Sleep is finally having its moment.
I'm a sleep researcher and clinician. It's exhilarating to see broader recognition that sleep is important, yet I am often dismayed about the framing of the message — why sleep is said to be valuable.
Messages equating sleep with laziness have long been woven into our cultural consciousness, with aphorisms such as "I'll sleep when I'm dead" and "The early bird gets the worm" reflecting our fears that sleep is a hindrance to success and accomplishments.
We find inspiration in legends of historical figures such as Leonardo da Vinci, whose fantastic achievements supposedly required only a modicum of sleep. These messages characterize sleep as an impediment to productivity.
It is encouraging that we are increasingly turning away from that mistaken mind-set and recognizing the importance of sleep. However, in our emerging embrace of sleep, the end goal often remains productivity. The shift is only that sleep is now seen as a facilitator of productivity rather than an impediment.
Sleep does often increase productivity — as a byproduct of its many benefits, including increased energy, focus and mental processing speed. However, we do ourselves a disservice to focus so heavily on productivity as the reason for prioritizing sleep — especially as it is often narrowly defined by career and financial success.
In a culture that assigns positive moral value to productivity, linking sleep with productivity means that sleep is no longer morally neutral, but is good only so long as it serves the purpose of increasing productivity. This obscures the many other reasons to prioritize sleep as an essential component of health. It also stigmatizes groups affected by sleep disparities and certain chronic sleep disorders.
We now know that sleep is connected with every aspect of human health including cardiovascular function, pain, mood and the immune system. Sleep is a pillar of health but has long been neglected in comparison to its more popular cousins — diet and exercise.
