Drinking Too Much Water Can Harm You

Do you drink too much water? Beware, overhydration — excess fluid accumulation — can lead to dangerously low sodium levels or in the blood or result in brain swelling, researchers say.

Hyponatremia, a life-threatening condition of brain swelling, is more common in elderly patients and can cause cognitive problems and seizures.

“(Hyponatremia) occurs in common pathological conditions, including brain injury, sepsis, cardiac failure and in the use of drugs, such as MDMA (ecstasy),” said Charles Bourque from the McGill University in Canada.

While it was yet uncertain how hyponatremia develops, the study found that a defect in the hydration sensing mechanism of the brain could be the culprit.

The researchers said that brain’s hydration sensing neurons could not detect overhydration in the same way that they detect dehydration.

Overhydration activates Trpv4 — a calcium channel that can be found in glial cells, that act to surround hydration sensing neurons.

It is cellular gatekeeper implicated in maintaining the balance of water in the body.

“Our study shows that it is in fact glial cells that first detect the overhydrated state and then transfer this information to turn off the electrical activity of the [hydration sensing] neurons,” Bourque explained.

“Our specific data will be important for people studying hydromineral and fluid electrolyte homeostasis, and clinicians who treat patients faced with hyponatremia,” he noted.

The results, published in the journal Cell Reports, showed that overhydration is first identified by the Trpv4 channel which triggers the release of a type of amino acid known, taurine, which acts as a trip wire to inhibit hydration sensing neurons.

“Preclinical models of hyponatremia will be used to examine if the mechanism we report is affected in this condition with the long-term objective of designing new treatments or diagnostic tools,” Bourque added. (IANS)

Girls In Kenya Use Vapor Technology To Quench Their Thirsts

Community members, having seen the devices in use at the school, hope to acquire some of their own if they can find the funding.

In this arid part of northern Kenya, water can be hard to find, particularly in the dry season.

But a center run by the Samburu Girls Foundation – which rescues girls facing early marriage and female genital mutilation – has a new high-tech source of it.

Since June, the center, which has rescued more than 1,200 girls, has used panels that catch water vapor in the air and condense it to supply their drinking water.

“We used to have difficulties in accessing water and during a drought we could either go to the river to fetch water or ask our neighbors to give us water,” said Jecinta Lerle, a pupil and vice president of students at the center’s school.

But now, officials at the school say, the girls no longer have to travel for water – including into communities they have left, which could put them at risk.

“The girls can now have more time to study since there is enough fresh water to go round and there is no need to walk long distances to search for water,” said Lotan Salapei, the foundation’s head of partnerships.

Girls formerly trekked up to five kilometers a day in search of clean water during particularly dry periods, sometimes bringing them into contact with members of their former community, Salapei said.

The center, given 40 of the water vapor-condensing panels by the company that builds them, now creates about 400 liters of clean water each day, enough to provide all the drinking water the center needs.

The “hydropanels,” produced by U.S.-based technology company Zero Mass Water, pull water vapor from the air and condense it into a reservoir.

Cody Friesen, Zero Mass Water’s founder and chief executive officer, said the company’s project with the Samburu Girls Foundation was an example of its efforts to make sure the technology “is accessible to people across the socioeconomic spectrum.”

The panels provided to the Samburu Girls Foundation cost about $1,500 each, foundation officials said.

Zero Mass Water has so far sold or donated the panels in 16 countries, including South Africa.

Saving trees

George Sirro, a solar engineer with Solatrend Ltd., a Nairobi-based solar equipment company, said such devices can be a huge help not only to people but in slowing deforestation that is driving climate change and worsening drought in Kenya.

Often people with inadequate water cut trees to boil the water they do find to make it safe, he said, driving deforestation.

Philip Lerno a senior chief in Loosuk, where the girls’ foundation is located, said he hopes to see the panels more widely used in the surrounding community, which usually experiences long dry periods each year.
