Nostalgia is shown to relieve an individual's perception of pain evoked by cold water, pressure, and thermal stimuli. However, there is no direct evidence to show the analgesic effects of different nostalgia-inducing methods on various stimulus intensities. We conducted two studies to examine the analgesic effect, at different pain intensities, after inducing nostalgia either idiographically or nomothetically. Study 1 (N = 118) induced nostalgia through an idiographic approach (i.e., event reflection task) and found that nostalgia relieved both high and low thermal pain. Study 2 (N = 66) induced nostalgia through a nomothetic approach (i.e., viewing nostalgic pictures) and found that nostalgia relieved low but not high thermal pain. The findings verify the analgesic effect of nostalgia on thermal pain and suggest the potential moderating role of the nostalgia induction approach and pain intensity. Practically, these findings have implications for using nostalgia as a nonpharmacological treatment for pain.

具体和常态方法对热刺激引起的怀旧镇痛作用

怀旧被证明可以减轻个人对冷水、压力和热刺激引起的疼痛的感知。然而，没有直接的证据表明不同的怀旧诱导方法对各种刺激强度的镇痛作用。我们进行了两项研究，以检查在不同的疼痛强度下，在具体地或无意识地诱导怀旧之后的镇痛效果。研究 1 ( N = 118) 通过具体的方法（即事件反射任务）诱发怀旧，发现怀旧可以缓解高热痛和低热痛。研究 2 ( N= 66) 通过常态方法（即观看怀旧图片）诱发怀旧，发现怀旧减轻了低热痛，但不能缓解高热痛。研究结果证实了怀旧对热痛的镇痛作用，并表明怀旧诱导方法和疼痛强度的潜在调节作用。实际上，这些发现对使用怀旧作为疼痛的非药物治疗具有重要意义。
