It's Hot: Humid vs. Dry Heat

It's Hot: Humid vs. Dry Heat

Unless you live in the Southern Hemisphere, you’ve probably been enjoying the steady rise in outdoor temperatures. Gone are the 100(+) inches of snow in Boston, as well as the single-digit temperatures most of us dealt with in January. In its place is lovely spring-time weather, meaning you no longer have to grit your teeth in order to get out the door and train. However, summer is around the corner, and with it … summer heat. It’s about to get hot. Very hot. And if it’s not hot, it will be humid, which still feels awful. (We’ll explain why in a second…) Just as running in sub-freezing temperatures takes a certain kind of toughness, running in the heat requires extra mental and physical stamina. It also requires a different approach to training and nutrition. Generally speaking, there are two kinds of hot: dry hot, in which humidity levels are at...

Why You're Craving Salt (And What To Do About It):

Why You're Craving Salt (And What To Do About It):

We’ve all been there: A craving for something strong. It’s not sugar -- sweet foods sound unappealing. No -- we want savory. We want feel-good comfort food. We want salt. As we explain in this blog post, a salt craving is your body’s way of telling you that you need salt. That’s a pretty basic observation, but someone can need salt for a variety of reasons, which require a variety of different solutions. As you’ll see, some are common (such as mild dehydration or excessive hydration) and some are severe (such as Addison’s disease). Make sure you correctly identify the problem and then you’ll be able to employ the correct solution. Let’s jump in!   Reason 1: You’re dehydrated or over-hydrated: Think back to the last time you went for a long run in the heat. When you finished, your face and body were coated in a thick, salty layer....

These Are the Symptoms (and Causes) of Hyponatremia

These Are the Symptoms (and Causes) of Hyponatremia

“Replacing lost stores is essential but rehydration can be overdone,” begins a 2007 article in Scientific American. “There is such a thing as a fatal water overdose.” While this article does not mark the beginning of medical concerns regarding hyponatremia, it did come at a time when this dangerous condition -- marked by unnaturally low sodium levels in the blood -- began to see increased media attention. Tweet this post! Stay Aware This Summer! These Are the Symptoms (and Causes) of Hyponatremia: http://bit.ly/1Ypn1uM via @SaltStick In the last decade, several deaths have resulted from radio-hosted water-drinking contests that prompt the contestants to consume gallons of water at once. The running community has suffered losses as well: In 2002, a man collapsed in the Boston Marathon, eventually dying of “drinking too much water,” as described in press coverage of the tragedy. In 2007, a similar death occurred in the London Marathon....

Do Electrolytes Help Prevent Cramps?

Do Electrolytes Help Prevent Cramps?

If you are an avid consumer of endurance media (like we are!) you have probably noticed the uptick in articles related to the science behind anti-cramping. Recently, many articles, including paid, native advertising placements in Triathlete Magazine and other articles in Outside Magazine, report new research into the link between cramping and neural activity. Arguing there is no association between hydration and cramping, the articles suggest that instead of electrolytes, the true cause of cramps is an interruption of “ion-channel receptors,” which control how electrical signals are transmitted between cells. “Some studies showed that drinking pickle juice or eating mustard helped prevent ,” writes Outside Magazine in a recent September article. “Pickle juice and mustard contain molecules called ion-channel activators, which trigger nerves in the digestive system. These activators are why spicy foods feel hot: they don’t burn you, but they trigger the same nerve response that occurs when you...
