> “finds that less sleep than time-in-bed doesn't seem to affect them much” The abstract of the article doesnt say this. It finds that the intervention managed to increase their average sleep length by 27 minute from 5.5 hours to ~6 hours. Thats still way bellow the recommended length. It also finds that this intervention didn’t improve their work performance. This might be because “less sleep doesnt seem to affect them much”, but it might equally well be that it affects them tremendously and the 27 extra minutes were not enough to help them.
