In daily life, we often hear the saying: "If you lie down after eating, you are easy to get sick and gain weight." However, in recent years, some doctors have put forward a different view, believing that lying down and resting properly after meals not only does not gain weight, but may also bring certain health benefits. Is this view scientific? What is the medical basis behind it? This article will reveal the truth of this phenomenon from a scientific point of view.
1. The collision between traditional concepts and modern research
Conventional wisdom holds that lying down immediately after a meal will cause food to remain in the stomach, affecting digestion and inducing various diseases. In addition, lying down also reduces the body's metabolic rate, making it easier for calories to be converted into fat, which can lead to obesity. However, modern medical research has found that this notion is not entirely true.
First of all, regarding the retention of food in the stomach, studies have shown that lying down does not significantly affect the rate at which the stomach emptilates. Gastric emptying is mainly regulated by nerves and hormones and has little to do with body position. Therefore, lying down after a meal does not cause food to remain in the stomach for a long time.
Secondly, regarding the question of metabolic rate, although it is true that lying down will reduce the amount of activity in the body, it does not mean that the metabolic rate will drop significantly. Metabolic rate is affected by a variety of factors, such as age, gender, weight, etc., and body position has a relatively small effect on it. Therefore, lying down after a meal does not lead to a significant decrease in metabolic rate, nor does it make it easier for calories to be converted into fat.
2. The health benefits of lying down after meals
Since lying down after a meal doesn't lead to food retention and a decrease in metabolic rate, is it possible to have some health benefits? The answer is yes.
First of all, lying down after a meal helps to reduce the burden on the stomach. When standing or sitting, the stomach needs to be subjected to pressure from gravity, which increases the burden on the stomach and affects digestion. When lying down, the stomach is in a relatively horizontal position, and the effect of gravity on the stomach is reduced, which reduces the burden on the stomach and is conducive to digestion.
Secondly, lying down after a meal can help improve blood circulation. When standing or sitting, blood flows more easily to the lower limbs due to gravity, resulting in a relative shortage of blood in the upper body, especially in the brain. When lying down, the blood is more evenly distributed, which is conducive to improving blood circulation in the upper body and providing sufficient blood and oxygen to the brain and other vital organs.
Finally, lying down after a meal can also help relieve fatigue. After a meal is a period when the body's energy consumption is large, lying down and resting at this time can help the body recover energy and relieve fatigue. This is especially important for people who have been engaged in physical or mental work for a long time.
3. How to lie down and rest after eating scientifically
While there are certain health benefits to lying down after eating, it doesn't mean that you can rest on your own right. Here are some tips to help you lie down and rest after a meal scientifically:
1. Control the lying time: The lying time after meals should not be too long, and it is generally recommended not to exceed 30 minutes. Lying down for too long may cause the body to relax too much, which in turn affects digestion and blood circulation.
2. Choose the right position: When lying down, it is recommended to choose the right side or supine position. These two positions help to reduce the burden on the stomach and improve blood circulation. Avoid prone or left-sided decubitus positions, which can put pressure on the stomach and heart, affecting digestion and circulation.
3. Pay attention to keeping warm: When lying down to rest, pay attention to keeping warm and avoid getting cold. Exposure to the cold may lead to gastrointestinal disorders and affect digestion.
4. Avoid falling asleep immediately: Lying down and resting after a meal is not the same as sleeping. It is advisable to get up and move properly after lying down to rest, and then do other activities or fall asleep. This will prevent the body from being too relaxed and affecting the quality of sleep at night.
Fourth, summary and outlook
From the above analysis, we can see that lying down properly after meals does not lead to food retention and a decrease in metabolic rate, but may bring some health benefits. Of course, this doesn't mean that we can completely upend traditional eating habits and lifestyles. In daily life, we still need to maintain a reasonable diet, moderate exercise and good work and rest habits.
In the future, with the continuous deepening of medical research and the continuous change of people's lifestyles, our understanding of lying down after meals will also be constantly updated and improved. It is believed that in the near future, we will understand this phenomenon more scientifically and apply it to our daily life to bring more benefits to our health.
