Can You Drink Too Much Water? MDs Explain What Happens When You Overhydrate Water

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. Lack of water can lead to dehydration — a condition that occurs when you don’t have enough water in your body to carry out normal functions.

Drinking too much too quickly can affect breathing, heart rate, body temperature and gag reflex. The right amount of water you should consume per day can vary, but in general, adequate water intake for healthy people are based on age and sex. As a baseline, adult women need about 11.5 cups of total fluid per day and adult men need about 15.5 cups.

There’s no exact data on what level of sodium in the blood causes these early symptoms—it probably varies from person to person.

Common situations such as extreme heat, significant activity, and illness with fever may require more fluid intake than average.

Who’s at risk?

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.

“This occurs when you consume an excessive amount of water that dilutes the sodium levels in your blood,” he tells Bustle. Symptoms of water toxicity include nausea, https://sober-home.org/ vomiting, headache, confusion, and in severe cases, even seizures or coma. This is why it’s so important to figure out how much water your body actually needs.

How To Stay Hydrated Throughout The Day

Usually, water toxicity occurs along with an underlying medical condition that causes the kidneys to retain fluid. Most people, especially those who exercise in hot weather, are concerned about not drinking enough water. This is when your body’s water is more than your kidneys can excrete. Health conditions like kidney disease and pregnancy can also alter the amount of water a person should drink each day. Certain medications can affect the body’s fluid balance, too. Even your own individual hydration needs can change from day to day.

• Doing so will make it less likely to affect your body’s ability to absorb iron from your food at mealtimes.

• When you drink too much water, your kidneys reach a point where they’re unable to get rid of the excess liquid.
• There’s no exact data on what level of sodium in the blood causes these early symptoms—it probably varies from person to person.

Your kidneys are responsible for filtering the water you drink through your body and making sure the fluid levels in your bloodstream stay balanced. When you drink too much water, your kidneys have to work even harder, creating a stressful reaction from your hormones that leaves your body stressed and fatigued. If you’re constantly drinking water and find yourself struggling to get out of bed, it may be because you’ve added unneeded stress to your kidneys. If you carry around your water bottle all day and immediately refill it when it depletes, you may be drinking too much water. Constantly adding water to your body can result in low sodium levels in your blood, which, according to the Mayo Clinic, can cause the cells of your body to swell.

Nausea

Drinking too little can lead to dehydration which can cause a range of symptoms from dizziness to, in some extreme cases, death. Drinking too much also has potentially dangerous impacts because too much water in the body affects the body’s electrolyte balance, experts said. They shared advice for how much a person should be drinking and the signs someone has had too much water — and if the right balance exists for the average water drinker. As such, it’s rare to experience dangerous side effects from drinking coffee, Dr. Hughes said. Caffeine overdoses typically result from taking in too much caffeine from concentrated forms, such as powders or supplements, in a short period of time, she said.

You Have a Headache or Brain Fog

The right amount differs, depending on factors such as body weight, level of physical activity, the climate, and whether they are breastfeeding. It is most common among people with schizophrenia, but it can also arise in people with affective disorders, psychosis, and personality disorders. This can affect the brain stem and cause central nervous system dysfunction.

Sodium is the electrolyte most affected by overhydration, leading to a condition called hyponatremia. Sodium is a crucial element that helps keep the balance of fluids in and out of cells. When its levels drop 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. No upper limit for water has been established because, in healthy people, the kidneys are able to excrete approximately 0.7 liters of fluid per hour to maintain proper fluid balance. However, to avoid water toxicity, experts advise never drinking more than 48 ounces (1.5 quarts or six cups) per hour.

If you’re healthy, it’s unlikely that you’ll develop serious problems as a result of drinking too much water. “The kidneys will excrete all of the excess water fairly promptly,” Maesaka says. However, the general rule is that the kidneys can only excrete about 1 liter an hour. So the speed at which someone drinks water can also change the body’s tolerance for excess water. If you regularly find yourself drinking a lot of water over a short period of time, there are a few general rules that can help you avoid water intoxication. If you or someone else is showing any signs or symptoms of water intoxication, especially seizures or drowsiness, it’s best to seek immediate medical attention.

This is where things can get tricky, Jason Ewoldt, a registered dietitian with the Mayo Clinic, said. Many of the symptoms of overhydration can be confused with the symptoms of dehydration. When the electrolyte levels drop because of drinking too much water, your body balance goes down.

There aren’t any firm guidelines about how much water can kill you, but drinking more than a liter (L) or so per hour for several hours isn’t something doctors recommend. If you’re feeling thirsty, the chances are that you should be drinking more water. Drinking too much is not a common problem and the average, healthy adult should focus on hydration, health experts told CBS. “If you have too much water, it’s going to basically push that water into cells to kind of balance out that sodium and other electrolyte concentrations,” Polavarapu said.
