Frequent Urination
Headaches
When you drink too much water, your cells don’t have enough sodium and potassium to balance things out. This leads to there being too much water for the cells to handle comfortably, causing problems in some organs. For example, when your brain cells are swollen, you can easily get a headache, if not other, more severe symptoms.
Dizziness
Abnormally Low Potassium Levels
Your potassium levels can drop when you drink too much water. This mineral is supposed to maintain healthy blood pressure, fluid balance, and muscle coordination. It needs water, but too much can be a bad thing. Nausea is a key sign that you’re suffering from hypokalemia, as this condition is called, so be sure to grab a banana.
Muscle Cramps
Overwhelmed Kidneys
Heart Strain
Exhaustion
Always Drinking
Lack of Sleep
Because you’re waking up so much to go to the bathroom, you will have trouble sleeping. Urination is definitely an easy way to tell if you’re drinking too much or too little, but if you’re having trouble sleeping at night, it’s probably a safe bet to assume you could stand to drink a little less, at least in the hours before bed.
