How would you measure 8 hours of that?

• forgotmypw17 5y ago
  I think the basic answer to that is: by measuring height before and after, controlling for laying down still but not sleeping, perhaps also with some intermediate measurements.

    If most of human height growth occurs in the first 20 years of life, that's about 200 microns per 24 hours. Can you measure that accurately? What sort of fluctuating errors would be introduced by for example, temperature and hydration?

      That may be the average, but it happens in spurts, and you can probably get some decent measurements if you put your mind to it.
