It has been reported that the change in photoperiod induced by the occurrence of daylight saving time has an effect on psychiatric presentation. We therefore investigated the impact of daylight saving time in three conditions: (1) parasuicide presentations; (2) psychiatric outpatient contacts, and inpatient admissions; (3) registered suicides. Results indicate that neither the change in photoperiod nor the effect of a small change in circadian rhythm associated with daylight saving time has an effect on 'cases' in any of the three conditions.
据报道，夏令时出现所引发的光照周期变化会对精神症状产生影响。因此，我们在三种情况下研究了夏令时的影响：（1）准自杀情况；（2）精神科门诊接触、住院收治情况；（3）登记在案的自杀情况。结果表明，无论是光照周期的变化，还是与夏令时相关的昼夜节律微小变化的影响，在这三种情况中的任何一种下，均未对“病例”产生影响。
