A candle flame has five distinct zones, each burning at a different temperature, from the coolest region near the wick at 600 degrees Celsius to the hottest outer veil at 1,400 degrees. This is just one of many precise details in this episode of I Can't Sleep, which traces the candle from its prehistoric origins to its modern role as a decorative object. The central argument is that the candle—once a necessity for illumination—has been transformed by technology into something we use primarily for atmosphere, scent, and symbolism, yet its basic physics and chemistry have remained remarkably consistent for millennia.

Show Notes
Candles are simple objects with a surprisingly long history of being useful, decorative, and occasionally dramatic. In this episode, we explore how candles work, what they’re made from, and why people kept improving them long after better lighting came along. It’s a practical little tour through wax, wicks, combustion, and the oddly persistent charm of setting a tiny fire on purpose. It’s steady and consistent, with no whispering and no sudden changes, just enough to give your mind something to follow as you wind down. Happy sleeping!
