sleeping at night

When I'm sleeping with my boyfriend, he snores extremely loud and I sometimes talk in my sleep. But recently when someone snores extremely loud it wakes me up out my sleep and I'm wide awake. So what I do is turn on the air/fan/ open a window. So the air from outside can help him breathe better. Which that normally works, but I wanted to know are their other tricks to helping someone lower their snoring or help with their sleeping habit.
