When sweating it out at the gym or on a run, you may find that your sweat tastes salty. Although this is all a completely normal part of the body’s cooling process, you might be wondering whether salty sweat is something to worry about.
Here’s what to know about salty sweat and how it might affect your health during exercise.
Salty Sweat: Why Does It Happen?
Sweat, produced by the sweat glands, is used to cool the body following exercise or heat exposure. Sweat is composed of water, electrolytes (like sodium, potassium, and chloride), and small amounts of other waste products, such as urea. Sodium, the most prevalent electrolyte in sweat, is what makes it salty.
This salt is necessary for countless functions in our body, including nerve signaling, and keeping the right amount of fluid in the right place. Although most individuals’ sweat is mildly salty, some might notice saltier-tasting perspiration, particularly after vigorous physical exertion or extended sweating.
Healthy or Not?
On the whole, salty sweat is not cause for concern. This is just a signal that your body is optimally regulating its temperature by sweating out extra heat. But your body’s salt levels during exercise are a different story.
Excessive Sweating and Electrolyte Loss
If you are exercising at your max or for long periods, especially in hot or humid conditions, you are likely sweating more than normal. Now, although sweat helps cool the body down, excessive sweating causes not only the loss of water but also the loss of valuable electrocytes like sodium. Such a depletion of electrolytes can lead to dehydration, muscle cramps, dizziness, and fatigue.
For those who participate in endurance athletics or strenuous workouts, keeping electrolyte levels balanced is essential for maintaining energy and avoiding these symptoms.
Salt Crystals on Your Skin
You may notice white telltale salt crystals on your skin after a long workout or run. Although this is simply the sodium in your perspiration crystallizing on your skin, the appearance of these crystals can indicate that your body has lost a considerable amount of salt. If this pattern is repeated often, then it could mean you need an electrolyte-packed drink after sustained physical activity to refill the salt you may have lost.
When Should You Be Alarmed?
Salty sweat is typically nothing to worry about, but there are a few unusual situations where it could be a sign of something else going on:
Cystic Fibrosis
Cystic fibrosis is a genetic condition that impacts the sweat glands, resulting in a far saltier than normal sweat. People with cystic fibrosis can lose large amounts of salt in their sweat, resulting in imbalances of electrolytes. If you find that your sweat is unusually salty, you may want to consult a healthcare provider to rule out this condition.
Electrolyte Imbalance
In rare instances, if you’re sweating a lot and not properly replacing lost electrolytes, you can develop an imbalance. If sodium levels are low, symptoms including cramping, dizziness, nausea and fatigue can occur. If you feel like this often after working out, you need to replace both the water and electrolytes you lose, as this can cause serious problems.
How to Balance Your Salty Sweat During Exercise
Try these tips to keep your hydration and electrolyte levels on track while getting your sweat on:
Hydrate Before and After: Make sure you’re hydrating properly, before, during and after your workout. If you’re doing long workouts or endurance activities, drink an electrolyte beverage (with sodium and potassium) to replace minerals you lose.
Opt for the Right Sports Drink: For workouts exceeding one hour or in especially hot conditions, try a sports drink with electrolytes from the grocery store, which can help replace lost sodium. Opt for one that is relatively low in sodium and has the other electrolytes balanced to avoid causing an electrolyte imbalance in your body.
Consume Salt-Rich Meals: Eating salt-rich meals after working out, such as a balanced meal with lean proteins and vegetables can help replace what goes out from your system and restore electrolytes balance.
In most instances, salty sweat is completely normal and not something to worry about. It’s just a sign that your body is doing what it should to cool you down and regulate its temperature while you’re exercising. But if you’re sweating buckets and feeling symptoms such as cramping or fatigue, it’s time to take some measures to replenish your lost electrolytes. By keeping hydrated with the right nutrients, you can keep salty sweat from ruining your workouts or health.
