引言：众所周知，有些人用酒精来自我抑制他们的焦虑。虽然有很多证据表明，酒精消费可以产生负面影响，但关于酒精和焦虑之间的关系仍然存在不确定性。一个未被探索的可能性是，对一些人来说，酒精损害了内感受灵敏度（准确感知一个人生理状态的能力），从而减少了状态焦虑。与此一致，高度准确的心跳感知是特质焦虑和焦虑症升高的风险因素。然而，直接影响酒精对cardioceptive的准确性还没有我们的知识以前examined.Methods：61社会饮酒者来到实验室的4-6组间隔一周的两天。每个参与者被随机分配在一个测试日接受BAC为0.05%的酒精饮料，另一个测试日接受安慰剂饮料，顺序平衡。在这两个测试日，参与者在三个场合进行Schandry心跳感知任务：在基线，酒精吸收期后，和生理唤醒后通过exercise.Results提高：仅对男性来说，酒精显着损害心脏感受准确性相对于安慰剂在低和高水平的唤醒，具有中等至大的影响大小。结论：虽然是初步的，但这一发现与酒精消费和焦虑有关的假设是一致的，至少对男性来说是这样。未来的研究应该直接检查是否，在焦虑症患者中，心脏敏感性介导饮酒和状态焦虑之间的关系。
Introduction: It is well established that some individuals self-medicate their anxiety with alcohol. Though much evidence exists that alcohol consumption can be negatively reinforcing, there remains uncertainty regarding what mediates the relationship between alcohol and anxiety. An unexplored possibility is that, for some, alcohol impairs interoceptive sensitivity (the ability to accurately perceive one's physiological state), thereby decreasing state anxiety. Consistent with this, highly accurate heartbeat perception is a risk factor both for elevated trait anxiety and anxiety disorders. However, the direct impact of alcohol on cardioceptive accuracy has not to our knowledge been previously examined.Methods: Sixty-one social drinkers came to the lab in groups of 4-6 on two days spaced a week apart. Each participant was randomly assigned to receive alcoholic drinks targeting a BAC of 0.05% on one testing day and placebo drinks on the other, with the order counter-balanced. On both testing days, participants engaged in a Schandry heartbeat perception task on three occasions: at baseline, after an alcohol absorption period, and after physiological arousal was raised via exercise.Results: For men only, alcohol significantly impaired cardioceptive accuracy relative to a placebo at both low and high levels of arousal, with medium to large effect sizes.Conclusions: Though preliminary, this finding is consistent with the proposed hypothesis linking alcohol consumption and anxiety, at least for men. Future studies should directly examine whether, among individuals with anxiety disorders, cardioceptive sensitivity mediates the relationship between alcohol consumption and state anxiety.
