一般地说,人们每天约有三分之一的时间是在枕头上度过的。一个人睡眠的好坏,枕头可谓至关重要的一种寝具。俗话说:“高枕无忧”,意即枕头垫得高高的,能无忧无虑地睡大觉。其实,影响一个人的睡眠,往往与枕具的质地密切相关。据有关专家研究,人入睡以后,头部的温度一般在34—34.5℃,比体温要低几度,如果头部的温度过高,就不容易入睡。现在家庭中日常使用的以荞麦、木棉或塑料泡沫为枕蕊的枕头,由于所填的物料不透气、不容易散发头部所产生的热量,因此,入夏后人们喜欢在上面系一块枕席,其作用是使体热经传导散发到枕上,这样头部就会感到凉爽,容易使人入睡。古人对上述现象不一定能上升到科学的角度予以阐述,但我国古代的一些枕具大都以清火、安神为目的。文献 In general, people spend about a third of their time on the pillow. A person’s sleep is good or bad, the pillow can be described as a vital bedding. As the saying goes: “sit back and relax”, which means that the pillow was so tall, you can sleep well-consciously. In fact, the impact of a person’s sleep, often with the texture of the pillow is closely related. According to experts, people fall asleep after the head temperature is generally 34-34.5 ℃, lower than the temperature a few degrees, if the head of the temperature is too high, it is not easy to fall asleep. Nowadays, the pillows that use buckwheat, kapok or plastic foam as their pillow in their homes are not easy to distribute the heat generated by the head because of the airtightness of the filled materials. Therefore, after summer, people like to wear a pillow seat on the pillow, Its role is to heat the body heat transmitted to the pillow, so the head will feel cool, easy to make people fall asleep. The ancients did not necessarily explain the above phenomenon to a scientific point of view, but in ancient China some pillows mostly aimed at clearing fire and soothe the nerves. literature
