Over religious roommate

I 21M a student at UG has this roommate who constantly prays all the time. I am not opposed to him praying but why does it have to be when I'm sleeping at dawn.

I've spoken to him about how it inconveniences me but he says he'll lower his voice when he prays and it doesn't change. Mind you it has been going on for a year and still he has not changed. I tried telling him to do it outside but he's scared of the dark(like wtf?) so he can't. I wake up with body pains and headaches almost every few days.

I wrote to the hall tutor's office to change my room and they said they couldn't but others had their room changed. This is my last year and I don't want to go through this again.

I don't even know what to do again
