First, the circulation cycle of food in the digestive system is about 24 hours after entering the human body, that is, from eating the day before to defecating the next morning, the dregs of food digestion and absorption are stored in the large intestine, and finally the anal muscles are stimulated, resulting in a feeling of defecation;

Second, after a day of digestion and absorption, the human body has formed food residues, but at night, the metabolic function of the human body is relatively slow, which is the process of self-repair and removal of toxic waste by various organs of the human body. After another night of deposition, food residues and toxic wastes that need to be excreted are stored in the large intestine and need to be excreted urgently. If you don't defecate at this time, these things will continue to be absorbed in the large intestine, and toxins and the like may be reabsorbed into the blood, which is harmful to the body and urgent for the body.

Therefore, it is very healthy and necessary to defecate in the morning every day, and it will also form the biological clock time of the human body, and then there will be a sense of defecation.

So it's not a good thing to defecate at noon instead. Try not to change like this!
