DDL against the objects the procedures depend on is usually the reason. Playing overenthusiastically with GRANT/REVOKE can also be a (less common) reason. Anything susceptible of modifying the execution plan can also be a culprit. Check what your procedures depend on (DBA_DEPENDENCIES) and check the modification date for these objects in DBA_OBJECTS may give you a clue. Otherwise it may come from maintenance operations (I am not too sure about it, but I wouldn't be shocked if collecting statistics would invalidate procedures to force them to recompile on the fly and take advantage of new stats. It wasn't the case some versions ago but I *think* it has changed).
