新的研究表明,蒸发损害血液流动和氧气水平,挑战其更安全的替代形象。 New study shows vaping harms blood flow and oxygen levels, challenging its safer alternative image.

一项新的研究表明,即使没有尼古丁,抽吸也立即对血管和身体氧气水平产生消极影响。 A new study reveals that vaping, even without nicotine, has immediate negative effects on blood vessels and oxygen levels in the body. 研究人员发现，电子烟会减少股动脉中的血流量并降低静脉氧饱和度，这表明肺部的摄氧量减少。 Researchers found that vaping decreases blood flow in the femoral artery and reduces venous oxygen saturation, suggesting less oxygen uptake by the lungs. 这份在北美放射学会上介绍的研究挑战了一种观点,即e-cigarettes是传统香烟的更安全替代品。 This research, presented at the Radiological Society of North America, challenges the view that e-cigarettes are a safer alternative to traditional cigarettes. 该研究涉及 31 名年龄在 21 至 49 岁之间的健康参与者，并强调了电子烟的潜在长期健康风险。 The study involved 31 healthy participants aged 21 to 49 and highlights the potential long-term health risks of vaping.
