Is Your Sodium Intake Affecting Your Hiking Performance?

Check out the diet label on a freeze-dried backpacking meal, and also you is likely to be shocked by how a lot sodium it comprises. Some meals pack greater than 1,500 mg right into a single pouch, roughly two-thirds of the really helpful day by day restrict of two,300 mg for many adults. That’s quite a bit for one dinner, however while you’re spending hours sweating your means up steep climbs, you’re additionally shedding sodium together with water.

Sodium helps regulate fluid stability and helps regular nerve and muscle perform. But there’s a contradiction in the way you may give it some thought on the path: you query the sodium in your freeze-dried dinner whereas including electrolyte powder to your water bottle and snacking on pretzels, jerky, and cheese.

So, are you consuming an excessive amount of sodium or not sufficient? The reply will depend on what’s already in your meals, how a lot you’re sweating, and the way you’re changing fluids.

Two Meals Baggage, One Massive Sodium Distinction

You may pack almost similar quantities of meals and find yourself with dramatically totally different sodium intakes. I in contrast two sensible days of backpacking meals, every containing business meals, protein bars, snacks, and different acquainted path staples. Each present roughly 3,150 energy and weigh about 23 ounces dry, but one comprises 5,465 mg of sodium whereas the opposite comprises simply 1,975 mg.

That’s almost 3,500 mg of distinction earlier than you add a single electrolyte packet. A few of the variation comes all the way down to particular person merchandise: Mountain Home Beef Lasagna comprises 1,180 mg of sodium, in contrast with 340 mg in Good To-Go Pad Thai. Even switching pretzel flavors or protein bar manufacturers could make a noticeable distinction. Neither meals bag is routinely higher, however the comparability exhibits why it’s value checking what you’re already carrying earlier than deciding to complement.

Too A lot Sodium Isn’t Innocent

Well being specialists suggest limiting sodium for a motive. Persistently consuming greater than your physique wants can increase blood stress, rising your danger of coronary heart illness and stroke over time. A very salty meal also can go away you thirsty or quickly bloated as your physique regulates its fluid stability. In the event you’ve been suggested to restrict sodium due to hypertension, kidney illness, or one other medical situation, these suggestions nonetheless matter while you’re backpacking.

However consuming a high-sodium eating regimen day after day isn’t essentially the identical as consuming salty meals throughout a strenuous backpacking journey. Once you’re sweating closely, you lose sodium you wouldn’t lose whereas sitting at a desk. That doesn’t imply each milligram of sodium in your meals is critical, or that it’s best to add electrolytes with out fascinated with what you’re already consuming. It merely means your exercise and situations matter when deciphering these numbers on the label.

Your Sweat Doesn’t Observe an Electrolyte Schedule

Even should you’re mountaineering alongside somebody on the identical path, you might be shedding very totally different quantities of sodium. Sweat losses rely on two issues: how a lot you sweat and the way concentrated that sweat is. Analysis has discovered sweat sodium concentrations starting from roughly 230 to 1,600 mg per liter. Temperature, exertion, clothes, warmth acclimatization, and particular person physiology all have an effect on your losses, which suggests mileage alone tells you little or no about how a lot sodium you’ve misplaced.

Right here’s one other wrinkle: shedding 800 mg of sodium by way of sweat doesn’t routinely imply you might want to eat 800 mg to exchange it. Your physique regulates sodium and water stability, and analysis suggests focused sodium alternative issues extra underneath sure mixtures of extended train, substantial sweat losses, and fluid alternative. That’s why taking an electrolyte packet each hour isn’t essentially applicable. A packet doesn’t account for the way a lot you’re sweating, how a lot you’re consuming, or how a lot sodium you’re getting from meals.

Your Dinner Isn’t the Solely Supply of Sodium

Sodium doesn’t have to come back from an electrolyte complement to depend. Salty snacks, meals, and electrolyte drinks all contribute to your consumption, though while you eat that sodium can matter throughout lengthy, sweaty days. Think about spending ten hours mountaineering in heat climate, sweating closely and consuming water however consuming little or no. At camp, you put together a freeze-dried dinner containing 1,500 mg of sodium. That sodium helps change losses and retain fluids throughout restoration, nevertheless it wasn’t out there in the course of the previous hours of mountaineering.

Consuming salty snacks all through a protracted, sweaty hike offers some sodium alongside the best way as a substitute of ready till dinner. That doesn’t imply you want electrolyte powder in each water bottle. In the event you’re recurrently consuming pretzels, cheese, jerky, or different salty meals, you’re already consuming sodium in the course of the day. Then again, in case your path menu comprises comparatively little sodium otherwise you wrestle to eat whereas mountaineering, an electrolyte drink could also be a handy different. What issues isn’t whether or not the sodium comes from a packet or a snack, however whether or not you’re including one thing your meals isn’t already offering.

Extra Electrolytes Received’t Repair Overdrinking

It’s simple to imagine that changing the sodium you lose by way of sweat will shield you from exercise-associated hyponatremia (EAH), a probably harmful drop in blood sodium. However in response to the Wilderness Medical Society, most circumstances happen primarily since you drink an excessive amount of fluid relative to your losses, typically mixed together with your physique’s tendency to retain water throughout extended train. Sweat sodium losses can contribute underneath some circumstances, however taking electrolyte dietary supplements gained’t stop hyponatremia should you’re overdrinking.

The rules suggest avoiding overdrinking, usually by consuming in response to thirst or utilizing fluid wants you’ve estimated from expertise in related situations. In addition they suggest having salty meals or drinks out there throughout lengthy, scorching actions. Complications, fatigue, nausea, and muscle cramps aren’t dependable indicators that you simply want extra sodium as a result of they’ll have a number of causes. In the event you or a mountaineering companion develops worsening confusion, repeated vomiting, seizures, or collapses throughout or after extended exertion, search pressing medical assist somewhat than assuming extra water or electrolytes will clear up the issue.

So, How A lot Sodium Do You Truly Want?

There’s no easy reply. Your sweat losses differ with the situations and your particular person physiology. Even understanding precisely how a lot sodium you lose wouldn’t let you know how a lot to exchange. For context, 1,500 mg per day is taken into account an sufficient consumption for many adults underneath atypical situations, whereas 2,300 mg is the final really helpful day by day restrict. Neither is a backpacking-specific goal. A meals bag containing 5,465 mg isn’t routinely extreme for a strenuous mountaineering day, simply as one containing 1,975 mg isn’t essentially insufficient. And since analysis hasn’t persistently proven that further sodium improves endurance efficiency, there’s little motive to chase a exact alternative goal.

The underside line? Hike your individual hike. In the event you’re inquisitive about your sodium consumption, monitor what you eat and drink, the situations you’re mountaineering in, and the way you are feeling throughout and afterward. You may discover patterns that allow you to plan future journeys, with out getting caught up in changing each milligram of sodium you sweat out.
