I love to exercise. I could do it all day long. I have often walked 3-4 hours a day when the air quality is good ... and thats the problem. Many people, myself included, live in areas where the AQI leaves me wondering if I'm actually harming myself by being outside and exercising. Right now the Airnow AQI for Denver, PM 2.5 is yellow (Unusually sensitive people should consider reducing prolonged or heavy exertion). I think that includes people that exercise, so I won't walk. But these mathematical models leave me wondering about their accuracy, how many sensors were used, are they accurate at this exact moment, etc. I wish there was better information at our disposal where we could make better decisions on when a dosage of exercise is worth it given a certain AQI (PM2.5, PM2.10, Ozone, etc).

  Maybe I’m misreading something in the tone, but when unusually sensitive people should consider maybe changing their planned a activities a little bit what does that mean for the average healthy person? It kind of sounds like a non-warning. I mean what’s prolonged exertion anyway? A marathon? 10 hours of physical labor like construction? A light jog in the park? And what is “reduce”? Stop completely? Switch from marathon to half marathon? Work a 5 hour construction shift instead of 10? Somehow I don’t think physical laborers are reducing their workload for this.

A study that says that exercise cures this or that seems to come out every week, but the fact remains remains that convincing people to do it is the hard part. To quote Ann from Parks and Rec: "Jogging is the worst, Chris. I mean, I know it keeps you healthy, but God, at what cost?" The only thing I can say is start with as only much as you're comfortable with and no more, and pat yourself on the back for doing it. Building the habit is so much more important than making progress in the beginning.

  I don't get what system in our brain causes so much resistance to new obviously rewarding habits. Sometimes it's so hard, to get started. It's indeed a huge step to begin a schedule. That said I also found that there's a step where I'm motivated just to see if I can reach a goal. Say 5km jogging. And when I reached it, I may try a new goal, but very often I suddenly lose most desire and pleasure. Before that, every mile felt like a victory nearby. Now it's meh. I guess it's necessary to account for such "plateau" and wave around a goal for a while, then have a stretch up period, then loop.

    >I don't get what system in our brain causes so much resistance to new obviously rewarding habits. Easy. Before agriculture, calories were hard to come by. If you ran around for no good reason, that meant you wouldn't have enough energy to catch whatever animal was nearby when you needed food and you'd die. Death by hunger was a much more real threat than death by sedentary lifestyle when evolution was wiring all our circuits up.

      It doesn't necessary have to do with calories. Even, say, reading, or learning.

I won't go into details about what I think - but two books that have helped me understand and deal with the symptoms (and possibly helped me help others) are: Do the Work - Steven Pressfield The Now Habit - Neil Fiore

This is a Mayo Clinic commentary on a publication in Neurology: http://n.neurology.org/content/early/2017/12/27/WNL.0000000000004826 http://n.neurology.org/content/early/2017/12/27/WNL.00000000... in which a group of physicians "systematically reviewed MCI prevalence, prognosis, and treatment." The recommendations specifically apply to Mild Cognitive Impairment, which is a pre-Alzheimer's like condition where cognitive function has declined significantly from age-norms or recent history, but not enough to interfere with activities of daily living (and so does not meet the diagnostic criteria for Alzheimer's/dementia). What's interesting about the review is that for the first time, two interventions are suggested: physical exercise (as mentioned in the headline), and cognitive training. Pharmaceuticals for Alzheimer's are commonly prescribed for MCI; but this review specifically notes that no high quality evidence exists for their efficacy in MCI.
