5. Fatty fish

Tuna, salmon, mackerel, and trout are super-healthy fatty fish. Most notably, they are recognized as superfoods due to their high amounts of sunshine vitamin (D). Almost 85 grams of salmon provides 71% of your daily vitamin D needs. But, of course, that’s not the only superpower salmon has.

In a large study, those who ate around 300 grams of salmon accumulated in a week for half a year, managed to fall asleep 10 minutes faster than those who consumed beef, pork, or chicken.

Researchers concluded that the vitamin D content found in salmon was responsible for the result of this effect. So, the higher levels of vitamin D you have, the better the sleep.

However, it seems that vitamin D is not the only one good at shutting your eyelids. The omega-3 fatty acids found in salmon are known for minimizing inflammation in the body. On top of that, they also prevent heart disease and enhance brain health.

To sum things up, eating some salmon (or any fatty fish) just before bedtime, will most likely help you get a deeper sleep.
