《黄帝内经·灵枢·九宫八风》
从北方来的风，名叫大刚风，它伤害到人体，内可侵入于肾，外在于骨骼和肩背的肌腱部；因为北风阴寒至盛，遏伤肾阳，所以其气主寒性病证。
风从北方来，名曰大刚风，其伤人也，内舍于肾，外在于骨与肩背之膂筋，其气主为寒也。
The wind from the north, called da gang feng, harms the human body, and can penetrate the kidneys internally, affecting the muscles, bones, and shoulder blades externally. Because the north wind is extremely cold, it damages the yang energy of the kidneys, and therefore its effects are mostly related to cold diseases.
