Here's an explanation for sleep inertia: just like a moving vehicle suddenly braked, inertia causes you to lean forward in the car. As the name implies, sleep inertia is that you are suddenly awakened when you are sleeping soundly, and your consciousness has awakened, but your body is still in a state of dullness and weakness. In severe cases, you will be dizzy and have behavioral disorders.
The school of psychology of Flinders University in South Adelaide, Australia, made a detailed study on the nap behavior. Studies have shown that all the naps (but only 5 minutes to 2 hours were tested in the study) have been proved to be beneficial to improve cognitive function. However, due to the existence of sleep inertia, these "benefits" will have obvious differences in different lengths for a period of time after a nap. A long nap will reduce your cognitive function for a short time when you wake up, and then rise.
The European Institute of Applied Physiology and Occupational Physiology conducted a small test. They randomly selected 30 healthy subjects who slept normally at home the night before and divided them into three groups. After lunch, they randomly arranged three different naps (0 minutes, 15 minutes and 45 minutes) and recorded the data. In this study, scientists found that taking a nap 15-45 minutes after lunch can effectively improve the follow-up alertness, reduce subjective drowsiness and improve the completion of work tasks without affecting the quality of sleep that night.
It is generally believed that a period of sleep after study, even if it is just a nap, can promote the consolidation of memory, and sleep helps to stabilize the information obtained before going to bed. Here, let's first distinguish the difference between procedural memory and declarative memory-if you learn how to cook a delicious dish in Zhihu, then remember the cooking steps and seasonings needed for this dish, which is declarative memory; After trying it once, you not only remember the recipe, but also learn how to grasp the heat and spoon, and finally you can adjust the details according to your taste. This is procedural memory.
There is a lot of evidence to support the view that sleep helps to consolidate newly formed memories. Many behavioral studies show that studying before going to bed, rather than during the same waking hours, is beneficial to measure the performance of various tasks of different types of memory, such as implicit, procedural or explicit, declarative memory. The activity process corresponding to different neurochemical states during sleep helps to strengthen new memory traces, making them stable and free from interference.
For declarative memory dependent on hippocampus, non-rapid eye movement sleep (n REM, 1-4 stage), especially slow wave sleep (SWS, 3-4 stage combination) is considered to be helpful to transfer the memory burden from short-term dependence on hippocampus to long-term storage in neocortex, a process called system integration. Moreover, because increasing the delay between study and sleep will significantly improve the performance from study to memory test, scientists suggest waking up for a period of time, further processing neutral memory, strengthening memory traces, and making it more prominent (that is, making a small review summary after studying in the morning). When memory is strengthened, sleep can play a role in promoting memory retention.
The answer is naturallyno. If you don't have the habit of taking a regular nap, that is, the number of naps is less than three times a week, then the act of rashly increasing the nap may lead to a decline in the quality of sleep at night, and it will take two weeks or even longer to get used to it. Secondly, patients with the following diseases should reduce the number of naps or shorten the nap time. In fact, taking a nap at noon can bring some benefits to the body, but even if you don't take a nap, it won't do any harm to the body, and a short nap can also bring the effect of restoring spirit and improving memory.
As the saying goes, "Yang is tired and you lie down, while Yin is tired and you lie down". Chinese medicine believes that noon and noon are the time when yin and yang alternate, and also the time point when human meridians and qi "merge yin" and "merge yang". Rest at this time is helpful for nourishing yin and strengthening yang, and it is the time period with the best sleep quality and twice the result with half the effort. However, the incorrect nap can not only achieve the effect of repair and health preservation, but even cause damage to the body.
"If the inflammatory atmosphere sweats, it will be annoying to sleep in the afternoon; A moment in wonderland, sleeping in the north window is refreshing. " A good nap can not only bring abundant vitality to work and study in the afternoon, but also effectively regulate the biological clock of human health, but be careful not to oversleep! Be sure to take a nap. The end of senior three is a sprint of physical strength. In the late third year of senior high school, people who are never sleepy in our class will feel tired, so we must have a good rest and exercise. ""Don't just sit in the classroom and brush the questions after class. Maybe you can do it now, but in the later stage, you may be practicing brushing questions in every class with high intensity. If you don't rest in class, your brain won't turn around. "
In a word, about taking a nap, you must take a nap, find a time that suits you, don't sleep too long, just sleep in the afternoon and be energetic. Finally, I really don't have to worry too much that my rest time will affect the progress of senior three. What you really get is high class efficiency. You don't need to worry about yourself because of the involution of your classmates around you, just keep your own rhythm and high efficiency.
