5姿勢虐爆腰 醫揭隱藏傷害 超多人愛這樣坐沙發

生活中許多看似舒服又放鬆的姿勢,實際上卻會默默傷害健康。對此,台中光田醫院骨科醫師嚴可倫點出5種常見傷腰姿勢,包括半躺半坐、翹二郎腿、盤腿坐、趴臥及三七步,除了容易腰痠背痛外,甚至可能導致四肢麻木、椎間盤突出等問題。其中他提到,半躺半坐是不少人賴在沙發上時,很喜歡的姿勢,但對於頸椎、脊椎來說,都會造成極大壓力,不可不慎。
若總是感覺全身痠痛、手麻腳麻,務必要檢視一下平常姿勢是否需要調整。醫師嚴可倫就在個人粉專發文,介紹以下5種常見的傷腰姿勢,值得民眾特別注意:
1、半躺半坐:不論是坐著或躺在沙發上,把身體半後躺的坐姿是許多人很喜歡的姿勢,看似很放鬆,其實會對腰部產生隱形傷害。當半躺半坐時,會將上半身的力量放在脊椎上,同時頸椎及脊椎也會呈現懸空與彎曲狀態,長時間下來承受較大負擔和壓力,進而產生發炎或受傷的情況,甚至演變成上背痛、坐骨神經痛、椎間盤突出等。
2、翹二郎腿:此動作會使身體長期處於不平衡的狀態,同時增加脊椎壓力,腰部肌肉也會因為代償緊繃而感到痠痛。不僅容易造成腰痠背痛,更可能導致骨盆歪斜、椎間盤突出、筋膜發炎等問題。
3、盤腿坐:是許多人席地而坐時的習慣姿勢。其會呈現上身前傾、骨盆後傾的姿勢,使脊椎過度彎曲,且將壓力集中在腰椎及下背,長期下來就容易出現腰酸背痛、骨盆歪斜、椎間盤突出等不適症狀。
4、趴臥:此姿勢看似有支撐住身體,但其實大多是使用脊椎、背部肌肉出力,而全身壓力也會在腰椎上,長期下來易造成腰痛、脖子僵硬、肩頸緊繃的問題。
5、三七步:搭車通勤或久站腳酸時,常會站三七步放鬆一下,然而,其會使髖部歪斜或一高一低,同時讓腰椎胸椎旋轉,長期下來易造成髖部肌肉無力,連帶導致其它肌肉過度代償而緊繃、腰酸背痛等負面影響。
