That part in particular is as simple as... you get higher because you're laying down, so there's no vertical pressure on your back.

- kenjackson 5y agoNot the nightly half-inch, but like your growth from 18" to 6' over the course of your life happens while you sleep.
- wombatmobile 5y agoHow would you measure 8 hours of that?
- forgotmypw17 5y agoI 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.
- wombatmobile 5y agoIf 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?
- forgotmypw17 5y agoThat may be the average, but it happens in spurts, and you can probably get some decent measurements if you put your mind to it.
- slver 5y agoAh yeah, growth occurs mostly during sleep. Vast majority of it. Growth hormone is actually released mostly during sleep. When a cell has to function as part of a higher-level system, "dividing" is kind of disruptive. So this happens while we sleep.
