CO2 is the obvious connection here, but there's another effect at
play. Candles tend to flicker in the 8Hz - 15Hz frequency range due to
turbulence around the flame. This can be quite soporific. It's likely
a neural entrainment. I wonder if LED fake candles that mimic the
flicker have a similar effect. |
