What are the harms of carrying water bottles?

People usually carry a water bottle with them when they go out. Sometimes, the bottle is their company and they are attached to it. However, health experts have warned those people who carry a water bottle. 

If you are one of them, then you may listen to these experts.

It is healthy to stay hydrated and maintain water intake for the smooth function of the body but drinking too much water may cause you serious harm leading to a fixation on hydration, according to health experts.

A nephrologist at the Mayo Clinic in Rochester, Minnesota Dr Kambiz Kalantari said: “It’s not easy to overwhelm your kidneys. But there are situations in which people are obsessed with drinking water. … We’re talking about 10, 15 liters that overwhelm their kidneys.”

There are some tips to keep your water intake in check and mitigate the risk of over-hydration.


There is an old saying about how much water one should drink that does not fit every person as there is a difference in physique, activity, and other factors.

According to a recommendation from the National Academy of Medicine, 3.7 liters of water for males and 2.7 for women in a day. This suggestion also includes sources other than only water, such as beverages and food.

On the other hand, the Mayo Clinic recommended drinking 8 cups a day as it is easy to remember and typically keeps hydration levels balanced.

Nevertheless, it depends on how much water one needs.

Dr Kalantari said that it is not necessary to forcefully drink if not thirsty.

“Drinking too much water would cause kidneys to excrete the excess fluid, resulting in a lot of urination,” Dr Kalantari added.

If a person has difficulty in excreting the fluid out when the kidneys are overwhelmed, it may cause a person to visit the hospital.

According to Dr Kalantari, there are limits to the amount of fluid kidneys are able to excrete if a person has not eaten enough food that day.

Dr Ryan Bober, an internal medicine specialist with Cedars-Sinai in Los Angeles, said: “If you start to get to the point where you don’t really have much of a thirst mechanism then you’ve kind of pushed yourself into the range of overhydration.”

Water intoxication

When the excess amounts of water from the body cannot be removed from urinating or sweating, it causes water intoxication causing hyponatremia, in which the blood’s sodium level is less than normal.

The symptoms of intoxication may include irritability, confusion, vomiting, nausea, and in most critical cases, seizures and comas, or even death, according to Dr Bober.

The mild cases of overhydration typically resolve when a person ceases drinking water and the excess amounts make their way out of the body.

According to CNN, researchers in their 2022 study theorised that martial artist and actor Bruce Lee lost his life from hyponatremia, citing “high chronic fluid intake,” marijuana use that increases thirst, and prescription drug and alcohol intake that can affect the kidneys.

Dr Bober said: “The emotional support water bottle has its perks, but even drinking water needs to be in moderation — and the reusable bottle should be cleaned regularly.”
