‘Computer Kidney’ Suggests to Drink Enough Water Daily

“Incredibly, how mammals produce a highly concentrated urine is not well understood,” Layton said. “We’re now a step closer to understanding how water balance is maintained in mammals.”

Researchers at the University of Waterloo in Canada have developed a “computer kidney” that can help shed light on impacts of medicines taken by those who don’t drink enough water.

The ability of the kidney to maintain water balance is vital to our health. It controls water balance, and when we are dehydrated, it produces highly concentrated urine to get rid of waste using as little water as possible.

The older population, those with kidney diseases, and those on blood pressure medication sometimes have a problem with water balance.

The researchers found that the elderly people with impaired kidney function and those taking a combination of certain drugs need to be extra mindful of their water intake.

“People who have high blood pressure are typically given a water pill, so they pee a lot to lower their blood volume and in so doing lower their blood pressure,” said Anita Layton, professor of Applied Mathematics, Pharmacy and Biology at Waterloo.

These patients are frequently also given another drug that targets a hormonal system which will affect the kidney as well.

“A lot of people are on these two drugs, and they will be fine. But one day they might have a headache and take an aspirin, and the three of these drugs together can hurt your kidneys,” Layton added in a paper published in the the American Journal of Physiology – Renal Physiology.

Layton built the first computational model that simulates the muscle contractions that move urine from the kidney to the bladder.

It found that unless a patient is properly hydrated, taking the two blood pressure drugs and an aspirin concurrently could cause acute kidney injury.

Shaking head is one of the most common methods people use to get rid of water in their ears, but it can can also cause complications as Researchers have found that trapped water in the ear canals can cause infection and Brain Damage.

Researchers at Cornell University and Virginia Tech in US, revealed that shaking the head to free trapped water can cause brain damage in small children.

“Our research mainly focuses on the acceleration required to get the water out of the ear canal,” said Indian-origin researcher and study author Anuj Baskota from Cornell University.

“The critical acceleration that we obtained experimentally on glass tubes and 3D printed ear canals was around the range of 10 times the force of gravity for infant ear sizes, which could cause damage to the brain,” Baskota said.

For adults, the acceleration was lower due to the larger diameter of the ear canals. They said the overall volume and position of the water in the canal changes the acceleration needed to remove it.

“From our experiments and theoretical model, we figured out that surface tension of the fluid is one of the crucial factors promoting the water to get stuck in ear canals,” said Baskota.

Luckily, the researchers said there is a solution that does not involve any head shaking.

“Presumably, putting a few drops of a liquid with lower surface tension than water, like alcohol or vinegar, in the ear would reduce the surface tension force allowing the water to flow out,” Baskota said.
