Summary

In this episode, Dr. Tommy Wood returns to Barbell Shrugged for part two of a deep conversation on brain health, cognitive decline, and the daily habits that shape long-term mental performance. Joined by Doug Larson, Travis Mash, and Dr. Mike Lane, Tommy unpacks why oral health matters far more than most people realize, explaining how gum disease, oral bacteria, and chronic inflammation may contribute not only to cardiovascular disease but also to dementia risk. The crew also digs into the importance of sensory input, from hearing and vision to social interaction, and how losing those inputs over time can quietly accelerate cognitive decline.

The conversation then shifts into sleep, where Tommy breaks down what actually matters most for protecting the brain. Rather than obsessing over perfect sleep scores or chasing an arbitrary eight-hour target, he argues that the biggest levers are sleep opportunity, regularity, and avoiding behaviors that wreck sleep architecture. The group explores the different roles of REM and deep sleep, how sleep supports emotional processing, learning, and metabolic cleanup in the brain, and why wearables can be useful for trends without being trusted too literally. They also cover naps, alcohol, caffeine, common sleep aids, magnesium, chamomile, and why worrying too much about sleep can itself become part of the problem.

Finally, the episode broadens into brain risk and brain resilience in the modern world. Tommy highlights major risk factors for cognitive decline including hearing loss, high blood pressure, diabetes, smoking, obesity, alcohol, air pollution, and toxic exposures like lead and other environmental contaminants. He also gives a nuanced take on technology, arguing that video games, digital tools, and even AI can be either brain-supportive or brain-eroding depending on how they are used. When technology expands your capabilities, it can sharpen cognition. When it replaces thinking entirely, it can weaken the very skills you are trying to preserve. This episode is a practical roadmap for anyone who wants to think more clearly, age better, and protect their brain with smarter everyday decisions.

Shrug family, Doug Warson here, and today on Barbell Strugged, we got Dr. Tommy Wood back on the show for part two of high-performance brain health.

0:07.4

You probably heard me say this. Every time we interview Tommy, I tell him he's one of my favorite guests because he is a super interesting guy, and I always learned a ton when I talk to him. I have a very strong interest personally in brain health and performance and don't want to be a person that gets Alzheimer's or dementia ever, but certainly not early in life like I have seen. It's a painful thing to watch, and it would certainly be a painful thing to go through, and I want no part of it. So, Tommy's back on the show. We talk about a bunch of interesting things. We talk about oral health and dementia. We talk about why hearing loss and social isolation can contribute to cognitive decline. Talk about sleep and what it really does for memory, recovery, and emotional regulation.

0:40.9

Then we also dig into a very important question around to what degree technology and

0:45.4

AI are impacting our brain, which seems to be a big concern right now from people in the world.

0:50.7

So if you are interested in cognitive performance, clear thinking, you want to minimize

0:54.6

cognitive decline and be healthy mentally as you age. This episode is for you. Enjoy the show.

Welcome to Barbell Shrug. I'm Doug Larson here with Coach Travis Mash and Dr. Michael Lane and

1:06.5

Dr. Tommy Wood back for part two, brother. We were on her about a month ago and we covered many things related to brain health,

1:12.6

but we got to the end of the show and we were like, man, we have so much left to talk about.

1:16.6

We also met over the weekend in Vegas, finally, after many years.

1:19.6

Yeah, it was great to finally hang out, and I'm excited to be back.

1:25.6

Yeah, hell yeah, brother. We covered many things nutrition and many things training.

1:31.3

I really want to dig in. We got sleep, we got stress.

1:35.3

We have a handful of other topics. What other topics do we not cover on the first show that you want to touch on here?

1:41.3

Yeah, I think there's a few other things that are worth thinking about.

1:47.0

So, obviously, I've got this new book coming out.

1:52.0

A lot of the kind of the ideas that how we use our brains determines how they function.

1:57.0

So we can say to talk more about what actually stimulates the brain, how we interact with technology, but also think about, yeah, sleep, stress, other risk factors for cognitive function, cognitive decline, like air pollution, like microplastics are having a moment, uh dental and oral health super important um like

2:21.1

oh i would like to know more about that the dental like that's you know fascinating that your teeth

2:27.0

are so i mean obviously they're important but that's like an inflammation issue with people that don't floss

2:31.9

and that type of thing yeah yeah so that's essentially what it looks like. There have been a couple of things that the poor all health have been tied to.

2:40.0

So dementia risk, but also cardiovascular disease risk and maybe those two things are linked because we know that heart health and vascular health directly affects the brain.
