You can sleep 2 hours after a meal, because most of the food is digested and absorbed more than 2 hours after a meal, and the burden on the gastrointestinal tract is not heavy at this time to sleep, and the blood supply to the brain and heart is also sufficient, so sleeping at this time will not affect the quality of the patient’s sleep. If the patient lies down to sleep immediately after eating, it will easily cause reflux of food in the stomach. The burden on the gastrointestinal tract is also heavier at this time of sleep, and without activity, food digestion will also be slow, which will affect the patient’s sleep and also easily lead to insufficient blood supply to the patient’s heart and brain, leading to the aggravation of cardiovascular disease. Therefore, it is recommended to sleep at least 2 hours after eating. After eating, you can do more light physical activities, which can promote the digestion and absorption of food in the stomach into the intestines.
