Sleep Better

Have you been struggling to fall asleep lately? There always comes the time when we can’t seem to get enough of sleep. Bearing in mind that good night’s rest is crucial for our health and wellbeing, it’s important to make lifestyle modifications that aid in avoiding sleep deprivation.

You’ve probably come across all sorts of tips and tricks that help you sleep better, but the latest study revealed an unexpected type of food can help you make much-needed changes and finally get enough of rest at night.

What Food To Eat For Better Sleep?

Chamomile tea and warm milk are effective in helping you get some sleep, but there’s a lot more you can do to wake up well-rested in the morning. The latest study made a discovery that will surprise you for sure. You see, scientists discovered that eating more fish can be helpful for people who want to sleep better.

Professors Jianghong Liu and Adrian Raine at the University of Pennsylvania carried out an interesting study with their team of researchers. The inspiration for the study stems from the fact that fish intake is linked to improved cognition among children, but underlying mechanisms are unknown.

Better sleep could be a factor in a relationship between fish and cognition. That’s why they conducted a study whose primary objective was to assess whether greater fish consumption is associated with fewer sleep disturbances and higher IQ scores.

The study involved 541 Chinese children whose fish consumption and sleep quality were evaluated when they were 9 and 11 years old. When children turned 12, scientists measured their IQ too.

Results were published in the Scientific Reports[1] and they showed that both higher IQ scores and fewer sleep problems correlated strongly with frequent consumption of fish.

Sleep And Cognition-Fish Relationship

The link between higher IQ and fish consumption was firmly associated with the frequency at which children ate it. For example, children who always eat fish and those who sometimes consumed it had a higher IQ score than kids who never or rarely ate fish.

Interestingly, the quality of sleep partially contributed to the ability of fish to enhance one’s cognitive skills. As you can already assume, beneficial effects of fish on cognition come down to a high level of Omega-3 fatty acids. While sleep did play a role it benefited verbal, not performance IQ.

Importance of this study is massive; this is the first research to demonstrate that frequent fish consumption can decrease sleep problems and improve quality of good night’s rest. As a result, it exhibits beneficial effects on cognitive skills and IQ.

How Much Fish To Consume?

It’s easy to assume that one, especially a child, has to consume tons of wish in order to sleep better or enhance cognitive skills. Not entirely correct! Scientists explain[2] that our diet should be well-balanced, meaning it’s recommended to consume a variety of nutrients and foods, including fish.

Even if you eat fish once a week you’re still making a progress, especially if you don’t have a habit to consume fish and seafood in the first place. Start small to build a momentum and you can increase consumption to a few days a week.
