With Over 25 Years of Experience
As a sleep expert with over 25 years studying thermoregulation and its impact on rest, I've evaluated countless cooling solutions (from fans to those high-end pods) and Flux Sleep stands out for its simplicity and effectiveness.
I've seen firsthand how overheating disrupts sleep cycles, reducing REM and deep sleep stages - essential for cognitive function, immune health, and daily energy. That's why I endorse Flux Sleep: its maintains optimal body temperature without noise or complexity, promoting uninterrupted, restorative sleep with more REM for better memory and learning, deeper slow-wave sleep for physical recovery, and waking up truly refreshed. At a fraction of the cost of premium systems, it's a breakthrough making healthier sleep accessible to everyone.
