中新网8月7日电 近年来，随着人们生活节奏的加快和工作方式的改变，久坐和久躺成为了许多人的常态。然而，专家指出，这两种姿势对身体都有潜在的负面影响。
根据腰椎的结构，平躺确实对腰椎压力最小，但在床上看手机或阅读时，长时间保持一个姿势，会对腰部造成额外压力。此外，久躺不动会导致热量消耗降低，增加肥胖的风险。
相比之下，久坐尤其是长时间看手机或电脑屏幕，会给腰部带来更大的压力。长时间保持同一姿势，不仅会影响腰椎健康，还可能导致肌肉紧张和血液循环不畅。
专家建议，无论久坐还是久躺，都应该定期起身活动，进行适量的体育锻炼，以保持身体的灵活性和健康。同时，保持正确的坐姿和躺姿，避免长时间低头看手机，可以减少对颈椎和腰椎的压力。
总之，无论是久坐还是久躺，都不利于身体健康。保持适量的活动和正确的姿势，才是维护腰椎健康的最佳方式。

Title: “Long Spells of Lying Down Might Hurt Your Back? Experts Explain the Health Risks of Prolonged Sitting and Lying”
Keywords: Long Spells of Lying Down, Health, Lumbar Spine

BEIJING, Aug. 7 (Xinhua) — In recent years, as people’s lifestyle accelerates and work patterns change, prolonged sitting and lying down have become the norm for many. However, experts point out that both postures have potential negative effects on the body.
According to the structure of the lumbar spine, lying flat indeed puts the least pressure on the lumbar spine. However, when reading or using a smartphone on the bed, maintaining the same posture for a long time can exert additional stress on the waist. Moreover, prolonged lying without moving can reduce calorie consumption and increase the risk of obesity.
In comparison, prolonged sitting, especially when looking at a smartphone or computer screen for long periods, can exert greater pressure on the waist. Maintaining the same posture for a long time not only affects the health of the lumbar spine but can also lead to muscle tension and poor blood circulation.
Experts recommend that regardless of whether one is sitting or lying down for a long time, one should regularly get up and move, engaging in appropriate physical exercise to maintain body flexibility and health. Additionally, maintaining correct posture while sitting and lying down, and avoiding prolonged head-down use of smartphones, can reduce pressure on the cervical and lumbar spines.
In summary, neither prolonged sitting nor lying down is beneficial for one’s health. Maintaining appropriate movement and correct posture is the best way to maintain the health of the lumbar spine.
