Physical activity could mitigate the mortality risks associated with a short sleep duration (less than 6 hours per night).

This advice is based on robust epidemiological data, notably a large observational study published in the European Journal of Preventive Cardiology (2021). This research followed more than 92,000 adults over several years and effectively showed that the protective effect of exercise reduces the risk of all-cause mortality among short sleepers. It is important to note that this is an observational study: it shows a correlation, but does not prove a direct cause-and-effect relationship. Exercise does not biologically replace sleep, which remains crucial for cerebral and metabolic recovery. The term "mitigate" is used appropriately by the creator here, as movement does not totally eliminate the risks linked to chronic sleep deprivation. This is an important nuance: exercise improves the body's resilience, but does not make a lack of sleep harmless.
