Beat the Heat: Why Magnesium and Salt Are Your Summer Energy Secret
Summer's Hidden Drain on Your Body
June kicks off the season of long days, outdoor adventures, and rising temperatures. While we tend to think of summer as our most energizing time of year, it is also when many of my patients quietly start feeling more fatigued, foggy, crampy, or lightheaded. The culprit is rarely the heat itself. More often, it is the loss of two foundational nutrients that summer depletes faster than any other season: magnesium and salt.
In functional medicine, we look at the body as an electrical system. Every heartbeat, muscle contraction, nerve signal, and thought relies on minerals to conduct energy. When we sweat, we are not just losing water. We are losing the very minerals that keep that electrical system running. Replacing them properly is one of the simplest and most overlooked summer wellness strategies.
Why Magnesium Matters More in the Summer
Magnesium is involved in over 300 enzymatic reactions in the body, including energy production, muscle relaxation, blood sugar regulation, nervous system balance, and sleep quality. Even in cooler months, the majority of adults do not get enough. Add in summer sweat, increased activity, sun exposure, and the dehydrating effects of alcohol or caffeine, and magnesium levels can drop quickly.
Common signs of low magnesium include muscle cramps, twitching eyelids, headaches, poor sleep, anxiety, constipation, and that wired but tired feeling at the end of the day. Replenishing magnesium consistently can support smoother muscles, calmer nerves, deeper sleep, and steadier energy throughout the heat of the season.
The Truth About Salt
Salt has gotten a bad reputation, but the right kind of salt is essential, especially in summer. When you sweat, you lose sodium along with other electrolytes. If you only replace the water without the minerals, you can actually dilute your system and feel worse, experiencing dizziness, fatigue, brain fog, or headaches even though you are technically hydrated.
Unrefined mineral salts such as Redmond Real Salt, Celtic sea salt, or Himalayan pink salt contain sodium along with trace minerals that support adrenal function, blood pressure regulation, and cellular hydration. A pinch of quality salt in your water, especially first thing in the morning or after time outdoors, can dramatically improve how you feel. *Also, a quick note I learned from our wellness coach, adding a sprinkle to one teaspoon of cream of tartar is a wonderful way to replenish potassium, which often gets depleted alongside these other minerals.
A Simple Summer Hydration Strategy
Rather than chugging plain water all day, focus on mineral-rich hydration. Start your morning with a glass of water containing a pinch of unrefined salt and a squeeze of lemon. Add a quality magnesium supplement, such as magnesium glycinate or threonate, in the evening to support sleep and muscle recovery. Sip electrolyte-rich beverages during outdoor activity, and include magnesium-rich foods like leafy greens, avocado, pumpkin seeds, and dark chocolate in your meals.
Listen to Your Body This Season
Summer should leave you feeling vibrant, not depleted. If you are experiencing fatigue, cramps, poor sleep, or that drained feeling after time in the sun, your body may simply be asking for more minerals. Supporting magnesium and sodium levels is one of the most accessible, affordable, and effective ways to enjoy the season at your best.
Sweat Smarter with Sunlighten Sauna
If you want to take your summer wellness routine to the next level, consider adding regular sessions in our Sunlighten infrared sauna. Infrared sauna therapy supports detoxification, circulation, recovery, skin health, and stress resilience, all while you simply relax and sweat it out. Unlike traditional saunas, Sunlighten uses gentle infrared wavelengths that heat the body from the inside out, creating a productive sweat at more comfortable temperatures.
Because sauna sessions promote deep sweating, your mineral needs go up, which makes pairing each session with quality electrolytes essential. Hydrating with magnesium and salt before and after helps you replenish what you lose, prevent fatigue or lightheadedness, and get the most out of every session.
