一项新研究发现,日光减少与美国自杀率较高相关联。 Less sunlight correlates with higher U.S. suicide rates, a new study finds.

UConn经济学家田中信介的一项新研究发现,阳光照射的减少与美国自杀率的提高密切相关,太阳辐射的单一标准降幅与自杀增加6.76%挂钩,与失业等主要风险因素相比。 A new study by UConn economist Shinsuke Tanaka finds that reduced sunlight exposure is strongly linked to higher suicide rates in the U.S., with a one-standard-deviation drop in solar radiation tied to a 6.76% increase in suicides—comparable to major risk factors like unemployment. 利用以卫星为基础的25年太阳能数据,研究显示,日光较低,特别是由于多云或雨季,与抑郁症上升和与自杀有关的在线搜索相关联。 Using 25 years of satellite-based solar energy data, the research shows that lower sunlight, especially due to cloudy or rainy weather, correlates with rising depression and suicide-related online searches. 研究结果挑战了过去对季节性自杀模式的假设,凸显了阳光在心理健康方面的保护作用,引起了对太阳地球工程的担忧,并强调需要对光照射问题给予更多的公共卫生关注。 The findings challenge past assumptions about seasonal suicide patterns and highlight sunlight’s protective role in mental health, raising concerns about solar geoengineering and underscoring the need for greater public health attention to light exposure.
