Intermural Hockey safety

so i just recently joined an inturmaural team for hockey at sru. and i am really excited for it to begin. Until i found out that you don't need to wear a helmet, which kind of scares me alittle. I think i will probably wear my shin pads so that i do not get whacked with a hockey stick in the shins, which by the way really hurts. Well i hope it is as fun as eveyone makes it out to be.
