College students often struggle to get healthy rest, but how does their happiness connect to their nightly sleep? Researchers studied whether being satisfied with life relates to better sleep habits across college students in the United States. They looked at national survey answers comparing satisfied students to dissatisfied students across several sleep measures. They tracked getting the recommended seven or more hours of rest, having few insomnia symptomsTrouble falling asleep, staying asleep, or waking up too early., and getting restorative sleep, meaning sleep that leaves you feeling refreshed. The researchers found that students who were satisfied with life were much more likely to report all three positive sleep habits. Furthermore, this positive link between life satisfaction and favorable sleep held true regardless of a student's age, sex, race, or ethnicity.
You are a coach trying to see if players who practice more score more goals. You track practice time and goals, and you find a strong link, but you can't tell if practice causes goals or good players practice more. In this paper, researchers found a strong link between life satisfaction and sleep health, but they can't say which causes which.
College students often struggle with sleep and mental health. This study shows that life satisfaction is strongly linked to good sleep, suggesting that improving one may help the other. The link holds across age, sex, race, and ethnicity, meaning it applies broadly.
The abstract doesn't say. It only reports the association and that there was no evidence of variation by demographics.
