Summer Hiking in High Heat: Hydration, Pacing & the Bottle Kit

Trails in blazing sun, elevation, a pack on your back: summer hiking is magnificent — and it's the activity where people most underestimate their water loss. Here's the summer hiker's protocol, bottles included.

• 💧 The hiker's rule: 500ml to 1L per HOUR of walking in high heat — far more than thirst demands. Small sips every 15-20 min, not big gulps at breaks
• 🎒 The 2-bottle kit: bottle 1 = plain water; bottle 2 = diluted INTI (the ginger-lemon taste makes you drink, 0% sugar) + a pinch of salt if you sweat heavily — sodium and potassium leave in sweat
• ⏰ The right pacing: start before 9am, shade break 12-3pm, never big climbs in a heatwave afternoon — heat stroke on an isolated trail is a serious emergency
• 🔴 The summit trap: the « reward » lemonade or soda at the refuge (8-11g sugar/100ml) = spike-crash mid-descent, legs cut. INTI = freshness without the crash
• 🥾 The effort-nausea trick: elevation + heat + effort = a churning stomach for many; a sip of INTI calms exercise nausea — ginger's proven turf

The successful summer hike: 2 bottles (water + diluted INTI), 500ml-1L/hour in small sips, early start, shade in the hot hours. ⚠️ Headache, dizziness, stopping sweating, confusion mid-walk = heat stroke: STOP immediately, shade, water, and call rescue if no quick improvement (112) — in isolated mountains, never overestimate your strength.
