Sleepless nights

The argument

In the middle of the coronavirus pandemic, multitudes of people have experienced increased insomnia or trouble sleeping. Sleep is critical to our health and happiness, and disrupting it has consequences that reach well beyond feeling tired. The cognitive effects of sleeplessness include irritability and difficulty focusing. Health problems such as cardiovascular disease and diabetes can also be influenced by a lack of sleep, and insomnia intensifies mental health issues — which is what makes it a psychological finding rather than merely a medical one, since the people most likely to lose sleep during the pandemic were often those already under the greatest strain. The mechanism runs through stress. Insomnia or difficulty sleeping is triggered by stress or by a change in the quality of life, when the body's fight or flight response partially activates and holds a person in an alerted state. That response is not designed to be sustained; it is meant to resolve when the threat does. A pandemic offers no such resolution, because the threat is indefinite and largely outside any individual's control. The COVID-19 outbreak increased many people's stress and decreased their quality of life, and high rates of sleeplessness followed. The conditions of quarantine added a second, more mundane pathway to the same result. Measures in place worldwide led to less time outdoors and less sunlight, and to the readjusting of sleep schedules and alarms as the fixed points of the day — commutes, school runs, office hours — disappeared. Both of the things that ordinarily anchor a sleep pattern were removed at once, and the reserve people might have drawn on to cope with the disruption was itself being depleted by it, which is how a population-wide event turns into a population-wide loss of sleep.

Premises

Counter-arguments

Sleep problems could easily be influenced by other things than the coronavirus pandemic. More time and people at home could disrupt patterns, not working could lead to more energy, and a multitude of other causes could be to blame. Because it is so popular in the media, people assume their resting is thrown off by coronavirus, but it is actually another cause being misidentified.

Rejecting the premises

[Rejecting P1] The premise runs together two claims: that sleep loss became more common, which is offered without any measurement, and that sleep loss is harmful, which nobody disputes. The cardiovascular and metabolic harms listed belong to sustained clinical insomnia and are imported to describe a period of disrupted sleep. [Rejecting P2] A plausible pathway is not evidence that it operated. The counter names alternatives the premise does not exclude — changed household routines, no commute, later and looser schedules — and the argument's own causes, less daylight and shifting alarms, are effects of a changed daily structure rather than of stress. The conclusion also overreaches: disrupted sleep would evidence strain, not the broader claim about mental health that the position asserts.
