Higher Omega-3 Levels Associated With Longer Sleep Duration
Approximately 35% of American adults get less than 7 hours of sleep per night, which is considered insufficient sleep. A recent study has found that higher serum omega-3 fatty acids levels may be associated with healthy sleep duration.
Participants in the study included 1,314 adults over the age of 19. They completed sleep questionnaires used to evaluate sleep duration. Blood serum levels of omega-3 fatty acids were measured.
Participants with normal sleep duration (7-9 hours) had higher omega-3 fatty acid serum levels compared to those with short sleep (5-6 hours) and very short sleep (less than 5 hours) duration. Participants with very short sleep duration had particularly low levels of EPA, DHA.
The study was conducted by researchers from the University of British Columbia. It was published online ahead of print on February 10, 2022 in the journal Sleep Health.
In a previous study, saffron extract was found to help improve sleep quality.
