Most people will have such a feeling that when they have eaten and drank enough, they will feel sleepy. Especially in the afternoon, there are relatively few in the morning, and the feeling at night is not so obvious. So, why do you feel particularly sleepy after eating? You can consider the following possibilities.

　　【Food needs energy to digest】

　　Our spleen and stomach need to mobilize a lot of blood and energy to the stomach for food processing, gastrointestinal motility and so on. Because the body uses a lot of blood and energy in the process of digesting this food, the blood supply to the brain will be insufficient, and the energy will be concentrated in the stomach, so people often feel sleepy after meals. This is one of the reasons.

　　[Related to the secretion of insulin]

　　The food we eat must contain sugar. Rice, vegetables, etc. contain a lot of sugar. At this time, the body's pancreatic islets will begin to secrete insulin to suppress and balance the rise in blood sugar. At the same time, in addition to inhibiting the rise of blood sugar, it also inhibits the decomposition of protein to a certain extent, and people will feel sleepy at this time. On the other hand, insulin also promotes the entry of potassium ions into our cells, and the body will be in a low potassium state, which will also make us feel sleepy.

　　[Related to parasympathetic hyperactivity]

　　An excitable nervous system promotes absorption speed and capacity, resulting in a drop in blood pressure and a slower heart rate, so we can fall asleep more easily.

　　Not everyone can take a rest after a meal, and for those who do not have a long rest period, this sleepiness will have an impact on their work. So, how to alleviate this drowsy phenomenon?

　　【Exercise after meal】

　　Exercising after a meal is not for you to go for a run or exercise, but to go out for a walk after you feel sleepy after a meal. Adjusting your physical condition and sunbathing can make yourself more awake. Regularly doing such walking exercises can gradually improve your biological clock for naps after meals, allow yourself to gradually adapt to changes in your body, and relieve sleepiness after meals.

　　【Improve the spleen and stomach】

　　People with poor spleen and stomach need more energy and blood to digest food, so people are more prone to sleepiness. Therefore, if you have a bad spleen and stomach, you need to regulate your spleen and stomach to improve the health of your spleen and stomach. In this way, the energy and blood required will be reduced, and you will be less prone to drowsiness.

　　【Develop the habit of drinking tea】

　　Drinking tea can help boost our spirits, because tea contains caffeine, an ingredient that can help us get rid of sleepiness. Therefore, you can develop the habit of drinking tea after meals, which not only helps digestion, but also makes you less sleepy. Or, coffee also has caffeine in it, which can play a refreshing role.
