I can anecdotally confirm and at the same time fail to confirm these findings. Since recently I am awoken about 1—2 times per night. Yet, the noise is only disturbing enough to awake me in between my sleep cycles. I have not noticed any mood changes. However after my son was born I definitely noticed a considerable drop in mood due to being awoken randomly at night. (It was also roughly 1—2 times a night) I wonder if the stage of the sleep cycle—one is experiencing—would influence the mood changes.
