The Good Type Of Stress: Hormesis

Hi, Doctors Pharmacy listeners. It's Dr. Mark here. If you've been following me, you know that I'm obsessed with understanding the latest research on longevity and how we can apply it to our daily lives. So I wrote a book about it. Think of it as a roadmap to Optimal Aging. It's called Young Forever, and it comes out February 21st, 2023. It's never too early or too late to take control of your health.

And this book will show you how.

Whether it's through restricting your food intake or time restricted eating or exercise or hot and cold therapies or hypoxia or hyperbaric oxygen, you literally activate these ancient systems of healing repair, including DNA repair, dramatically reducing inflammation and boosting your body's antioxidant systems and boosting stem cell production, increasing your brain function.

Hey, everyone, it's Dr. Mark. One of the most important tools I have for helping my patients optimize their health is testing.

And that is why I love what.

Rupa Health is doing. Functional medicine testing can require placing orders with lots of different labs, and it can kind of get really complicated for doctors and their patients to easily access results and keep track of everything. But Rupa Health has totally streamlined that process, looking at hormones, organic acids, nutrient levels, inflammatory factors, gut bacteria, and so many other internal variables can help us find the most effective path to health and healing. I'm really excited about that now and I can finally take advantage of these tests without the hassle of the confusion of going through so many multiple labs. Rupa Health is the place for functional medicine practitioners to access more than 2,000 specialty lab tests from over 20 labs like Dutch, vibrant America, Genova, Great Plains and more. It's 90% faster, letting you simplify the process of getting you the functional tests that you need and giving you more time to focus on your patients. This is really a much needed option in the functional medicine space and it means better service for you and your patients. You can check it out with a free live demo with a Q&A or create an account at rupahealth.com that's R-U-P-A-Health.com People are always surprised when I tell them that even with a whole foods diet rich in plants, we can still be nutrient deficient and addressing nutrient deficiencies is one of the lowest hanging fruits for optimizing our health and feeling better at any age. And that is why I'm a huge fan of AG1 from Athletic Greens. Since our soils are so damaged, the plants can't extract the nutrients because there's no living matter anymore. And we're up against issues like chronic stress and toxicity and sleep deprivation like never before. And our bodies need some extra help getting all the right information to work properly. Now, that information comes in the form of vitamins and minerals and phytonutrients. and good bacteria, all of which help ourselves remember how to efficiently tackle their important jobs.

So one of the things I use.

Every day to support my diet is AG1 from Athletic Greens. With just one scoop of AG1, I get 75 high quality vitamins, minerals, whole food source superfoods, probiotics, adaptogens and more to support my entire body. Even with a really healthy diet, it's hard to hit the mark for all our nutrient needs, so I feel better knowing I have some extra help from AG1. Unlike other supplements and powders out there, AG1 is third party tested and made without GMO, nasty chemicals or artificial anything. It actually tastes great, kind of like a tropical green drink. I like it on its own mixed with water, but it also works really well in most smoothies. If you're curious about trying AG1 from Athletic Greens for yourself, right now they're offering my community 10 free travel packs with your first purchase. All you have to do is visit athleticgreens.com, / Hyman. Again, that's athleticgreens.com/Hyman to take ownership over your health and pick up the ultimate daily nutritional insurance. Now let's get back to this week's episode of the Doctor's Pharmacy.

Hey everybody, it's Dr. Hyman. Welcome to the Doctor's Pharmacy, a place for conversations that matter. And today we're going to talk about why stress is important for healthy aging. Yes, stress. And this is a special episode of the Doctor's Pharmacy called Health Bites, which can improve your health by taking small steps every day and lead to profound changes over time. And today's episode is all about the benefits of stress. Yep, you heard me right, stress, which can be a good thing. But the type I'm talking about is not what you're thinking about. It's called hormesis. It's not a psychological stress, which can be bad for you. It's a physical stress. And the these stresses are really important. And basically the idea is that what doesn't kill you makes you stronger. And it's actually true. Our bodies are not designed to be in a 68 degree, thermoregulated, perfectly controlled environment. Our bodies evolved in a very dynamic state where there was scarcity of food, where we had to do a lot of exercise, where we had extremes of temperature. And so I, I, altitude. So we really have developed these ancient mechanisms to activate our healing systems using the power of stress, which what I want to talk to you about today. So think of it like these small little doses of adversity that help activate these ancient longevity pathways in your body. For example, starvation. You know, we all had to deal with starvation because there was no grocery stores or Whole Foods or 7-Eleven's on every corner. And we would literally go through periods of scarcity. And when that happens, our bodies would kick in these ancient mechanisms to keep us alive. So that's a stress, for example. So this is a very protective thing. And when your body has these kinds of stresses, it activates these ancient healing systems. So when you activate, whether it's through restricting your food intake or time restricted eating or exercise or hot and cold therapies or hypoxia, or we'll talk about other ones like hyperbaric oxygen, you literally activate these ancient systems of healing and repair, including DNA repair, dramatically reducing inflammation and turning off inflammation, boosting your body's antioxidant systems, boosting stem cell production, increasing your brain function, because if you're starving, you want to make sure you have enough brain power to go find some food. It improves your protein function, enhances your detox systems, stimulates your mitochondria, improves your insulin sensitivity, and improves your gene expression. All these things are involved in helping you live a longer, healthier life. And I really talk a lot about these from the framework of longevity. and it's because my book, Young Forever, is coming out in February 21st, 2023, where I lay all this out in very detailed ways. This is just a little teaser to get you a sense of what's in the book. And I really, I'm really excited about the hormesis thing, and I try to do it every day because it's, it's such a really exciting and Powerful way to often, at very low cost, activate these ancient healing systems. So let's talk about what are the most common ways that we have access to that we can all use to regulate this? The first is calorie restriction. Now, that sounds like a terrible idea because who wants to basically not eat, right? We like eating. It's a good thing. But the idea is don't eat all the time. In last week's Health Bite, I talked about how fasting or time-restricted eating or calorie restriction activates these longevity switches to clean up and repair the body through what we call autophagy. which means self-cleaning or self-cannibalism that helps repair DNA, shut off inflammation, improve insulin sensitivity, makes our mitochondria. There's so many beneficial things. And you don't have to starve yourself forever, right? You just need to do a short period of not eating every day, which we used to call breakfast, right? We eat dinner and then you eat breakfast, but we just kind of eat all the time. And we don't often Give ourselves enough time before we go to bed to not eat, and we often eat early in the morning. So the idea is to give yourself at least 12 hours every day. Like if you eat dinner at six, then you can eat breakfast at six. Or if you eat dinner better to eat dinner at six and then breakfast at eight. That's a 14 hour fast. Now that's not hard. Everybody can do that. And it has profound impact on our biology rather than eating all the time. So it really is powerful because if you look at the calorie restriction model, It extends life by a third in animal models. So, it's very few things that can do that. I'm not saying that having a 14 hours between dinner and breakfast will extend your life by a third, but it helps this process of autophagy or cleaning up your cells and it improves your insulin sensitivity, helps reverse diabetes, cools off inflammation, helps you mobilize fat, improves your mitochondrial function, helps you build muscle, lowers fat mass, and boosts stem cell production. It's pretty much awesome. And so the holy grail of longevity science and healthy aging science is to somehow hack calorie restriction, right? But nobody wants to eat a third less calories because you're gonna be miserable, cranky, and skinny and it's gonna be bad. So you wanna do things that mimic that. And so basically by taking a 12, 14 hour, 16 hour break a day, you can activate these longevity switches, things like insulin signaling, mTOR, Sirtuins, AMPK that we talked about last time on the podcast, but it's not too hard. I would encourage you to do that. There are also other things, phytochemicals, potentially drugs that can do this too, but let's just sort of talk about the food. The next thing is heat therapy, saunas, powerful strategy has been used in cultures. I love that the Finns have a lot of saunas in Finland. There's enough saunas for everybody to be in a sauna at the same time in Finland and the entire population. And the control group in a study they did was like someone who took a sauna once a week versus two or three times or four or five times. Those people who took saunas four to six times a week, reduce their risk of death by 42%, which is pretty impressive. And what happens when you take a sauna? Well, it activates something called heat shock proteins, which help to refold and fix damaged proteins. One of the hallmarks of aging are these damaged proteins. So it helps fix those, recycle them. It also activates antioxidant systems, helps to also activate your innate immune system, improves your cardiovascular fitness, heart rate variability, insulin sensitivity, blood sugar, blood pressure, all these incredible benefits from just sitting in a sauna. So I love that because you just sit there and you don't have to do anything. It's great. And you can incorporate those through a hot bath, through a sauna, an infrared sauna, steam, hot springs, hot yoga is my favorite thing to do. So there's a lot of ways you can actually do this, but it's important to do on a regular basis. Next is cold therapy, which often is great following heat therapy. Cold therapy again is also powerful because our bodies have mechanisms of actually activating really important things that keep us young longer by this trigger of a cold temperature. So, you know, you might have heard of Wim Hof and the Iceman. And, I mean, that's extreme going in an ice, a tub full of ice. I've done that a bunch of times. I do a little bit warmer, like 40 degrees, not like 32 degrees, but it, it 45 degrees sometimes. That, that can be a very powerful tool for healing. your body from pain and injury, but also it boosts endorphins. It strengthens your immune system and activates brown fat, which is your metabolic engine. It improves circulation and helps reset your autonomic nervous system. So really, really beneficial for you. So I'd encourage you to do cold water swimming, cold showers. You can just do a cold shower in the morning. I do that regularly. I'll just go in the shower. Better than coffees. Jump in the morning, go in an ice cold shower for two minutes, hit your timer on your phone or watch and just boom, you're already doing cold therapy. Super easy. And of course, there's cryotherapy where you go into a whole unit that's like minus 200 and something degrees Fahrenheit. And that's also very, very helpful, but it's hard to get one of those. So just start with a cold shower or even a cold bath after a steamer sauna. Exercise also a really important way to do hormesis because you're pushing yourself, right? So exercise is a really important form of hormesis, basically whether it's interval training, whether it's strength training, they all have different, different benefits. But when you, when you lift weights, for example, you tear muscles. It's an injury. But your mind goes, oh, I better do something so it builds more and you get bigger, stronger muscles. So make sure you get good cardiovascular Fitness through interval training. That's basically where you Sprint and then rest, Sprint and rest. And I did that this morning on my Peloton. I also did a strength training with bands. I did resistance training, also did a steam in my steam shower and also ice bath right after. So, I did all kinds of hormesis. I did like four kinds of hormesis in an hour in my morning routine. It was pretty easy. You know, you obviously have to have a little steam shower, but those aren't too expensive to put in. I've had mine for 20 years and it's never broken, so it's pretty good. And then, and then doing all those things can really be powerful in terms of the strength training stuff. You don't have to lift the massive amounts of weights, but bands are great. I do those. You can, you know, do bodyweight exercises. There's lots of things you can do that are pretty low cost. Also interval training, whether it's sprints or whether it's yoga, sorry, vigorous running or vigorous walking or riding your bike, tennis. I played tennis recently with somebody. I was running, sprinting the whole time. My average heart rate was 145. that's average the entire time I was off at 160 or more. So it, it's good. Also, you know, we can increase muscle mass and function by, by doing these bands, weight lifting, body resistance training, as I mentioned. And, you know, I, I kind of was resistant to it, no pun intended, for a long time because I still like smelly gyms. But now I do it at home. I use bands. It's great. And it's super powerful hormetic therapy. Exercise is probably the the Fountain of Youth, if you could put exercise in a pill, it would be the most powerful longevity drug on the planet. It works a lot on all the hallmarks of aging we talked about last week. So, encourage you to get moving, get lifting, do that stuff. There's lots more things I talked about in terms of hormesis in the book, like hypoxia therapy, like hyperbaric oxygen therapy, ozone therapy. There's a lot of things that you can do, but those are really easy and accessible that we just mentioned. So, I encourage you to check out my new book, Young Forever. It's out February 21st. Go to youngforeverbook.com. you get all kinds of bonuses and access to health and wellness products that I tend to use and recommend free. It's awesome. Basically, the whole idea of this podcast was to inspire you to find ways to stress yourself in a good way, basically to understand the principle of what doesn't kill you makes you stronger and do intentional stress small bouts, not too much, right? Too much cold therapy, you're gonna freeze to death, too much heat therapy, you'll dive, heat stroke, et cetera, et cetera. Too much calorie restriction, you're diastasis. So it's finding that Goldilocks amount and they'll jumpstart your body into a rejuvenated state and keep you living a longer, healthier life.
