A blurb that’s just coming out into the press.

Slow wave activity (SWA), a stable trait dependent marker of the intensity of non-rapid eye movement (NREM) sleep, is lower in young healthy African-Americans compared to Caucasians who were matched for age, gender and body weight, according to recent research.

Electrical brain waves predict attentional deficits following sleep deprivation

Sleep disorders are highly prevalent among police officers

Sleep deprivation can lead to increased smoking and drinking
