社交技术在世界各地的年轻人中被广泛使用，有人认为，打断对这项技术的访问会引发焦虑。然而，社会技术限制对年轻人焦虑和自主活动的影响尚未得到正式研究。因此，我们假设社会技术的限制会增加状态焦虑，并改变神经心血管对动脉血压的调节。21名大学生(年龄18-23岁)在连续两周内接受了社会技术使用正常或受限的检查(随机交叉设计)。分别在静息状态和几种典型的自主神经应激状态下测量平均动脉压(MAP)、心率和肌交感神经活动(MSNA)，包括等长握力、运动后肌肉缺血、冷加压试验和精神应激。三分分析显示，社会技术的限制与状态焦虑的增加(12±2 Au；范围5至21；n=7)、减少(−6±2 Au；范围−2至−11；n=6)或无变化(0±0 Au；范围−1至3；n=8)相关。社会技术限制不会改变安静时的MAP(74±1对73±1 mm Hg)、心率(62±2对61±2次/分)或MSNA(9±1对9±1次/分)，也不会改变神经或心血管对急性应激源的反应。总而言之，社会技术限制似乎对焦虑有个体间的影响，但对自主活动没有影响。目前尚不清楚反复发作或社会技术的长期限制如何影响长期的心理和心血管健康。
Social technology is extensively used by young adults throughout the world, and it has been suggested that interrupting access to this technology induces anxiety. However, the influence of social technology restriction on anxiety and autonomic activity in young adults has not been formally examined. Therefore, we hypothesized that restriction of social technology would increase state-anxiety and alter neural cardiovascular regulation of arterial blood pressure. Twenty-one college students (age 18–23 yr) were examined during two consecutive weeks in which social technology use was normal or restricted (randomized crossover design). Mean arterial pressure (MAP), heart rate, and muscle sympathetic nerve activity (MSNA) were measured at rest and during several classic autonomic stressors, including isometric handgrip, postexercise muscle ischemia, cold pressor test, and mental stress. Tertile analysis revealed that restriction of social technology was associated with increases (12 ± 2 au; range 5 to 21;n= 7), decreases (−6 ± 2 au; range −2 to −11;n= 6), or no change (0 ± 0 au; range −1 to 3;n= 8) in state-anxiety. Social technology restriction did not alter MAP (74 ± 1 vs. 73 ± 1 mmHg), heart rate (62 ± 2 vs. 61 ± 2 beats/min), or MSNA (9 ± 1 vs. 9 ± 1 bursts/min) at rest, and it did not alter neural or cardiovascular responses to acute stressors. In conclusion, social technology restriction appears to have an interindividual influence on anxiety, but not autonomic activity. It remains unclear how repeated bouts, or chronic restriction of social technology, influence long-term psychological and cardiovascular health.
