An underrated medicine

被低估的一味药

Of all 'exercise', walking is probably the most underrated. It's too ordinary, too effortless, too unlike 'a workout' — so many people feel it doesn't count. But if there were an intervention that markedly lowers all-cause mortality, that almost anyone can do, and that can be sustained for decades, its name is very likely 'walk a little more each day'.

This island does two things: makes the real dose of walking clear (not the mythologised '10,000 steps'), and connects to the existing 10k-steps debunk — the latter gets a dedicated animation in the HIIT-vs-steady story, so here we only cover the positive: how much you actually need, and how to walk so it's worth more.

First correct a common misunderstanding. Current physical-activity guidelines (HHS 2018) recommend adults accumulate about 150 minutes of moderate activity per week; and from the 2018 edition, they removed the old 'must be at least 10 minutes at a time to count' threshold — meaning the extra blocks you walk commuting, the flights of stairs you climb, the round trips to the shops all count toward your activity. The barrier to walking is far lower than you think.
