10 Big Benefits of Eating Pistachios

Pistachios can be a natural sleep aid.

Nuts make good bedfellows! Eating pistachios at night could help you fall asleep faster. The nuts contain ample amounts of melatonin, the hormone that signals to your body that it's time to unwind.

A 2014 analysis found that a 3.5-ounce serving of pistachios contained about 23 milligrams of melatonin—more than the dose found in many synthetic OTC sleep aids. There's also evidence that tree nuts in general can increase serotonin, another hormone involved in relaxation. More research is needed to determine the exact effects of pistachios on sleep, but they may be worth a try as a bedtime snack.
