What I Felt: There have been times, especially during hot summer runs (but occasionally even in winter), where I’ve felt light-headed. At first, I couldn’t figure out why. Eventually, I realized it often boiled down to hydration—or sometimes a lack of fuel.
What I Did: Now, I make sure to hydrate properly before, during, and after my runs. I use electrolyte solutions to keep my hydration on point such as Nuun. For longer runs or those with a faster pace, I make sure to take in enough calories.
What the Experts Say: Experts suggest drinking fluids with electrolytes, especially if you’re sweating a lot. They also recommend fueling properly before and during exercise, maintaining blood sugar levels to avoid that dizzy feeling.
