Higher levels of omega-3 DHA in diet improves sleep, reveals a new study.
The randomized placebo-controlled study by the University of Oxford found that children on a course of daily supplements of omega-3 had nearly one hour more sleep and seven fewer waking episodes per night, as compared with the children taking the corn or soybean placebo.
AdvertisementAccording to the study, it found that there is possible links between sleep and fatty acid status in healthy children, and that higher blood levels of the long-chain omega-3 DHA are significantly associated with better sleep, including less bedtime resistance, parasomnias and total sleep disturbance.
It was also revealed that higher ratios of DHA in relation to the long-chain omega-6 fatty acid AA (arachidonic acid) are also associated with fewer sleep problems.
Professor Paul Montgomery of Oxford University said that various substances made within the body from omega-3 and omega-6 fatty acids have long been known to play key roles in the regulation of sleep and lower ratios of DHA have earlier been linked with lower levels of melatonin.
The study is published in the Journal of Sleep Research.
