In our largely sleep-deprived society, quantifying the consequences of sleep loss on emotion is crucial for selling psychological well being.

Industries and sectors susceptible to sleep loss, reminiscent of first responders, pilots and truck drivers, ought to develop and undertake insurance policies that prioritize sleep to mitigate towards the dangers to daytime operate and well-being.”
