In a new study by the researchers from Oxford University, data from the DOLAB research project showed that low blood omega-3 levels—particularly DHA (docosahexaenoic acid)—were associated with decreased sleep quality and an increased risk of sleep disorders in children. Upon further study, the researchers found that supplementation with DHA increased sleep quality.
“We have got far less waking during the night. We’ve got more sleeping, and more efficient sleeping as the ratio of time in bed to time asleep is significantly improved,” stated Paul Montgomery, PhD, lead researcher. “These are not small changes. These are substantial changes. I think clinically they are very significant changes too.”
In addition to linking omega-3 levels to sleep quality, they also noted that, “As sleep problems increased, so did behavioral problems,” not surprisingly. “We know that sleep is very important for behavior. It’s been demonstrated in a large number of trials. But what has not been shown [until now] is what fatty acids might have to do with it,” noted Montgomery.
I recently blogged about another of Paul Montgomery’s omega-3 studies in children, and also about how children are not getting enough omega-3 from the diet. Fortunately, it’s easy for children to take an omega-3 supplement to increase their omega-3 levels.
