Insomnia is a serious problem for a lot of people. It is frustrating, leaves you exhausted, affects your quality of life and even contributes to increased risk of disease. What if just getting more of one simple mineral could help?
The typical modern diet is way too high in sodium and way too low in potassium. Low potassium has been associated with shorter sleeps and poor sleep quality. This new study examined the relationship between eating patterns of potassium and sleep.
The study, which included 4,568 people, found that higher intake of potassium at dinner is significantly associated with better scores on the Athens Insomnia Scale.
There are several reasons why potassium might help you sleep. Potassium is needed for muscle relaxation, facilitating sleep. It is also essential for neurotransmitter function. Potassium also lowers blood pressure, including nighttime blood pressure, and people with nocturnal high blood pressure suffer more sleep disturbances.
This study offers insomniacs hope by suggesting the simple strategy of getting more potassium at dinner.
The best way to increase dietary potassium is to increase fruits, vegetables, whole grains and legumes. Of course, potassium is also available as a supplement.
