A new study–unpublished to date, I should add–is getting loads of attention today. Using various NIH survey data from the mid-1990s, researchers at Columbia University determined that teens allowed to stay up past midnight experienced a 42 percent greater likelihood of depression than kids whose parents required a 10 p.m. bedtime and experienced a 30 percent higher incidence of suicidal thoughts. That’s an interesting finding, but the study remains unpublished and it is based on data from 15 years ago, which makes me somewhat dubious of its power.

What I found most interesting is that the late-bedtime teens slept 7 hours 30 minutes a night compared with 8 hours 10 minutes for the earlier-bedtime group. I find it difficult to believe that 40 minutes of sleep could make that much difference, but maybe it can.
