According to a 2014 National Sleep Foundation Poll, many kids in the United States are not getting a sufficient amount of sleep each night—which the National Institutes of Health say should be around 10 hours nightly for school-age children. But what if helping our little ones catch more shuteye were as simple as adding a daily fish oil supplement to their diet?

A recent study out of Oxford University examined the effects of Omega-3 DHA supplementation (600 mg daily) on more than 350 children ages 7 to 9, about 40 percent of whom suffered from regular sleep disturbances. Results of the 16-week study, slated to be published in an upcoming Journal of Sleep Research, revealed that the kids who received the Omega-3s as opposed to a placebo slept about an hour longer each night and had fewer waking episodes. Professor Paul Montgomery, lead author of the study, believes he knows why.

“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,” said Montgomery. “For example, lower ratios of DHA have been linked with lower levels of melatonin, and that would fit with our finding that sleep problems are greater in children with lower levels of DHA in their blood.”

DHA, or docosahexaenoic acid, is a beneficial Omega-3 fatty acid found abundantly in cold-water fish such as salmon and tuna. In previous studies DHA has been linked to better sleep quality in children, as well as improvements in thinking and behavior. However, because getting children to each fish can sometimes be a challenge for parents, supplementation is often a beneficial alternative.

Says co-investigator Dr. Alex Richardson, “…this randomized controlled trial does suggest that children’s sleep can be improved by DHA supplements and indicates yet another benefit of higher levels of Omega-3 in the diet.”

Last week new guidelines for the treatment of cholesterol were published in the New England Journal of Medicine online. Though the guidelines were released in 2013 by the American College of Cardiology and the American Heart Association, researchers are just now beginning to look at what their impact would be on Americans—and the data is raising some concerns.

A team of analysts led by Michael J. Pencina, Ph.D. of the Duke Clinical Research Institute in North Carolina now estimates that nearly 13 million more U.S. adults may soon be taking statins to treat high cholesterol and prevent heart disease. Here is a quick (and eye-opening) breakdown of the numbers, based on information gathered from more than 3,700 U.S. adults between the ages of 40 and 75:

  • The new guidelines could result in 49 percent of U.S. adults ages 4075 being recommended for statin therapy, an increase from 38 percent.
  • The increase is much more pronounced among adults free of cardiovascular disease who are over age 60, with 77 percent recommended for statin use under the new guidelines vs. 48 percent under the previous standards. This contrasts with a modest increase from 27 percent to 30 percent among U.S. adults between the ages of 40 and 60.
  • Those most affected by the new recommendations are older men who are not on statins and do not have cardiovascular disease. Under the earlier guidelines, about 30.4 percent of this group of men between the ages of 60 and 75 were recommended for statin use. With the new guidelines, 87.4 percent of these men would be candidates for the therapy. Similarly for healthy women in this age group, those recommended for preventive statin use are projected to rise from 21.2 percent to 53.6 percent.i

The new guidelines focus more on risk factors such as smoking and obesity rather than specifically working to lower so-called “bad” cholesterol, but statins are not the only answer. Although beneficial for people who have already had a heart attack or stroke because they help reduce plaque buildup in the blood vessels, the cholesterol-lowering drugs have health risks that should not be ignored—and heart disease prevention should begin instead with important diet and lifestyle changes.

Simple changes such as getting more exercise, optimizing your Omega-3 intake, and eating a diet high in non-starchy vegetables, low-sugar fruits, healthy fats, lean proteins, nuts and seeds can go a long way toward improving your heart health now and in the future.

In response to the new guidelines, cardiologist Rita Redberg of the University of California-San Francisco said, “If our goal is to help people feel better, live longer and have less heart disease, putting millions more on statins is not going to do that.” She emphasized instead the importance of a healthy diet, exercise, and quitting smoking.
