We\u2019ve seen record-breaking temperatures<\/a> this summer, putting millions of Americans at risk of heat-related health issues. This can include cramps, dehydration, heat exhaustion, heat stroke and even death.\u00a0<\/p>\n So if you\u2019re spending any time outdoors it\u2019s important to keep a few safety tips in mind.<\/p>\n Whether you’re cheering from the sidelines at your kid’s baseball game, squeezing in that after-work pickleball match or prepping for a weekend of trail hiking and camping, monitoring your hydration isn’t just about comfort, it’s about safety. But chugging water isn’t always the complete answer. Here\u2019s where, when and why electrolyte supplements may need to be an additional part of your hydration strategy.<\/p>\n The Weather Company does not provide medical advice, diagnosis, or treatment.

Hypotonic:<\/strong> A large portion of electrolyte powders are hypotonic. This means it has a lower concentration of dissolved particles (like sugar and salt) than your blood, allowing water to move rapidly from your gut into your bloodstream. It absorbs the fastest with the lowest amount of carbohydrates.<\/p>\n 2. Isotonic:<\/strong> These are designed to match the natural concentration of salt and sugar in your blood for balanced absorption.<\/p>\n 3. Hypertonic:<\/strong> These electrolyte solutions have higher concentrations than your blood. They are designed to absorb slower but deliver more per sip, and pull water out of the cells<\/a> into the bloodstream.<\/p>\n Common Electrolyte Ingredients<\/p>\n As you skim through the ingredient lists<\/a> on your electrolyte packets, drinks or tablets, here are a few ingredients that are considered essential, nice-to-have and those that could cause some stomach issues when taken in volume.<\/p>\n After all, sometimes there can be too much of a good thing with a surplus of vitamins and minerals that you may not necessarily need, so it\u2019s important not to overload on electrolytes. You don\u2019t typically need an electrolyte supplement every day unless you\u2019re exercising and sweating rigorously, or recovering from illness.\u00a0<\/p>\n Common side effects<\/a> could see increased blood pressure, upset stomach, irritability, muscle cramps and headaches.<\/p>\n So when in doubt, be sure to check with your physician before you take any electrolyte supplements.<\/p>\n What to avoid:<\/p>\n Best Electrolyte & Hydration Supplements of 2026<\/p>\n We\u2019re rounding up some of the best electrolyte options for the three main categories, including hypotonic, isotonic and hypertonic ingredient lists.
