Up to your risk tolerance. With the discovery of CTE we know that repeated minor head trauma still causes long-term problems. IMO it's too easy to overdo it especially once the blood gets pumping. I've gone to more BJJ classes than I can count thinking "ah I have a few injuries, I'll just roll light" and then it turns into repeated deathmatches.
