背中から腰が痛い　更年期障害

肩こりは、肩甲骨から首の間の筋肉が緊張して、血行が悪くなり、乳酸などの疲労物質が筋肉の中に溜まることで生じます。人間の体は首だけで頭部を支える構造になっているため、その重みで首と肩には負担がかかります。腰痛も、腰の骨に負担がかかり、血行が妨げられ乳酸が溜まって生じます。
また、姿勢が良くないせいで骨格がゆがんで神経を圧迫することで、痛みが出る場合があります。
さらに、女性は男性に比べて、肩の周りの筋肉や腰の周りの骨を支える筋肉が弱いために、症状が出やすいのです。特に更年期以降では加齢による筋骨格系の老化と様々なストレスなどの社会的背景から肩こりが増加すると考えられています。肩こりは、血液循環が悪くなったり、首から肩にかけての筋肉が緊張し続けると発生するので、予防には筋肉の緊張をほぐす運動をこまめに行い、血行を促すことが有効です。

Shoulder stiffness occurs when the muscles between the shoulder blades and the neck become tense, resulting in poor blood circulation and the build-up of fatigue substances such as lactic acid in the muscles. The human body is designed to support the head with the neck alone, so the weight of the head puts strain on the neck and shoulders. Back pain is also caused by strain on the bones in the lower back, which impedes blood circulation and leads to a build-up of lactic acid.
Pain can also be caused by distortion of the skeleton due to poor posture, which puts pressure on nerves.
Furthermore, women are more prone to symptoms than men because the muscles around the shoulders and the bones around the hips are weaker than in men. Especially after menopause, stiff shoulders are thought to increase due to ageing of the musculoskeletal system and social backgrounds such as various stresses. Stiff shoulders occur when blood circulation is poor and muscles from the neck to the shoulders remain tense, so frequent exercise to relieve muscle tension and stimulate blood circulation is effective for prevention.
