Jean-Louis and colleagues write, “Black very short-sleepers may be at greater risk of experiencing deleterious physiologic and hormonal effects of insufficient sleep, which may predispose them to adverse cardiometabolic outcomes.”Indeed, numerous studies and sleep curtailment experiments have shown a strong connection between poor sleep, obesity, and cardiovascular conditions.Research indicates that poor sleep disturbs many metabolic pathways, “leading to more insulin resistance, possibly decreased energy expenditure, increased appetite, and immunological changes.”More specifically, zooming in on immunological pathways, several studies have found increased plasma levels of a pro‐inflammatory cytokine called interleukin 6 after partial and total sleep loss.In turn, pro-inflammatory cytokines such as interleukin 6 have been associated with a higher risk of cardiovascular disease and diabetes.So, the sleep deprivation that seems to be more prevalent among Black adults may well account for some chronic conditions — such as high blood pressure, overweight, obesity, and diabetes — to which this group is more predisposed. Jean-Louis and colleagues explain.While the reasons behind these gaps in sleep may be somewhat unclear for now, one thing is certain: Race-related sleep disparities disproportionately affect the Black population in the U.S.Sleep deprivation contributes to further disparities in chronic conditions, by causing more of these illnesses in Black people or by exacerbating them.“When viewed in the context of health equity research, insufficient sleep may be a key factor in understanding diseases that disproportionately burden [Black adults]. Whether sleep time in this population is curtailed by lifestyle choices or restricted by sleep fragmentation, as is the case in sleep apnea, [Black Americans] may be at increased risk of developing chronic diseases (e.g., diabetes and cardiovascular disease) due to insufficient sleep.”– Girardin Jean-Louis et al.In this Special Feature, we question some common misconceptions about sleep, including the role of alcohol, remembering dreams, and late-night cheese.In this Special Feature, we use the latest evidence to examine the neuroscientific underpinnings of sleep and its role in learning and memory…In this Special Feature, we discuss the complex two-way relationship between sleep and mental health conditions, such as depression, anxiety, and PTSD.'Those of us who work in the health disparities space are saddened but not surprised at the race-based disparities that this crisis has brought to…We spoke to six Black women in the United Kingdom and the co-chair of the Royal College of Obstetricians and Gynaecologists' new Race Equality…
