There is no specific standard for how long it takes to go to sleep after eating a full meal, and this time is related to many factors, such as personal eating habits, postprandial activities, and personal digestive speed, and so on. 1. First of all, since different foods take different amounts of time to digest, it usually takes longer to digest foods that are high in protein and fat. Therefore, if you have a greasy diet, such as large fish, meat, desserts, etc., you should sleep 4 hours after eating, and if you have a light diet, usually about 2 hours will be enough. 2. Secondly, the speed of digestion of food is also related to whether or not the movement after meals, after meals, people with a greater amount of movement on the consumption of food will be more. Therefore, people who exercise after eating, such as walking and yoga, can usually go to bed earlier than those who are sedentary after meals. 3. Again, individual digestion speeds vary, and those with faster digestion will have shorter intervals between bedtimes. The exact time varies from person to person. Therefore, how long after eating enough to sleep needs to be analyzed on a case-by-case basis. In general do not eat too full immediately after going to bed, is not conducive to gastrointestinal peristalsis as well as digestion, may produce flatulence, indigestion, insomnia and other symptoms. It is recommended to go to the hospital as soon as possible for any discomfort.
