How to avoid getting arm hair in food?

Sorry if this question is slightly gross.

I happen to have a significant amount of hair on my arms and the back of my hands. When preparing food using my hands (e.g. kneading dough), sometimes hair gets in the food. How can I avoid this? What would a serious / professional cook do?

Would they wear gloves and long sleeves? Would they shave their arms? Are there other approaches?
