Why do my fingers swell when I hike?


A few times while dayhiking, I have noticed that my fingers swell (water retention). Can you please explain what causes this?

Peripheral edema (fluid puffing up your hands, feet, and sometimes the face) is not terrifically unusual in backpackers. The causes can be many—pack straps that are too snug, for instance; gravity can also be the culprit in hands and feet. But the condition typically resolves harmlessly in short order, usually within hours to days. If the pack straps are the cause, you can experiment with a different pack, or try carrying more weight on the hip belt. Sometimes using a hiking staff or trekking poles helps reduce swelling in the hands. Sometimes the cause is never discovered, and you just have to live with it. If the swelling persists long after a hike ends, however, I suggest a visit to a doc. —Buck

    I second the electrolyte imbalance and firmly recommend the NUUN. I was actually quite surprised that Backpacker left it out from their list of electrolyte drinks in the last issue. It meets all their criteria. I love the grape flavor (it tastes like grape juice, not the color purple), the lemon tea, and the pink lemonade. They’re all great (kona kola takes a little bit of getting used to).
