Sleep debt and naive hope for the weekend: why two days do not always save a week of sleep deprivation

When sleep deprivation accumulates, it is not only built into fatigue. Attention, irritability, the ability to restrain impulses, appetite, and the sensitivity of the reaction to stress change. A person begins to live as if in a slightly worse version of himself and gradually gets used to it as a background. That is why sleep debt is dangerous not only in volume, but in addiction. We cease to clearly feel how far we have moved from a normally restored state.

Weekends can really help, but not in the most optimistic way. If the weekly regime differs greatly between weekdays and Saturday-Sunday, the body also falls into an additional time shift. You seem to save a little exhaustion, but at the same time you lose the rhythm again. On Monday, the body receives a double blow: both under-recovery and a new return to someone else's schedule.

This does not mean that sleeping longer on the day off is bad. The problem starts when the weekend becomes the only survival mechanism instead of the main logic of the week. The body is better able to withstand not heroic compensations, but a relatively predictable rhythm, in which it does not have to pick itself up from the wreckage every week.

In this sense, talking about sleep debt does not sound like a reproach, but a reminder of the limit. Man is not an infinite system capable of lending recovery without interest. Sleep comes sooner or later. And the earlier you recognize it, the less chance there is of building the whole week on an illusion that works worse than it promises.
