Top 5 Supplements for Heat Exhaustion


1
Sodium

Our final supplement -- the most important thing a human body needs next to water when facing heat exhaustion -- is sodium.

Depending on what you've heard, sodium gets a pretty bad wrap. And it's true that doctors suggest many Americans already consume an excess of sodium, much of which comes from processed foods. But sodium, specifically sodium chloride (table salt), is the No. 1 electrolyte that needs replacing when we sweat.

For someone experiencing heat exhaustion, excessive sweating is a common symptom. The body is trying to rapidly cool itself and will shed salt and water to do so. But even if you're drinking fluids, you can still succumb to heat exhaustion if they don't have enough salt in them [source: UMMC].

And as you may have guessed, sodium is the other important part of the equation in the sodium-potassium pump. See, molecular biology isn't that hard.

Like potassium, sodium is a soluble electrolyte added to sports drinks for rehydration [source: CDC]. These kinds of drinks are the quickest way to get both water and the aforementioned electrolytes back into your body.

Remember that a healthy diet including the daily recommended allowance of vitamin C, calcium, magnesium, potassium and sodium is the best way to stay fit when facing hot and humid weather.

And if you even think you're going to run into friends asking you to play a little roundball, make sure to grab your water bottle next time.
