For most of us, salt falls into the identical class as sugar—it tastes nice however we must be eating much less of it. Skipping the shaker can hold your coronary heart healthy and, vainly, it’s going to reduce bloating and optimize the work you’ve put in on the fitness center.
But chances are high, for those who’re studying this (and due to this fact perusing web sites and magazines on eating healthy and getting match), you most likely don’t have to forgo the mineral.
“Most Americans consume too much salt, but I’d bet men and women who pay attention to their diet and fitness are probabaly consuming too little salt, actually,” says sport physiologist Alex Harrison, Ph.D., a efficiency advisor at Renaissance Periodization.
And spurning sodium may very well be compromising your athletic efficiency—even for those who’re not running marathons or hitting two-a-days.
“Endurance athletes are notorious for under-consuming sodium, but it’s becoming more inclusive with the gym/HIIT group and ‘clean-eating’ camp,” says exercise physiologist and nutrition scientist Stacy Sims, Ph.D, senior analysis fellow on the University of Waikato in New Zealand.
If your go-to sweat session is within the weight room or CrossFit field, a sodium deficiency can really make your muscle tissues weaker, workouts more durable, and dehydration worse. Here’s why.
How Sodium Makes Or Breaks Performance
Low total-body sodium can result in hyponatremia (water intoxication—“common in gym-goers who are ‘super clean’ and drink excessive tea, water, or non-sodium containing drinks,” Sims says), GI misery (loss of urge for food, nausea, vomiting), neural points (muscle spasms or twitching that will not go away, muscular weak point), and excessive complications, she explains.

When it involves athletic efficiency, low-sodium causes two predominant issues: It leaves you dehydrated and weakens your muscle tissues.
Quick refresher on how dehydration works: Sodium helps retain fluid within the body, particularly blood plasma quantity.
“When sodium is low, dehydration results and the heart has to work harder to accomplish the same amount of work,” Harrison explains.
If your sodium shops are low sufficient to trigger reasonable dehydration—dropping 2 to 4% of your body weight—it’ll tax your coronary heart sufficient to have an effect on bodily efficiency, he says.
Aerobic efficiency (learn: cardio) is hit first because it requires extra quick blood pumping.
But over time, “one’s ability to recover from repeated anaerobic bouts of exercise (like multiple sets in the weight room) will start to be compromised,” Harrison provides.
The decreased blood quantity and better coronary heart price take their toll. What’s extra, the unwanted side effects of dehydration embrace dizziness and fatigue, which may severely put you in danger if you’re making an attempt to maneuver heavy plates and dumbbells.

The different hitch: Sodium is crucial for nerve conduction. Without sufficient of the factor, {the electrical} indicators in your body decelerate, which suggests your muscle tissues can’t fireplace as rapidly and the fibers gained’t contract.
“This makes the actual muscle ‘weaker’ in the work that it does, which translates to feeling fatigued and weak in a workout,” says Sims.
Plus, slower signaling means a slower flood of the vitamins that assist regenerate muscle (potassium, calcium, sodium), which results in slower bounce again. In different phrases, you gained’t be capable to go as onerous or heavy, set after set, within the weight room.
Who Exactly Needs More Salt?
For endurance athletes, supplementing the stuff is a no brainer. The extra (and longer) you sweat, the extra sodium you’re dropping. Harrison estimates round 75% of the space athletes he works with are under-consuming salt for his or her exercise degree (which falls round six to 20 hours per week). Adding extra again in would assist: A 2016 research in The Scandinavian Journal of Medicine & Science in Sports discovered novice triathletes improved each their end time and decreased their body mass loss once they took a salt complement earlier than and through a half-Ironman.
But even males who’re simply figuring out 3 to 5 hours per week don’t should be limiting their salt since “they’re already on the low end of what’s acceptable, or just mildly under-consuming salt,” Harrison provides. And similar goes for guys preferring throwing weights round. In reality, a current research within the Journal of the International Society of Sports Nutrition discovered when high-intensity strength athletes elevated their water and electrolyte consumption (based mostly on their private sodium loss), they had been capable of exert extra anaerobic energy, get better quicker, and enhance attention and consciousness.
So How Much Sodium Should You Aim For?
Both consultants agree there isn’t a one-size-fits-all suggestion for salt consumption. Unlike protein or carb consumption, “it varies enormous amounts with temperature, exercise type and duration, clothing type, and simply genetics of sweat ion concentration,” Harrison explains. For some, 1,000 to 1,500 mg could also be splendid, whereas for others, 10,000 mg nonetheless might not be sufficient on a really lengthy, sizzling endurance-training day. And your wants are completely totally different everyday, Sims factors out.
The excellent news is odds are low you’ll overdo it. Research exhibits solely individuals with high blood pressure want to fret about limiting their salt consumption and Harrison provides your kidneys will clear home and excrete the surplus sodium for those who over-consume, particularly amongst healthy people.

He advises aiming for a minimum of 1500 mg of sodium on all training days that clock in below an hour. Longer than that, Harrison recommends hitting 2300 mg that day, nearer to 4000+ mg for those who’re sweating for greater than two hours.
Sports drinks throughout and after training can actually assist, however the very best technique is together with extra sodium with actual meals all through the day, each consultants agree. That means evenly salting your food, throwing a splash of salt within the water you drink, and eating salty soups, Sims affords.
