I recently encountered an article on this: meditation, even in non-experienced meditators, appears to improve psychomotor vigilance on following tasks, and experienced meditators appear to sleep less than non-meditators.

Ah, I think I saw that one less. Worth noting that the second study in it, on the long-term meditators, is not controlled/randomized - so it's just correlational. (eg. maybe the less you sleep, the more you can afford the time to do meditation.)

Yep. Not a hugely strong claim, though I'm emailing the author for more information.

Update: The author replied, and doesn't know of any more conclusive studies in this respect.

I've started a multifactorial experiment for the next 360 days; I've decided one of the interventions will be meditation. Randomized on a per-day basis, and if that doesn't show any effect in the analysis, I'll try doing a before-after comparison.
