Nowadays, many people have the habit of taking a nap in the afternoon. However, in the outpatient department, some patients often fall asleep or catch cold during the nap because they lie prone. So, is it necessary to take a nap? How can I have a high-quality nap? Let's hear what the experts say. What are the benefits of taking a nap? Who needs to take a nap? Wu Hao, member of the general medicine professional committee of the Beijing Institute of Neurology: Taking a nap can make your body healthier, and you can have enough physical strength to exercise in the afternoon. Therefore, a nap is appropriate or necessary for all people. Experts suggest that people engaged in high-intensity physical or mental work, teenagers, children and the elderly, especially need a nap. Wu Hao, member of the general medicine professional committee of the Beijing Institute of Neurology: Because during the nap, children are developing in all aspects, such as brain growth and hormone secretion; The elderly also suggest taking a nap, because the elderly's body is actually deteriorating, so taking a nap in the afternoon will supplement their physical strength. When and how long do you suggest to take a nap? Wu Hao, member of the general medicine professional committee of the Beijing Institute of Neurology: It is generally recommended to sleep after lunch. It is best to take a nap between 12:00 and 13:00. The nap time should not be too long. It is generally recommended to take about 30 minutes. It should be 15 to 30 minutes. Of course, it should not exceed one hour at most. Any more will affect the rest at night. What is the best position for taking a nap? It is suggested that you should pay attention to protecting your cervical vertebra when sleeping on your stomach. If possible, you'd better lie on your back in bed. For office people or school students, if there is no condition for lying down, they can also lie on the chair. If they choose to sleep on their stomach, they should pay attention to protecting their cervical vertebrae. Wu Hao, member of the general medicine professional committee of the Beijing Institute of Neurology: I meet people who sleep on their stomach for a long time in the outpatient clinic and fall asleep, such as neck pain, or neck and shoulder discomfort. Because when sleeping on the stomach, the neck is arched and twisted, so the muscles of the whole neck are not relaxed. If there is really no way to sleep in the office, it is recommended to use a pillow to sleep, and the neck will be raised, not so arched, not so forward bent, and will also make your neck and shoulder muscles soft. Do you need a quilt for a nap? Wu Hao, member of the general medicine professional committee of the Beijing Institute of Neurology: We must pay attention to cold prevention and warmth, because it is a very bad thing to catch a cold while sleeping. It is certainly very good to have a small blanket or a thin quilt. (Outlook New Times)
