Last time I made every mistake in the book hiking in 90°F + 80% humidity. By mile 3, I was dizzy, nauseous, and had to turn back. Here's what I learned the hard way (and what I'm doing differently now): 🔔The Game-Changers: 1️⃣ Start at 5 AM - I used to think this was overkill, but avoiding 10am-4pm heat is EVERYTHING 2️⃣ 1 liter per hour rule - I was drinking maybe half that. Now I track it religiously 3️⃣ Loose, light colors only - swapped my black shirt for light gray moisture-wicking. Huge difference! 4️⃣ Cooling towel around neck - sounds dorky but works like magic 5️⃣ Electrolyte tablets - water alone wasn't cutting it in that humidity ⚠️Red flags to watch for: Heavy sweating + weakness = heat exhaustion (turn back!) Hot, dry skin + confusion = heat stroke (emergency!) Dark yellow urine = you're already behind on hydration Trust me, your ego isn't worth heat stroke. Know when to call it and try again another day! #hiking #HikingTips #heatsafety #summerhiking
