Taking Electrolytes When Running In Death Valley

Kenneth Posner:
"Salt/electrolytes

"I didn’t take any supplemental salt or electrolytes during the run. Further, the foods I consumed were generally low in sodium. None of my teammates took salt or electrolyte supplements.

"While the sports-drink industry markets the importance of electrolytes, Tim Noakes has argued that the body contains enough salt and electrolytes to last for weeks. Further, he points out that in a hot environment, the salt content of sweat and urine drops by 90-plus percent. People see white, crusty sweat on their clothes after running because their bodies are ridding themselves of the excessive salt contained in the typical western diet (Noakes 2012). Ironically, people see the salt crusts and, worrying that they are running low on electrolytes, eat more salt—when they actually may have more than they need.
Talk about putting your money where you mouth is!

If you can run 292 miles through Death Valley without supplementary salt, I think we can put that myth to bed.

Iatrogenic Ebola?

"iatrogenic /iat·ro·gen·ic/ (i-ă´tro-jen´ik) resulting from the activity of physicians; said of any adverse condition in a patient resulting from treatment by a physician or surgeon."
I was surprised to read this:

"In the end, you discovered that the Belgian nuns had unwittingly spread the virus. How did that happen?

"In their hospital they regularly gave pregnant women vitamin injections using unsterilised needles. By doing so, they infected many young women in Yambuku with the virus. We told the nuns about the terrible mistake they had made, but looking back I would say that we were much too careful in our choice of words. Clinics that failed to observe this and other rules of hygiene functioned as catalysts in all additional Ebola outbreaks. They drastically sped up the spread of the virus or made the spread possible in the first place. Even in the current Ebola outbreak in west Africa, hospitals unfortunately played this ignominious role in the beginning."

From here, 'In 1976 I discovered Ebola - now I fear an unimaginable tragedy'

Lovely.
