Another important reason why you may want to avoid eating late is due to the effect it can have on your sleep cycle. Research has found that the digestive process can have serious implications on your sleep cycle, causing you to wake up more often, and have a harder time falling asleep in the first place. One of the worst foods that you can eat if you have a hard time falling asleep at night are sugary foods such as cookies and other baked goods. In contrast, chamomile tea or warm milk may actually help you fall asleep at night.
