Generally, are there and how long do lingering affects of polar sleep patterns affect someone? For example, assume someone slept for 2 hours one day and then slept for 14 hours the next. Their 2 day average would be 8, an unofficial heuristic for optimal sleep length. However, intuitively, I feel that their cognition would notably be different for a while because of these polarized events. Is this true? And if so, what are the basis for this, and how long do these effects last assuming someone got 8 hours a sleep religiously over the next few weeks?
By changes in their cognition (the ones I feel "intuitively"), I mean like a lower fidelity of memory, slower reaction times, but still the ability to function normally in a group setting.
