这个有点“不雅”的坐姿,其实对人体有很多好处!
网上有种说法称:虽然有点“不雅观”,但叉开腿坐能更好地保持脊柱中立,有助于腿部血液循环等,是个不错的坐姿,尤其对于女性而言有不少好处。

叉开腿坐有啥好处?
先要明确的是,正确坐姿的关键只在一点:脊柱要和地面垂直,跟双腿是否张开关系不大。
Experts say healthy sitting depends primarily on keeping the spine upright and aligned, rather than whether the legs are closed or apart.
这种坐姿主要有这些好处:
▌保护脊柱
有研究显示,并腿坐时,即使坐得端正,也会给脊柱增加40%负担。时间长了,下背部和骨盆区域肌肉容易紧张,出现疼痛和僵硬感。长此以往,还会增加脊柱侧弯风险。
腿叉开时,可让下肢呈现稳定三角形结构,分担上半身压力,让脊柱处于稳定“中立位”,更容易保持一条自然曲线,腰椎、胸椎的旋转扭曲角度也比跷腿或盘腿时要小。减少腰疼和不良体态带来的不适,尤其是怀孕的女性,更适合叉腿坐。
Research suggests that sitting with knees together can increase spinal pressure by up to 40 percent, while placing the feet shoulder-width apart creates a more stable base, helping maintain the spine's natural curve and reduce strain.
▌叉腿坐,对女性骨盆更友好
基于女性身体的构造,坐姿不当时,脊椎扭曲,很容易带着骨盆一起倾斜,影响健康。
而叉开腿端坐,则能够让脊柱和骨盆呈现出稳定的三角结构,相较其他坐姿,骨盆更不易倾斜,自然更有助于保护盆腔内的子宫、卵巢等器官。
而且叉开腿坐,还有助私处通风,保持外阴干燥,减少细菌、霉菌的滋生,降低患阴道炎的概率。
The posture may be particularly beneficial for women, as it helps stabilize the pelvis, protect reproductive organs and improve airflow, potentially lowering the risk of infections.
▌拉伸内收肌群,缓解久坐带来的不适
长时间久坐或运动后,大腿内侧内收肌群可能变得紧张,进而导致腰部、髋部、膝关节等一系列不适。双脚打开、与肩同宽叉腿坐时,左右屁股受力最均匀,可以温和地拉伸这些过度紧张的肌肉。

▌保持放松情绪
坐姿也会影响人的心情?你没看错!在众多有关抑郁、情绪的研究中,都有提到过“扩张姿势”对人体的影响。
简而言之,张开双臂、打开双腿、打开胸背,这种让身体“扩张”的姿势,能有效让人产生积极向上的情绪。
Studies further indicate that "expansive postures", such as opening the limbs and chest, may promote more positive emotions.
具体怎么坐?
虽然好处不少,但叉开腿坐时往往也会伴随着驼背、骨盆后倾等情况,长期如此不利于脊柱健康,可能会加重腰背酸痛、肩颈痛等情况。
具体该怎么叉腿坐,也是有讲究的,要注意“3个90度和1个支撑”:
大腿与腰保持90度;
膝盖与大腿保持90度;
小腿与地面保持90度;
脊柱支撑:使用腰靠垫填补腰椎与椅背的空隙,保持脊柱自然曲度。
However, improper posture can negate these benefits. Slouching or leaning back may still lead to back and neck pain. Experts recommend maintaining three 90-degree angles — at the hips, knees and ankles — and supporting the lower back with a cushion to preserve the spine's natural curve.
在上述基础上,双脚叉开与肩膀同宽,就达到了我们标准的“直立坐”,有助保持下肢平衡,呵护关节健康。
此外,无论男性还是女性,在公共场合需要叉腿坐时,都要注意幅度,保护个人隐私,同时兼顾健康与社交边界感。
这些姿势虽然舒服
但别再这么坐了
① 跷二郎腿→骨盆倾斜、脊柱侧弯、伤膝盖
② 腰部悬空瘫坐→ 腰椎压力爆表,小心腰间盘突出
③ 身体前倾坐→ 腰背肌像拉紧的弦,久了酸疼痉挛
④ 瘫坐半躺→ 脊柱失衡,颈椎腰椎一起受伤
⑤ 过分挺胸→ 反而破坏胸椎自然曲度
Other harmful habits include crossing the legs, slumping without support, leaning forward for extended periods or reclining excessively, all of which can place uneven stress on the spine and joints.
最后,无论坐姿是否正确,久坐都是无益的,建议大家每坐1个小时要站立活动5-10分钟。
Regardless of posture, prolonged sitting is discouraged. People are advised to stand up and move for five to ten minutes every hour.
