Omega-3 Fatty Acids May Help Support Sleep Quality
Sleep is as important for good health as diet and exercise. It affects growth and stress hormones, the immune system, appetite, breathing, blood pressure, and cardiovascular health. A new report suggests that omega-3 fatty acids may provide sleep quality benefits.
The researchers enrolled 66 healthy adults over the age of 45. Half received six 480 mg capsules of omega-3 fatty acids that contained 576 mg of DHA and 284 mg of EPA daily for 12 weeks. The other half received a placebo.
The Oguri‐Shirakawa‐Azumi sleep inventory MA version was used to evaluate sleep quality at baseline and at the end of the study period. A sleep state test was administered for 7 days before the beginning of the study and 7 days at the end of the study period.
Sleep efficiency scores were significantly higher in the omega-3 group compared to the placebo group. Frequent dreaming scores were also significantly higher. Previous research has suggested that frequent dreaming may help alleviate stress.
The study was conducted by researchers from the Yokohama University of Pharmacy. It was published on October 5, 2002 in the journal Nutrients.
Lemon verbena was found to help improve sleep quality in a previous study.
