Just after lunch, my stomach was full of food and my digestive function was in motion. For example, taking a nap at this time will affect the digestion of the gastrointestinal tract, which is not conducive to the absorption of food, and it will cause stomach problems for a long time; At the same time, it also affects the quality of siesta. It is advisable to fall asleep half an hour after supper.

2. Pay attention to the sleeping posture

It is generally believed that the correct posture to sleep is lying on the right side, because it can reduce the burden on the heart, increase the blood flow in the liver and facilitate the digestion and metabolism of food.

But in fact, because the nap time is short, you don't have to force yourself to lie to the left, to the right or to lie flat, as long as you can fall asleep quickly. Relax the belt, facilitate gastrointestinal peristalsis and help digestion. If you are taking a nap at your desk, it is best to put something soft and high under your armpit, which can reduce the squeeze and make it easier to fall asleep.

3. Pay attention to hygiene before taking a nap

Don't eat too greasy things before going to bed, and don't eat too full, because greasy will increase blood viscosity and aggravate coronary artery disease, and satiety will increase the digestive burden of the stomach. In addition, after waking up, you can drink a glass of water to replenish blood volume and dilute blood viscosity, and then you can do some light activities such as walking.

In the morning, people's energy is always vigorous, because after a night's rest, the internal functions of the body have been rested, and the fatigue of the previous day has disappeared.

At this time, the physiological function not only needs to compensate the consumed calories, but also needs to properly eliminate fatigue and restore energy so as to work and study better in the afternoon.
