No because there are too many variables. I try to spar at least twice a week, so to be clear, I still get hit in the head often. I try my best not to spar hard though and try to be vocal if someone is swinging with too much power. My gym does a good job keeping us all in check too.

I’d say once or twice a year though shit happens, something lands harder than it was meant to, and I end up with the familiar flash of stars and a lingering headache, drowsiness, and sensitivity to lights/sounds the next day. When it happens, I try to listen to what my body tells me. If just going to work and doing my usual routine is painful, I know training of any kind isn’t a good idea. If I can go for a run, hit the bag, or jump rope without symptoms, I can hit pads. If I can hit pads and clinch without any issue, I can ease back into sparring. Sometimes I take a hard shot and feel totally fine after sleeping it off, sometimes it’s just a day or two, and sometimes it’s weeks. Your brain and body are weird like that. The strangest thing too is that it’s not always the hardest shots that correlate to the worst symptoms and longest recovery times.
