About
I’m Alex Warenstein, a 48-year-old sleep biohacker and the creator of NighttimeComfort.com. I dedicate nearly all of my free time to researching better sleep. I test sleep technology, supplements, breathing devices, and recovery tools using real-world data from EEG, oxygen monitors, CGMs, and sleep sensors. I’m not a doctor or a product seller. I’m an independent user who buys products with my own money, studies the research, and shares honest findings—including what does not work. My goal is simple: turn complicated sleep science into practical information that ordinary people can actually use.
