Summer is in full swing here in the Northern Hemisphere, and as such, we're all sweating a bit more than usual. And while we're not complaining about the summertime sun, we should talk about the loss of electrolytes we can experience in summer—plus what to do about it. Here's what to know.
It's no secret that we sweat more in the summer, but what we might forget is the impact sweating can have on our electrolyte levels. As research published in the journal Sports Medicine1 explains, water and electrolytes are both lost as a consequence of thermoregulatory sweating, "and in some situations, especially when exercise is prolonged, high-intensity, and/or in a hot environment, sweat losses can be sufficient to cause excessive water/electrolyte imbalances and impair performance."
Electrolytes are essentially a category of electrically charged essential minerals that the body both produces and derives from food and beverages. As leading functional medicine physician Bindiya Gandhi, M.D., previously told mindbodygreen, minerals like calcium, magnesium, potassium, phosphate, chloride, and sodium are all examples of important electrolytes.
"You mostly lose sodium and chloride in terms of the electrolytes lost in sweat," mindbodygreen's vice president of scientific affairs Ashley Jordan Ferira, Ph.D., RDN, explains. "But don't forget about these electrolytes (and essential minerals!) you also lose—calcium, potassium, magnesium."
According to Gandhi, electrolytes are important for sustaining a healthy body and mind, as they help to balance our fluid levels; help to keep our muscles, nerves, heart, and brain cells working; and even help to transport nutrients to our cells.
Sounds obvious, but if you're sweating, that means you're losing water and you'll want to replenish it. It's never a bad idea to up your water intake, but it's especially important in the summer when you're more likely to be dehydrated. And of course, if your water has electrolytes mixed in, even better—which brings us to our next point.
Along with making sure you're drinking enough water, you might want to add electrolyte packets into the mix. There are a ton of options available that can help fortify your water with vitamins and minerals, but if you're unsure which to choose, here's a roundup of our favorite electrolyte powders.
Last but not least, to make up for any minerals lost in sweat, be sure to eat plenty of mineral-rich foods on the daily. Here are some of our faves to keep in mind during your next trip to the grocery store:
The more you sweat, the more you'll want to pay attention to your electrolyte levels. Whether you're an everyday athlete or you're just sweating more in the summer heat, when in doubt, drink more water and up those vitamins and minerals!
Why are electrolytes important during hot weather and increased sweating ?
Electrolytes like sodium, potassium, and magnesium help maintain hydration and balance essential bodily functions, crucial during excessive sweating to prevent dehydration.
What are the best sources of electrolytes to replenish during hot weather ?
Foods rich in electrolytes include bananas, coconut water, leafy greens, and sports drinks. Additionally, electrolyte supplements or tablets can be helpful.
How much water should I drink to maintain electrolyte balance during hot days ?
It's essential to stay hydrated but not solely with water. Aim for a balanced intake of water and electrolyte-rich beverages, adjusting based on activity levels and sweat rate.
Can I get enough electrolytes solely through my diet during hot weather ?
While a balanced diet contributes to electrolyte intake, intense heat and extended exercise might require additional electrolyte supplements for optimal replenishment.
What are the signs of electrolyte imbalance during summer heat, and when should I seek medical attention ?
Symptoms like muscle cramps, fatigue, dizziness, or headaches can indicate an electrolyte imbalance. Seek medical help if symptoms persist or worsen despite hydration and electrolyte intake.
