Can You Drink Too Much Water?

pathmedical Wellness

We all need water. Every cell in the body needs water to function well. The problem arises when you drink too much water, which is called overhydration.

There’s no single formula to determine how much water you should drink daily. Most doctors recommend eight glasses a day as a good starting point. You should adjust your intake around this amount depending on your environment, exercise regimen, overall health, and conditions like pregnancy or breastfeeding.

When you drink too much water, you may experience water poisoning, intoxication, or a disruption of brain function. This happens when there’s too much water in the cells including brain cells, causing them to swell. When the cells in the brain swell they cause pressure in the brain. You may start experiencing things like confusion, drowsiness, and headaches. If this pressure increases it could cause conditions like hypertension and bradycardia.

Sodium is the electrolyte most affected by overhydration, leading to a condition called hyponatremia. Sodium is a crucial element that helps maintain the proper balance of fluids inside your cells. When your sodium level drops due to a high amount of water in the body, fluids get inside the cells. Then the cells swell, putting you at risk of having seizures, going into a coma, or even dying.

One of the best ways to determine if you’re drinking enough water is to monitor the color of your urine. It usually ranges from pale yellow to tea-colored due to the combination of the pigment urochrome and the water level in your body. If the pee is often clear, that’s a sure sign you’re drinking too much water in a short span.

Too many bathroom trips. Another sign is if you’re relieving yourself more than usual. On average, you should urinate six to eight times a day. Going up to 10 times is normal for water-drinking high achievers or people who regularly drink caffeine or alcohol.

Drinking water even when you’re not thirsty. A third way to avoid drinking too much water is to be aware of when your body needs it. The body can fight against dehydration by letting you know when you need to drink some water. Thirst is the body’s response to dehydration and should be your guiding cue.

The symptoms of overhydration can look like those of dehydration. When you have too much water in the body, the kidneys can’t remove the excess liquid. It starts collecting in the body, leading to nausea, vomiting, and diarrhea. Headaches can signify both hydration and dehydration. Excess water in the body causes the body’s salt levels to go down and the cells to swell. This swelling causes them to grow in size, and those in the brain press against the skull. This pressure causes a throbbing headache and may lead to brain impairment and trouble breathing.

Tiredness or fatigue. Drinking too much water causes your kidneys to work too hard to remove the excess amount. This creates a hormone reaction that makes you feel stressed and tired. If you can’t get out of bed after drinking too much water, it’s because your kidneys are overworking.

A large portion of the body is made of water, which is vital for cell function and life. Your body will alert you when it needs more water. When you drink too much, it can lead to fatal conditions. If you don’t know how much water you should drink daily, stick to the popular advice of eight glasses a day.
