If the human body spends half of its time resting, then its mental state will be very good when it is awake. A proper lunch break can promote work efficiency in the afternoon and also benefit physical health. It is best to sleep between 1:00 and 2:00 p.m., but don't sleep too long, otherwise it will be counterproductive. After lunch, taking a short walk and then taking a nap is conducive to healthy sleep. Half an hour to 2 hours, there are some "skills" to taking a nap. Busy work and tight pace often make people unable to cope with it, so naps have become an important guarantee for many people's work day. Experts believe that taking a nap can not only enhance physical strength, eliminate fatigue, and improve work efficiency in the afternoon, but also enhance the body's protective function. However, there are many things to pay attention to when taking a nap, and only a reasonable nap method can achieve the best results. First, don’t rush to take a nap after a meal. Many people are accustomed to sleeping after lunch. At this time, the stomach has just been filled with food, a large amount of blood flows to the stomach, blood pressure drops, and the brain's oxygen and nutrition supply decreases significantly. Falling asleep immediately will cause insufficient blood supply to the brain. Therefore, it is best to exercise for 10 minutes before taking a nap to facilitate food digestion. The second is to pay attention to the time of falling asleep. Most people think that just taking a nap at noon will achieve the desired effect. However, experts have analyzed that the easiest time for people to fall asleep is 8 hours after getting up in the morning or 8 hours before going to bed at night, which is around 1 o'clock in the afternoon. Because people's alertness is naturally declining at this time, taking a nap will help the body get a good rest. Third, pay attention to hygiene during nap. Don't eat too greasy food or eat too full before going to bed, because greasy food will increase blood viscosity and aggravate coronary artery disease, and overeating will increase the burden on stomach digestion. In addition, you can drink a glass of water after waking up to replenish blood volume and dilute blood viscosity, and then you can do some light activities such as walking. Fourth, the nap should not be too long. Experts believe that a healthy nap is most appropriate for 15 to 30 minutes, and should not exceed 1 hour. If the time is too short, you will not be able to get a rest; if it is too long, you will feel a slight headache and general weakness after waking up, and it will not be easy to wake up. Fifth, don’t sleep on your stomach during your nap. It is understood that most people do not pay attention to their nap posture. Some lie on their stomachs, while others simply sleep on the table. In fact, sleeping at a desk will reduce blood supply to the head, causing a series of symptoms of brain ischemia and hypoxia, such as dizziness, blurred vision, and fatigue after waking up. At the same time, using your hands as a pillow will put pressure on the eyeballs, which can easily induce eye diseases over time. Lying on the table will compress the chest, affecting blood circulation and nerve conduction. |
