1 腰酸背痛为何找上门？ 春节假期宅家休闲，免不了久坐久躺，长期保持此类姿势易引发腰酸背痛。让我们一起动起来，用几组 居家动作搭配日常习惯调整，改善久坐久躺带来的僵硬不适，保持健康舒适的状态，开开心心过大年！ 春节假期里，很多人认为"瘫在沙发上""躺着刷手机"是放松，但这种静态、不良姿势反而会让腰背部、 颈椎的肌肉和韧带持续处于紧张状态，破坏脊柱的生物力学平衡，引发疼痛。 一方面，长时间躺卧时，为了维持身体姿势（如半躺时腰部悬空、侧躺时脊柱扭曲），腰背部、颈椎的 肌肉需要持续收缩以保持稳定。这种长时间的静态收缩会导致肌肉内血液循环受阻，乳酸、炎症介质等 代谢废物在局部堆积，进而刺激神经末梢，引发酸痛感； 另一方面，人正常脊柱有四个生理曲度（颈曲、胸曲、腰曲、骶曲），这些生理曲度能缓冲震荡、维持 平衡，但不良躺卧姿势会破坏这些曲度。此外，一些看似静止的姿势，实则肌肉仍在"隐性工作"。例 如，躺着刷手机时，手臂需举着手机（或支撑在身体两侧），肩部肌肉持续紧张。这种"静态疲劳"会逐 渐累积，最终导致疼痛。 2 4组在家就能做的简单动作 帮助放松肌肉、缓解酸痛 1.懒猫弓背：跪姿，双手双膝撑地，手腕对齐肩膀，膝盖对齐 ...

Core Viewpoint - The article emphasizes the importance of maintaining bone health, particularly in individuals aged 30-35 and older, to prevent conditions like osteoporosis and associated fracture risks. It highlights the prevalence of low bone mass in the population and suggests a three-step strategy for bone health management. Group 1: Prevalence and Risks - The peak bone mass is reached in youth, and after age 30-35, there is a gradual decline leading to low bone mass, which can progress to osteoporosis if not addressed [1] - In China, the prevalence of low bone mass is 40.9% among individuals aged 40 and above, and 47.5% among those aged 60 and above [1] Group 2: Step 1 - Scientific Assessment - Individuals should calculate their BMI using the formula: weight (kg) ÷ height (m)², aiming for a healthy range of 18.5-23.9 for adults aged 18-64 [2] - Weight changes should be monitored, especially in older adults, with specific BMI targets set for different age groups [2] - Regular bone density tests are recommended for those over 40 or with risk factors, using various screening methods to identify low bone mass early [2] Group 3: Step 2 - Nutritional Reinforcement - Adequate calcium intake is crucial, with recommendations of 300-500 ml of dairy products daily, along with increased consumption of soy products and dark green vegetables [3] - Vitamin D supplementation is advised through outdoor activities and diet, including fatty fish and egg yolks [4] - Sufficient intake of high-quality protein from fish, poultry, eggs, lean meats, and legumes is essential for bone health [5] Group 4: Step 3 - Effective Exercise - Regular physical activity is vital, with a recommendation of at least 150 minutes of moderate-intensity exercise weekly, adjusted for older adults [6] - Aerobic exercises such as running, walking, swimming, dancing, and cycling are effective for stimulating bone growth [7] - Strength training exercises, including resistance training with bands or weights, are recommended to enhance muscle strength and protect bones [7]
