Can Water Be Harmful For You?

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

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.

“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)

Google Takes Initiative To Clean And Make Our Planet Healthy

The tool suggests simple changes-like installing a low-flow showerhead and fixing common household leaks-that can help you be more water smart.

Google has teamed up with the California Academy of Sciences to launch an interactive new tool that will help reduce environmental footprint by informing the amount of water your shower uses or the impact of throwing away food or turning down the water heater by a few degrees.

The tool called Your Plan, Your Planet is an interactive way to understand your environmental impact and learn simple, science-based ways to improve it.

“We all want a healthy planet. The small choices we make each day can help us get there. Learn simple tips from Google and the California Academy of Sciences to leave the earth in better shape,” Google said in a blog post late on Friday.

“Our greatest impact on the planet comes from just three things: our food, water, and energy usage. And if we each made a few small changes, we could all make a big difference,” wrote Jill Puente, Planet Earth Advocate, in the blog post.

Food production accounts for more than two-thirds of the world’s water use, and over a quarter of carbon dioxide emissions.

Your Plan, Your Planet, shows the water and carbon impact of what people eat and gives them smart ways to store it so that less food ends up in the trash.

Much of the energy we use comes from burning natural resources, which in turn releases CO2 into the air. But easy tweaks, like washing laundry on a cold and adjusting the thermostat just a few degrees, can reduce the impact in a big way, Puente noted. (IANS)
