Whether or not there’s a reduced need or you’re just getting less sleep is a matter of anecdote. I find it entirely plausible that meditators are correct that they need less sleep, but the data you crunched don’t distinguish. To know if you needed less you’d need to have cognitive and health measures.
Technically yes, it reduces sleep duration. My best guess is that this is co-occurring with a reduction in sleep need as well, but I haven’t calculated this—I only started collecting reaction speed data earlier this year. I could check my fitbit data for e.g. heart rate.
Ideally one’d do an RCT, but I have my hands full of those already.
