“其寝寐床榻,不须高广。比常之制,三分减一,低,则易于升降;狭,则不容漫风。”这段话出自北宋陈直所著的老年养生专著《养老奉亲书》。这里面提出了老年人睡觉的床榻高与宽的细节设置问题。虽然是在遥远的北宋年间提出的,但是无独有偶,2008年的美国《波士顿环球报》也有报道指出,老人在家防摔倒,不仅要考虑灯光、地面,一些家具如床的高度也必须有讲究。如果床太高,老人坐下时不得不身体前倾,没有扶手支撑,容易失去重心。 “This bedtime couch, not high and wide than the usual system, one-third less, lower, then easy to lift; narrow, you can not diffuse. ” This passage from the Northern Song Dynasty Chen straight old age monographs “Parents worship pro-book.” There is a question of setting the details of the bed height and width for the elderly to sleep in. Although it was proposed in the distant Northern Song Dynasty, it was not surprising that the Boston Globe newspaper in 2008 also reported that the elderly should not only fall into the ground at home but also consider lighting and the ground. Some furniture, such as the height of a bed, must also be emphasized. If the bed is too tall, the elderly have to lean forward while sitting down, without armrests, and lose their center of gravity.
