# Does night-sleep-deprivation have any effect on cognitive performance?

(Asked by: username_0 on 2017-08-03)

Sleeping during the day might lead e.g. to vitamin D deficiency. But I am interested in what effects might night-sleep-deprivation have on cognitive faculties.

Does sleeping during the day and absolutely not getting night sleep have an effect on working memory, long-term memory, intelligence level, processing speed, etc.?
