Why don’t we get woken by our own snoring?
Asked by: Joel Edwards, Bradford
Your ears still receive while you sleep, but your brain filters out low-priority sounds – you’re more likely to wake if you hear your own name than a random word, for example. Especially loud snores can wake up a snorer, but only partially, and they’ll usually go right back to sleep almost immediately.
Brainwave research suggests that even non-snorers have 20 to 25 of these ‘microarousals’ per hour that they don’t remember in the morning.
