Swiss chard contains over 9 mg of potassium per one cooked cup (125 g). Beyond having more potassium than a banana, Swiss chard also provides antioxidants, iron, zinc, and magnesium, which can help reduce stress, making it easier to fall into a deep sleep.

Potassium is a vital mineral for cardiovascular health, muscles, brain, and kidneys. A medium-sized banana contains 422 milligrams (mg) of potassium. This mineral helps maintain electrolyte balance, relaxing muscles to prevent spasms and cramps that disrupt sleep. Potassium also regulates the autonomic nervous system, stabilizing heart rate and reducing symptoms of sleep disorders.

While bananas are a well-known source, several other foods offer even higher potassium levels, contributing to improved sleep quality:

Avocado: One avocado contains 975 mg of potassium, providing about one-third of the daily value (DV) for adults. Avocados also offer healthy fats and other nutrients such as magnesium, folic acid, and fiber. Regular consumption can reduce inflammation, stabilize bowel movements, and promote the release of sleep-inducing hormones, according to Eating Well.

Pumpkin contains about 564 mg of potassium in one cooked cup. You can mash pumpkin as a side dish, or use it in soups, pasta, or baked goods to boost your intake of potassium, vitamin A, and vitamin E. Drinking pumpkin milk in the evening enhances magnesium and potassium levels, promoting mental relaxation and aiding sleep.

Guava is rich in vitamin C, an anti-inflammatory antioxidant that can help prevent and manage chronic inflammatory conditions. One medium-sized guava has nearly 700 mg of potassium, contributing to better sleep quality.

Sweet potato: A medium-sized sweet potato provides nearly 860 mg of potassium, promoting effective relaxation. Sweet potatoes are rich in fiber, vitamins A and C, zinc, and potassium, benefiting gut health and digestion. According to WebMD, they also contain high levels of beta-carotene, which is good for general health and sleep. The high carb content of sweet potatoes supplies essential energy, preventing hunger and waking up in the middle of the night.
