Scientists reveal causes of daytime sleep attacks

New research links seven blood metabolites to daytime hypersomnia and suggests lifestyle changes, including a Mediterranean diet and reduced fermented foods, as possible options.

Scientists reveal causes of daytime sleep attacks

A new study ties daytime sleepiness to seven circulating molecules tied to metabolism. Excessive daytime sleepiness affects about one in five adults, researchers say, and some people still feel drowsy after a full night's rest. The study points to lifestyle changes, including adopting a Mediterranean-style diet and limiting fermented, aged, and smoked foods as potential tools. Genetics may also influence risk, with earlier work identifying dozens of gene markers linked to hypersomnia, while the new findings focus on blood metabolites.

Experts caution that a test for these markers is not a guaranteed remedy. More research is needed to show direct cause and effect and to translate findings into practical medical advice. If confirmed, the results could help tailor guidance for people with EDS without blaming them for sleepiness.

The piece treats daytime sleepiness as a metabolic signal, not a personal flaw. Tying symptoms to blood markers raises hope for targeted advice but risks oversimplifying without clinical tests proving causation.

The real test is whether these findings translate into affordable, usable guidance for diverse communities. Diet-based strategies must be accessible, and researchers should address equity as they refine recommendations.

The long road from discovery to relief will require careful testing and patient guidance.
