To maintain proper sleep habits, some foods and beverages must be avoided. Meals that are greasy, hot, or heavy can make it difficult to go to sleep. Drinks with added sugar or caffeine, as well as excessive alcohol consumption, can disrupt sleep. Eat a small, healthy dinner a few hours before bed, stay away from sugary and caffeinated beverages, and moderate alcohol consumption to encourage better sleep. Avoid eating a lot of food right before night, especially if it has a lot of sugar, spice, or fat.
