colour of your urine can also give clues—pale yellow generally indicates you're well-hydrated, while darker yellow may mean you need more fluids.

In conclusion, while it's important to stay hydrated, it's also important not to overdo it. Listening to your body's signals and drinking when you're thirsty is a good way to ensure you're getting the right amount of water for your individual needs.
