Background: In addition to the serotonergic system, the central dopaminergic system has been reported to be correlated with seasonality. The aim of this study was to explore the difference in striatal dopamine D2/D3 receptor availability between healthy volunteers who had a high-sunshine exposure and those who had a low exposure. Methods: Sixty-eight participants were enrolled, and those in the upper and lower quartiles in terms of sunshine exposure were categorized into high- (n=17) and low-sunshine-exposure (n=18) subgroups. Single photon emission computed tomography with [123I] iodo-benzamide was used to measure striatal dopamine D2/D3 receptor availability. Results: Striatal dopamine D2/D3 receptor availability was significantly greater in the subjects with high-sunshine exposure than in those with low-sunshine exposure (F=7.97, p=0.01) after controlling for age, sex, and smoking status. Limitations: Different subjects were examined at different time points in our study. In addition, the sex and tobacco use distributions differed between groups. Conclusion: The central dopaminergic system may play a role in the neurobiological characteristics of sunshine-exposure variation.
