Hot Sauce
Like hot peppers, hot sauce is another food that can keep you up at night. The explanation for this one is a bit different, though: “Hot sauce gets its heat from the compound capsaicin found in chili peppers,” offers Hayim.
“Capsaicin can cause the lower esophageal sphincter to stay open for longer than usual, causing intense feelings of heartburn,” she warns. Sounds like an equation for one spicy mess, if you ask us.
