on our circadian clocks

How our body’s circadian clocks affect our health beyond sleep . One excerpt:
Our intestines, our stomach, and our gut have circadian rhythms, too. Late at night, just like our brain goes to sleep, our stomach and gut start to shut down. Our intestines and gut don’t move food down the digestive tract, so if you eat late at night, the food just sits there. At the same time, the stomach has a buildup and starts to produce acid.
During the daytime, the circadian rhythm in our mouths actually produces saliva that neutralizes that acid. But in the evening, even our mouths shut down, which is why we don’t salivate much in our sleep. When you have a lot of acid, food isn’t going down, and acid is coming to our mouths, we get acid reflux. It’s a very simple thing, but just eating early in alignment with the gut rhythm can help. 
Another idea is in terms of exercise. Exercise has many benefits for the circadian clock and sleep cycle. So for example, taking a short walk in the morning has as huge impact on synchronizing the brain clock and improving arousal and alertness.”
