Why Don’t We Wake Up From Our Own Snores?

Our sleep expert says our bodies are smart. 
They want to sleep and they want to breathe – so they know not to fully wake us up when we’re doing both.
Different people have different arousal thresholds, which means what wakes up one person won’t wake up someone else. 
Moms with babies know this well.
And if the snorer does wake up from hearing their own snore, they’re not awake long enough to even remember.
