5 Foods That Are Making You Sleepy

There's a reason bananas are often presented as a fix for muscle cramps: They're high in magnesium, a mineral that helps relax muscle cells. "We give people magnesium at night to help them sleep," says Blake-Gumbs. Another magnesium source? Nuts, particularly almonds, cashews and peanuts. The dosage that'll make someone tired is different for everyone, but you're more likely to feel the effects if you're too low on magnesium to start with.

Pick Yourself Up: As long as you're not deficient in magnesium, you should be fine to eat either bananas or nuts on their own. Symptoms of a magnesium deficiency (according to the most recent National Health And Nutrition Survey that examined magnesium intake, nearly half of all Americans aren't meeting recommended levels) include loss of appetite, nausea and fatigue, and those with type 2 diabetes, gastrointestinal disorders or celiac disease are at particularly high risk.
