When you feel sick, you prefer to sit still. This behavior pattern is not only well known, it even has a name: “inflammatory-induced sickness behavior.”
In the modern world this easily leads to a particularly pernicious vicious cycle. Modern lifestyles lead to metabolic syndrome. Metabolic syndrome produces systemic inflammation, which makes you feel like sitting still. Wanting to sit still makes what would otherwise be the most potent tool for reducing systemic inflammation—exercise—tough to bring to bear.
This rather dense article from back in 2010 describes the problem: Inflammatory modulation of exercise salience: using hormesis to return to a healthy lifestyle. It also proposes a category of solutions: hormesis. That is to say, any of a set of mild metabolic stresses that prompt a response greater than “just enough” to stave off the damage produced by the stress itself.
The result is less systemic inflammation, and therefore less inflammatory-induced sickness behavior, hence an increased inclination to move.
Or, as they say:
We therefore propose that exercise salience, the motivation to undertake physical activity, is modulated by the inflammatory status of an animal, decreasing in an inflammatory phenotype, including the metabolic syndrome and increasing in an anti-inflammatory “healthy” phenotype. The type of phenotype may well be determined by the degree of hormesis, as metabolic stressors, such as exercise, plant polyphenols and calorie restriction tend to induce an anti-inflammatory phenotype.
Besides exercise, the article suggests two other broad categories of available hormetins.
One is related to food, and consists of the obvious stuff that everybody knows: Avoid industrially produced edible substances. Consider such modalities as time-restricted eating, calorie restriction, or fasting. Include foods rich in plant polyphenols. (In other words, “Eat food, not too much, mostly plants.”)
The other is related to temperature: Expose yourself to mild cold and/or heat stress. (Spend time outdoors in the winter. Take a cold shower. Spend time outdoors in the summer. Take a sauna.)
Each of these things will produce some mild metabolic stress. As long as you don’t overdo it, that mild stress will produce a stress response greater than necessary to handle the stress itself, with the side-effect of bringing down systemic inflammation. With the systemic inflammation eased, you’ll start feeling like moving again. That puts the potent tool of exercise back on the table.
Nature has a more recent article on all this stuff, which is sadly behind a paywall.
Among the things that I pay more attention to than I ought is a vast swath of preliminary research (and guesses based on preliminary research) about how large physical things (like diet and exercise) work at the scale of cellular biology.
To work though an example:

Great advice on the right way to handle fall risk for seniors. Includes an excellent video.
Elliott Royce takes practice falls at least five times every morning. He doesn’t just practice; he preaches, too. He goes to assisted living centers, senior centers and community centers to talk about how to prevent serious injuries if you take a tumble.
For my fall-semester OLLI class I took “Ballet for Adult Beginners,” taught by Lei Shanbhag.
I took the class as enrichment of my movement practice. I felt like adding something very different to my existing range of taiji, running, natural movement, a tiny bit of parkour, and so on, and I thought that ballet would be very different, and yet still fall within the broad spectrum of “movement practice.”
I also took it as cultural enrichment. I wanted to learn a bit of the vocabulary of ballet—both the literal vocabulary (Allongé, Battement, Ronds de jambes), and the movement vocabulary (learning to see a dance as a conversation between the dancers and one another, and with the audience).
As far as enhancing my movement practice, I’d have to say it wasn’t a complete success—I did the moves in class, but I didn’t really learn them.
That’s entirely a matter of my own abilities: I’m just very slow to learn movement stuff. I have crappy mirror neurons, and I can only learn movement stuff verbally—I have to watch the movement, describe it to myself in words, and memorize the verbal description. Only then can I attempt to do the movement, by playing back my memorized description and attempting to execute it.
As perhaps you can imagine, this is not the quick and easy way to learn to dance. The upshot is that I need to go more slowly than most people (so I have time to create the verbal description), do it more times than most people (so I have time to memorize my verbal description), and then do it yet more times (so I can learn to execute the moves that I’ve described).
I could probably have learned, let’s say, half or a third of what was taught, if we’d done just that much, and spent two or three times as long on each thing.
As it was, I enjoyed the moving very well, but didn’t leave each class with one or two specific things I might practice between then and the next class.
I don’t mean this in any way as a criticism of the class, which was enjoyable and informative. I had the sense that other people in the class (all with some sort of dance background) were picking up much more of the movements than I was. And Lei was constantly asking if the amount done was the right amount. I could have said, “Wait! Before we go on, let’s do this one thing 5 more times.” I chose not to, so that’s all on me.
Despite not learning the movements, I nevertheless did the movements (as best I could), so the classes were a nice workout—well structured, with a warmup, stretching, practice of the moves we were learning, and more stretching.
I was more successful at learning the cultural stuff. I didn’t learn every ballet term, but I learned enough to provide some useful context. Now I can look things up and understand them. I also began to learn to see ballet, which is something that I didn’t really appreciate before.
One tidbit that we learned the first day stuck with me: The posture of ballet dance—feet turned out, hips forward, weight forward—dates back to Louis XIV. Basically, turning your feet out lets you activate your glutes, while shifting your weight forward lets you activate your quads. If you’ve got good musculature in your legs, this posture lets you show that off. (Especially if, as Louis often was, you’re wearing tights.)

Basically, ballet dancers stand that way because Louis XIV thought standing that way made his butt look good.

Perhaps because I’ve reached an age where I might be considered a senior my own self, I’m becoming increasingly annoyed by the way public health advisors infantilize seniors.
It’s most obvious with fall risk, where “don’t fall” not only is repeated constantly, it almost always comes with a particular sort of blame-the-victim advice—remove tripping hazards, wear supportive shoes, be careful on wet or icy surfaces, always use your assistive devices (canes, walkers, etc.)—the implication being that if you fall it’s your fault for not having made your environment sufficiently fall-proof.
This advice is not merely useless or insulting; it is actively harmful.
It’s harmful first of all because it conflates “senior” with “frail” in a way that will inevitably lead the public to harass seniors just like the public feels free to harass fat people, smokers, pregnant women (especially those with the temerity to drink alcohol), or anyone who isn’t conforming with whatever the current public health fashion is.
Inevitably too, it will have that effect in the minds of seniors who will start to think of themselves as frail simply because everybody says so.
More to the point, it’s is precisely backwards for what you want if your goal is (as I think it should be) to prevent frailty.
This is perhaps not as harmful as the infantalization of children and youth, which works extra harm because adults have more power to impose their conditions on children, whereas seniors mostly have enough autonomy to ignore inappropriate advice. But it hurts seniors in exactly the same way it hurts children, reducing their ability to become or remain robust actors in the wide world.
Now, I don’t want to fall into reverse-blaming the victim. If you are frail, then taking steps to reduce the risk of injury just makes good sense. My go-to activities to prevent frailty might well put an already frail person at serious risk.

I try to resist the urge to suggest to seniors that they should do hazardous activities in the name of preventing frailty. But the advice I see from professionals (and random strangers) goes too far in the other direction. Following it is going to doom already frail people to becoming steadily more frail.
Great run! My sore foot didn’t hurt until I was just a few steps from home. My knee didn’t hurt at all. My heart rate held exactly where I wanted it.

After the Rattlesnake Master 10k I came down with either a very nasty cold or else a moderately nasty case of the flu. Whatever virus it was, it had me pretty much down for the count for a solid week. Today was the first day in almost two weeks I felt up to a run.
