When you drink too much water, especially in a short period, your kidneys may not be able to process and eliminate the excess fluid quickly enough. This excess water dilutes the sodium in your blood, leading to hyponatremia.
When you drink too much water, your kidneys have to work harder to process this excess fluid and eliminate it from your system. This can put a strain on them, especially if you have underlying kidney conditions.
Imbalances in electrolytes such as Potassium and Magnesium can contribute to muscle cramps, weakness, heart rhythm problems, and other health issues.
The brain is enclosed within the rigid structure of the skull. When brain cells swell, there's limited space for expansion. This increased pressure within the skull can disrupt brain function.
Drinking too much water can lead to several uncomfortable physical symptoms such as nausea and blotting.
In hyponatremia, the imbalance of sodium and water causes water to move from the outside of cells to the inside. This movement of water into the cells causes them to swell. This swelling can occur throughout the body, but it's particularly dangerous when it happens in the brain.
Excess water intake leads to increased urine production as the body tries to get rid of the extra fluid. This can be inconvenient, disruptive, and can lead to sleep disturbances if you need to wake up frequently during the night to urinate.
