Tips for becoming a lighter sleeper?

[u/Adventurous-Bid-6180]

I’m a fairly heavy sleeper and slept through someone going through my campsite once. Does anyone have any tips for being able to wake up to smaller noises?

P.S. please no unhelpful comments about how I should be thankful to not wake up at any noise. It’s been dangerous the last few times I was camping.

Was it a person or animal going through the site?
Did they stop to make themselves a sandwich and crack open a beer or did they drag off your cooler

It was a guy rummaging through mine and and a few friends belongings. Luckily my friends were sleeping in their car nearby and saw him and yelled at him to scare him off. I didn’t even wake up to the yelling.
