Story summary

Researchers at Brigham and Women's Hospital identified seven blood molecules associated with excessive daytime sleepiness (EDS).
The study indicates that diet and hormones play significant roles in EDS, with omega-3 and omega-6 fatty acids potentially alleviating drowsiness.
Data from 6,000 participants in the Hispanic Community Health Study assessed sleepiness through surveys and blood samples.
Tyramine, present in fermented foods, correlated with increased daytime sleepiness and reduced sleep quality.
EDS impacts up to one-third of US adults, raising risks for heart disease and obesity.
