So one of the things we like to say is your body either heals at the rate of a human being, or it heals slower. So there's no such thing as a fast healer. You're just, oh, you're really good at healing at the rate of human physiology, and the rest of us are doing dumb things that are rate limiting our healing. Nutrition, sleep, right? When we are talking about anyone after surgery or injury,

Our benchmark in the line of the sand is eight hours of laying in bed without looking at your phone. That's minimum. And I don't care if you're sleeping because resting is the next best thing, but I can't actually understand inputs and outputs. And let me be super clear.

If you're trying to grow a body, learn a skill, change your body composition, get stronger, heal, that all rhymes with eight hours. We look seven as our minimum. And of course, you're a human being. You're going to get by. I was stressed out last night and wanted to come on to this show with my friend Andrew and do a good job. Like I didn't get great sleep, but I'm a human being.

I'm still going to show up. So what's nice then is we can start to say, okay, what can we control in terms of managing and upregulating, boosting maximal healing rate for humans? And it turns out cold water may not be the best. Icing something might suppress prostaglandin release, right? Which means that you can think of it as you have these circulating stem cells. And again, sorry, everyone.

We get this just very cursory. And we need the chemical signalers from the injured damaged tissue to call those things to be. But if I ice that and suppress that, some of those cells can go swinging on past. There was a great study I saw a million years ago. And it looked at ibuprofen usage in Australian military tactical athletes who had bad ankle sprains.

And those athletes who were given ibuprofen, which does the same thing as ice, suppresses prostaglandin release, right, cuts off some of those chemical signals, were back faster than... than their counterparts who did not have the ibuprofen, but they had chronic ankle instability because they did not have a sufficient healing response because they had shut that healing response down.

So what we find is, look, your body will wait until it warms back up, but if you think you're going to do angiogenesis and make new capillaries and modulate all these things by slapping a non-specific ice pad for a non-specific amount of time over a non-specific tissue, you've got to be kidding me. And so it's really Mickey Mouse. Does ice help for margaritas that are warm? Yes.

Open heart surgery? Yes. Right? Waking you up in the morning. Waking you up in the morning. Hey, I have a kid who needs a placebo. I can numb that thing and give my kids some placebo ice. That's great. Definitely can work for pain control because as soon as you're numb, you can't feel anything. But what's going to happen when you pull that thing off? We're going to come back.
