Get your electrolytes
There have been a couple of times—doing CrossFit in the middle of summer in Texas, and doing hot yoga several times a week in New York—where I’ve experienced being electrolyte-deficient.
It shows up as extreme fatigue, brain fog, headaches, cravings, and a “wired but tired” feeling.
Especially if you’re active and in hot climates, be sure to get some high-quality salts (sea salt, Himalayan), mineral-rich foods (leafy greens, beans, nuts), and/or low-sugar electrolyte drinks. I get the Liquid I.V. electrolyte packets.
