Ergonomics doesn’t fix the worker; it fits the workstation to them. The same idea, applied to physiology: don’t override the system, design the conditions around it so it can do what it’s built to do.
This is the discipline that ties the rest together. Once you’ve read the wiring, somato-ergonomics is what you do with the reading — the deliberate shaping of work, space, and day to fit the body running them.
Fit, not force
Performance that comes from forcing a system against its grain is expensive and fragile. Performance that comes from fitting the conditions to the system is durable. The whole discipline turns on choosing the second over the first.
The environment is a variable, not a backdrop
Noise, light, interruption, company, fuel — these aren’t preferences, they’re inputs that measurably change how a nervous system performs. Treating them as designable is what separates ergonomics from advice.
Design beats discipline
Most recurring friction isn’t a character flaw; it’s an un-designed condition. Re-cast as a design problem, it becomes solvable without shame — which is both more honest and more effective than trying to out-will the same situation again.
