I don’t have any literature on it, but it has had that effect on me. That is, as long as I’m meditating regularly (I average about 45 minutes a day of “serious” meditation, and another 60 minutes or so of “casual” meditation) I find if I don’t get a full 10 hours I still often won’t have sleep attacks (in fact I now normally only sleep about 8 hours most nights) and I can sleep as little as 6 hours and still function mostly normally (but not doing that repeatedly, and I will almost certain have a sleep attack on those days).
