Excessive Heat: What It Really Does to Your Body & How to Stay Safe

Summer heat warnings have never been more urgent. While most people reach for a glass of water when they feel drained, the truth is that excessive heat does far more than cause thirst — it disrupts your hormones, depletes critical minerals, slows digestion, and triggers a cascade of inflammation that most people mistake for everyday fatigue.
At iThrive Healing & Beyond, we've spent years working at the intersection of functional nutrition and real-world health. Every summer, we observe the same pattern: clients arrive exhausted, inflamed, and frustrated — not knowing that their body has been fighting heat stress long before any classic "heat stroke" symptoms appear.
