New research about, “Sleep duration and mortality – Does weekend sleep matter”1, was recently published in the Journal of Sleep Research.
Broadly, this study suggests that we can develop sleep deficits and we can somehow restore or replenish sleep deficits over the weekend. This finding conflicts with a basic tenet of sleep hygiene protocols, having a consistent sleep routine.
When two theories conflict, finding the middle ground may be best – For example, sleeping excessively over the weekends may be more disruptive than helpful to your overall sleep health, but I personally wouldn’t complain about a little more sleep on the weekends when possible.
While this study adds new information to consider in sleep research it also validates a common theme seen in almost all sleep related research, the need for sleep and its effects on health.
What happens during sleep? Why is it restorative or perhaps a better word is, regenerative, in-light-of the finding that “catch-up sleep” may have an impact on longevity? To be continued….
