Dos and Don’ts of Eating for Better Sleep

Most people know that eating well can help them feel better and reduce their risk of some serious medical conditions, like diabetes and heart disease. However, what many people don’t know is that their eating habits can also have a significant impact on their sleep quality. It’s not just what people eat either, but how and when they eat as well.

Curious about how to eat better foods for a sleep boost? Below are some simple dos and don’ts of eating for getting some shut-eye.*

Don’t: Eat Lots of Sugar

Does sugar taste amazing? Yes. Can it negatively impact sleep quality? Also yes.[1] While you don’t have to completely eliminate added sugar from your diet, it’s best to limit the amount of sugary drinks and foods you consume. Keep sugar intake to 6-9 teaspoons a day.

Do: Eat Your Fruits & Veggies

Craving something sweet? Grab some fruit; it’s a better choice for getting that sugar fix. Research shows that kiwis, tart cherry juice, and bananas can be particularly great for aiding rest. Vegetables, too, can also help you catch some Z’s. Try green veggies like asparagus and lettuce for some great results.[2,3,4]

Don’t: Eat Right Before Bedtime

Big meals right before bedtime are a no-no when it comes to healthy sleep. There’s no shortage of research that suggests large meals right before trying to sleep can negatively impact your rest.[5] If you really need a bite before bedtime, there’s a better solution than a hearty meal.

Don’t: Skip Breakfast

Some research links consistently skipping breakfast to poor sleep.[6] You don’t have to switch to eating continental platters, though. Just a little something healthy can be enough to help you fuel your body at the start of a new day.

Do: Have Regular Eating Habits

Our body loves routine. While eating the exact same meals at exactly the same time every day isn’t the solution, it is good to have somewhat regular eating habits. Why? Because, according to some research, consistently erratic eating habits is associated with poorer sleep.[7]

Don’t: Eat Empty Carbs All the Time

Simple, empty carbs can be fine every once in a while—but not all the time. Keep the ultra-refined carbs to a minimum.[8]

Do: Eat Whole Grains

Completely cutting carbs out of your diet isn’t the solution for better sleep.[9,10] Instead, opt for whole grains, which are less refined than other types of grains. There’s plenty of research linking whole grains to a host of health benefits, including improved sleep.[11,12]

Don’t: Consume Lots of Saturated Fat & Salt

Saturated fat is one of the “bad” fats that’s best to avoid for plenty of health reasons, including aiding sleep.[13] Likewise, research suggests that salt can negatively impact circadian rhythms, which regulate sleep-wake cycles.[14] Unfortunately, about 9 out of 10 people in the United States eat too much salt on a daily basis. The average sodium intake for adults in the U.S.? About 3,400 mg![15]

Do: Eat Fatty Fish

You need fat in your diet, but it needs to be healthy fat from foods like salmon and avocados. In fact, some research links fatty fish to moderate boosts in sleep.[16]

You’ll also need a little bit of salt in your diet, but not too much. The American Heart Association says that the ideal recommended daily sodium intake should not exceed 1,500 mg.[17] Now, cutting back on the salt could mean less chances of fragmented sleep as well as improved heart health—making this eating habit a priority.

Don’t: Use a Nightcap

This tip might seem a little counterintuitive. After all, most know that alcohol can cause drowsiness. However, just because alcohol can make you sleepy does not mean it will help you sleep well. Why? Because alcohol can suppress restorative REM sleep. That suppression can lead to issues like memory problems, and you’ll also be more likely to experience disrupted rest later in the night.[18]

Do: Cut Off Caffeine 6 Hours Before Bedtime

Most know that caffeine is disruptive to the sleep cycle. What most don’t know is that caffeine can affect the body long after you’ve downed your favorite beverage… which means you need to cut off caffeine early in the day if you want to better protect your sleep. Research suggests that you should quit intaking caffeine at least 6 hours before your planned bedtime.[19]
