How long after lunch is a good time to take a nap.

Suitable for a nap after 20 minutes after eating.

After a meal, a large amount of blood flows to the stomach, blood pressure drops, and the oxygen supply and nutrition to the brain drop significantly, which will cause insufficient blood supply to the brain, and in severe cases, reflux esophagitis may occur. Don't eat too much or greasy lunch, and move for 10 minutes before napping to allow food to digest; It is best to rest for about 20 minutes before taking a nap.

In addition, when the human body is asleep, the muscles relax, the heart rate slows down, the blood vessels dilate, the blood pressure decreases, and the blood flow to the brain is relatively reduced. Especially after lunch, more blood enters the stomach and intestines, and if you sit and sleep again, the brain will be deprived of oxygen after a long time, causing people to feel uncomfortable such as heavy head, fatigue, and weak legs. Sleeping on the table will compress the chest, hinder breathing, and increase the burden on the heart and lungs.

It is better to take a nap in the right position, because this can reduce the burden on the heart, increase the blood flow to the liver, and facilitate the digestion and metabolism of food. However, due to the short nap time, you don't have to force the left, right, and flat positions to sleep, as long as you can lie down and fall asleep quickly.

Take a nap at least half an hour after eating. It is not advisable to fall asleep immediately after eating, because the digestive system is in a working state after eating, at this time, napping will reduce digestive function, and will also make blood flow to the stomach, blood pressure will drop, and the brain will supply nutrients to the obvious insufficiency, which is easy to cause insufficient blood supply to the brain, and will cause stomach problems in the long term. In addition, it is recommended not to eat too full, too greasy or spicy before bedtime.

After eating, you can take a walk and do some soothing exercises, which can not only strengthen the body, but also allow food to be well digested and promote the absorption of nutrients. There are many dangers of going to bed immediately after eating, so it is recommended to go to bed more than 20 minutes after lunch. 1.

The harm of sleeping immediately after eating: when the stomach is in a full state after eating, if you lie down to sleep immediately, it may cause gastric acid to flow into the esophagus, and gastric acid is acidic, which will not only break the alkaline environment of the ring esophagus, but also corrode the esophagus, resulting in the emergence of esophageal diseases; Sleeping immediately after eating enough can also lead to gaining weight. 2.

Precautions after eating: Do not brush your teeth immediately after eating, because after chewing food, the oral environment is in an acidic environment, which will cause the calcium ions on the surface of the teeth to detach from the surface of the teeth in an acidic environment, if you brush your teeth immediately at this time, the calcium ions have no way to return to the surface of the teeth, thus causing damage to the teeth, so it is recommended to rinse your mouth after eating, if you brush your teeth should be more than 30 minutes after eating; Taking a walk immediately after a meal will cause the blood that would otherwise flow into the stomach to the extremities, which will lead to insufficient blood supply to the stomach, resulting in insufficient gastric motility and indigestion.
