#2"Could" is an interesting choice of word. I know researchers are cautious but that wording makes it meaningless.

Quite. "5 minutes of exercise a day could raise blood pressure" is equally accurate.

Somewhat related is Betteridge's law of headlines:
> Any headline that ends in a question mark can be answered by the word no. It is based on the assumption that if the publishers were confident that the answer was yes, they would have presented it as an assertion; by presenting it as a question, they are not accountable for whether it is correct or not.
I like to swap out any of these maybe-headlines with the exact opposite. It may help us, or it may not.

From the article:
> Just five minutes of activity a day was estimated to potentially reduce blood pressure, while replacing sedentary behaviours with 20-27 minutes of exercise per day, including uphill walking, stair-climbing, running and cycling, was also estimated to lead to a clinically meaningful reduction in blood pressure.
Sounds like 5 minutes of exercise is where it has a statistically significant measurable impact in blood pressure, but 20-27 minutes is where it's a meaningful impact.

The headline is about a study that showed increased activity was correlated with decreases in blood pressure.
So, no, it's not equally accurate to say the opposite is "equally accurate" unless we're playing pedantic games where we ignore the study and pretend it's all just meaningless words.

#6some people just have a bad genetic soup and do exercise and diet and such and still have hbp well beyond the numbers designated as meaning "high" ultra high etc I didn't see any hard numbers of reduction in the article either, I've read that smoking raises bp by 5-10points which is largely marginal when you look at how inaccurate most bp readings are. I'm skeptical in this selling environment we live in that this isn't all just to sell drugs to people for their whole lives, these are the same people who want to decimate human populations btw

#7How much more evidence do we need, that exercise is good and any amount is better than none?

Getting a little beyond the headline, we find they had people wear blood pressure monitors and accelerometers and concluded:
> More time spent exercising or sleeping, relative to other behaviors, was associated with lower BP. An additional 5 minutes of exercise-like activity was associated with estimated reductions of –0.68 mm Hg (95% CI, –0.15, –1.21) SBP and –0.54 mm Hg (95% CI, –0.19, 0.89) DBP. Clinically meaningful improvements in SBP and DBP were estimated after 20 to 27 minutes and 10 to 15 minutes of reallocation of time in other behaviors into additional exercise. [1]

5-10 points isn't marginal just because there is measurement variance to account for. And just because there's variance doesn't mean you can't fuzz out real numbers. It's like thinking you can stop a timing attack with sleep(random()).
I'd be very skeptical of defending something like high blood pressure. People do the same with high cholesterol. It's a bunch of cope and wishful thinking that they're very different from everyone else who gets heart disease, our #1 killer.

#10Tabata et al.[1] found in the mid-1990s that just 2-4 minutes of "high-intensity intermittent training may improve both anaerobic and aerobic energy supplying systems significantly." This was popularized as "Tabata training" 20+ years ago. I generally believe that brief bouts of exercise can be very beneficial, especially because they're easier to do consistently over the long-term vs. more time-consuming routines. For a decade now, I've just been running through my neighborhood most days for 20-30 minutes (with some sprints mixed in) and doing one or two maximal sets of pushups or pullups or barbell exercises at home on a weekly basis. I know a lot of people who got really into longer (e.g. 60-90 minute) gym routines but couldn't sustain it for more than a few months, and then stopped doing anything.
