Need sleep advice for split shifts (4AM–8AM & 4PM–8PM)

Hey everyone! I’m looking for advice from anyone who’s dealt with split shifts or irregular work hours.

I work two shifts every day — one from 4:00 to 8:00 in the morning, and another from 4:00 to 8:00 in the evening — and I’m really struggling to figure out the best way to get quality sleep around this schedule. Any tips??
