So why do we want something salty instead of something sweet or savory?

There might be a physiological reason why you reach for the Doritos to snack on instead of that candy bar when your stress levels are rising.

In fact, animal research from the University of Florida suggests that consuming salt can actually decrease the amount of stress hormones like cortisol that are released during psychological stress.

And it’s likely that a similar effect takes place in humans, too, said one of the lead researchers Eric Krause, Ph.D.

You don’t need a lot of the salty stuff for this to happen, either: Raising your body’s sodium levels by just 1 to 2 percent is enough to suppress the production of your stress hormones, he says. 

A personal-sized bag of potato chips might be enough to get you to that level, Krause explained. 

What’s more, Krause and other researchers have found that the body’s oxytocin levels—a feel-good hormone associated with pleasure and comfort—increase when salt levels increase, too.

Go ahead and grab a small salty snack next time you’re stressed, but watch your portions: Many salty options, like chips and fries, tend to be high in fat and calories.
