Effects of abstaining temporarily from tobacco smoking were studied in a group of habitual smokers during a 15-day period, during which they smoked normally for the forst 5 days, refrained from smoking the next 5 days, and smoked again during the last 5 days. Results were evaluated against values obtained in a nonabstaining group of smokers. Adrenaline and noradrenaline excretion decreased, skin temperature increased, and hand steadiness was improved when the subjects stopped smoking. Submaximal, physical work tests were performed once each period. No changes occurred in perceived exertion for abstainers during work, in spite of a reduced heart rate. There were only minor differences between abstaining and smoking subjects with regard to performance in the cognitive tests. Irritation, depression, lack of concentration, sleep disturbances, anxiety, tension, and restlessness were frequently reported as abstinence symptoms. The results indicate a decrease in arousal level during abstinence.
在15天的时间里，对一组习惯性吸烟者暂时戒烟的影响进行了研究。在此期间，他们前5天正常吸烟，接下来5天戒烟，最后5天再次吸烟。将结果与一组不戒烟的吸烟者所获得的值进行评估。当受试者停止吸烟时，肾上腺素和去甲肾上腺素排泄减少，皮肤温度升高，手部稳定性得到改善。每个阶段进行一次次最大体力工作测试。尽管心率降低，但戒烟者在工作期间的主观用力感觉没有变化。在认知测试表现方面，戒烟者和吸烟者之间只有微小差异。烦躁、抑郁、注意力不集中、睡眠障碍、焦虑、紧张和坐立不安等常被报告为戒断症状。结果表明，戒烟期间觉醒水平降低。
