Title: GigaChill Hand Held Palmar Cooling for Better Endurance and Faster Recovery

United States, 29th Jul 2025 – GigaChill™ unveils a palm‑sized aluminum bottle that turns into a “cold battery” after a short stay in any freezer. Its phase‑change material (PCM) locks itself at 50–60 °F (10–16 °C) — the range scientists call ideal for drawing heat without constricting blood vessels — and holds that temperature for 30–40 minutes.Built on Proven PhysiologyPalms are lined with glabrous skin rich in arteriovenous anastomoses (AVAs), wide vessels positioned just beneath the surface. When cooled in the right temperature window, these AVAs shed heat rapidly; the re‑circulated blood lowers core temperature, trims heart‑rate drift, and delays fatigue.What the Research ShowsEndurance: Step‑test and cycling trials report lower heart rates, cooler tympanic temperatures, and longer time‑to‑exhaustion with palm cooling.Strength: A Stanford bench‑press study recorded a 40% gain in total work over three weeks when athletes cooled their palms between sets.Field Use: Basketball, hockey, and firefighting teams report quicker recovery and clearer focus under heat stress.Simple, Safe, and AffordableIce packs dip too cold, water taps are inconvenient, and vacuum‑pump mitts cost hundreds. GigaChill delivers the same thermal benefit in a passive bottle priced at $29 USD — no batteries, hoses, or mess. Freeze it, grip it between sets or shifts, and rotate a second bottle for extended sessions.At‑a‑GlanceSealed PCM Core: Steady, non‑constrictive coolingAluminum Shell: Fast, even heat transfer and rugged durabilityPassive Operation: No electronics; recharge in any freezer30–40 min Runtime: Ideal for most workouts or heat‑management breaksThe limited‑run MVP is available now at www.gigachill.com. Early customers will receive a discount on the 2026 USB‑rechargeable model.Founded i...
