Why can your body sleep through alarms even when using multiple alarms to help wake you up?

544 views

I usually set up about 6 alarms or more to help me wake up in the morning because I’ve had numerous occasions of not waking up at the first alarm or second. I’ve noticed times where it’s never the same alarm that wakes me up, it usually changes so I know all the alarms are working (volume all the way up and has some kind of annoying sound/ringtone. I’ve also had to change the sounds to it when it’s reaching the later alarms because I somehow manage to start ignoring it.

Long answer short the human brain is amazing. It can filter out sounds and smells that we get used to. Like if you live in a part of town that has intermittent loud sounds your brain will eventually filter it out so you don’t notice it.

I lived in a building that was by some LRT (light rail train tracks) and within two weeks i didn’t even notice them. My brain determined that the sound was unimportant when i was in my apartment and as such didn’t tell me about it.
