You already know drinking coffee late in the day can keep you up. But you’ll be surprised at these sneaky sleep disruptors.

If you’re one of the millions of Americans who struggle with sleep, you’ve likely tried all the most-talked-about remedies. Maybe there’s chamomile tea in your pantry and melatonin supplements in your bathroom cabinet.

You already know it’s not a good idea to consume caffeine in the late afternoon and that even though that glass of wine may help you initially drift off to sleep, you’re going to wake up in the middle of the night regretting it.

Still struggling? You could be unknowingly consuming something that’s to blame. According to sleep doctors, there are more foods and drinks that can mess with sleep than people realize.

Rounded up here are seven foods and drinks that sleep doctors recommend steering clear of if you struggle with sleep. Plus, they offer guidance on which foods will work for you, not against you.

7 Foods And Drinks That Surprisingly Can Cause Sleep Problems

1. Spicy foods

Digging into some hot chicken wings or curry at dinner could cause sleep problems when you head to bed. Dr. Abhinav Singh, a board-certified sleep medicine and internal medicine doctor, is medical director of the Indiana Sleep Center and a medical reviewer for Sleep Foundation.

He told that eating food that’s spicer than you’re used to can increase acidity in the stomach, which can cause acid reflux that can make sleeping difficult. Singh explained that gastric acid is already naturally higher at night, and if it continues to rise, it can disrupt sleep.

Dr. Ruchir P. Patel, a sleep medicine doctor and medical director of The Insomnia and Sleep Institute of Arizona, agreed. “Eating spicy food close to going to bed can cause acid reflux, which can trigger the brain to wake up excessively.”

In addition to triggering acid reflux, Singh said, spicy food can make people feel hotter, which can also disrupt sleep.

2. Pizza (or anything with tomato sauce)

Patel said many people don’t realize that tomato sauce can be an acid reflux trigger, which can disrupt sleep similarly to the effect of spicy food. That means having pizza or spaghetti for dinner could keep you up.

In general, Patel said, it’s best to avoid eating food that’s high in sodium and saturated fat (like pizza, especially if it has pepperoni) three hours before bed because it takes longer to digest, which can then cause sleep problems.

3. Burgers

Like greasy pizza, burgers are another food that takes the body longer to digest. For this reason, Singh said, eating a big, juicy burger too close to bedtime could keep you up, especially if it has ketchup on it, which, again, can trigger sleep-disrupting acid reflux.

If you want a burger that will help with sleep rather than disrupt it, choose a plant-based burger made with lentils, which Singh said are easier to digest, or, if you are going to have beef, go for as lean a cut as possible.
