The effects of sleep debt
Several years ago I spent some time in a lab studying sleep in fruit flies.They've put out a number of interesting publications since my time there.[1] Evidence of very large variability in sleep duration between flies, with limited consequences for very long duration sleep deprivation (wrt lethality)[2] Evidence of context-dependent modulation of the effects of sleep deprivation. It appears the effects of sleep deprivation on males can be affected by sexual arousal/activity.It makes me wonder if there are similar effects on humans. A night spent socialising too late does effect one differently to one spent working too late.[1] https://www.science.org/doi/10.1126/sciadv.aau9253[2] https://elifesciences.org/articles/27445
