How to reduce DB Reads?

I just noticed that I hit the 500k db reads limit on my very small next js app with the most data being present in one collection having around 50 documents.

I do use a lot of relations to link the collections. When creating a relation to another collection, I usually do a 2 way relationship. Is this the root cause?

Or could it be something like infinite loops on the app, calling the database?

Any suggestions on how to diagnose and fix?
