Mouth taping (stopped snoring immediately), magnesium glycinate before bed, no screens an hour before sleep, keeping the room cold, not eating dinner so late and regular sauna sessions. Individually they helped.

Together they made a real difference, loud cars and city noise don't wake me up anymore.

I know it sounds like biohacker stuff, but it works. This tool makes it possible to actually find the root cause instead of just guessing. Love it!
