New genetic data reveal a two-way link between sleep disorders and chronic obstructive pulmonary disease (COPD). Insomnia more than doubled COPD risk (OR 2.29), while frequent daytime napping raised it by 58% (OR 1.57). Researchers also noted that COPD itself was linked to a higher likelihood of daytime napping. Managing sleep disturbances could aid COPD prevention.

Women with persistently high or rising stress levels later in pregnancy were over three times more likely to experience recurrent preterm birth (rPTB; OR 3.18-3.82). Of 245 women with prior preterm delivery, 22.4% had another preterm birth. Those reporting high perceived stress late in pregnancy faced a 38.9% rPTB rate vs 19.2% in lower-stress peers (aOR 2.44) serving as a strong predictor.
