Discussing a paper co-authored with David Birks, Alexandre Erler suggests sleeping less can provide a greater opportunity for well-being.
While many people today are not sleeping long enough, there is still an important minority of the population who sleeps longer than average. Even a small reduction in the number of hours a person sleeps could have a significant positive impact on how well that person's life can go. The authors propose that there is a strong reason to investigate any ways of allowing people, particularly long sleepers, to function on less sleep without harming their health or quality of life.
