Drinking a cup of coffee for breakfast can not only refresh you, but also help promote defecation. Some people who are used to drinking coffee in the morning even find that if they don't drink coffee for breakfast, they will feel poor defecation. Why is this happening?

The American Healthy Living Information Network explained that a cup of coffee contains an average of 40- 180 milligrams of caffeine.

But interestingly, drinking coffee in the morning has a particularly significant laxative effect, and drinking coffee at other times has little effect. Dr Diana marks, an American nursing expert, pointed out that a large amount of caffeine and acidic oil in coffee can enhance the contraction function of digestive tract muscles, and then accelerate bowel movements.

Experts advise not to drink too much coffee. Drinking 1-2 cups of coffee in the morning is helpful for refreshing and relaxing bowels.
