根據一項新研究的結果,磨牙和咬緊牙關——一種被稱為睡眠磨牙症的疾病——是繼夢話和打鼾之後第三常見的睡眠障礙。事實上,研究人員在《胸腔》雜誌的 1 月刊中寫道,超過 8% 的人在睡眠期間至少每週一次咬緊和摩擦牙齒。這些人中有一半報告有牙齒異常磨損或肌肉不適,或者磨牙磨得非常厲害,以至於他們的床伴都能聽到。更重要的是,睡眠磨牙症似乎與其他睡眠和精神障礙有關。

斯坦福大學研究員 Maurice M. Ohayon 及其同事分析了從義大利、德國和英國超過 13,000 名參與者處收集的資料。研究小組發現,與不磨牙的人相比,磨牙的人更容易患上打鼾和睡眠呼吸暫停(一種以呼吸暫時中斷為特徵的疾病),以及焦慮症和幻覺。大約 69% 的睡眠磨牙症患者將他們的病情與壓力、焦慮或煩躁聯絡起來。新資料進一步表明,磨牙症與性別無關,並且隨著年齡的增長而顯著減少。

Ohayan 建議,如果全科醫生和牙醫在患者身上觀察到牙齒異常磨損,應詢問磨牙症和睡眠呼吸暫停,並指出“有必要對這種在很大程度上未知的睡眠障礙的病理生理機制進行進一步研究。”

She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
