极端高温影响大脑功能

极端高温日益常见,而它对大脑和认知功能的影响很多人可能未必了解。极端高温会影响大脑的所有认知功能,包括反应能力、记忆力等。高温下,大脑运转的速度要慢得多。2018 年在美国纽约公立学校开展的一项研究显示,在气温高于 32℃ 的天气下参加考试,与在 22℃ 的天气下参加考试相比,成绩会降低 14%,通过考试的概率也会降低近 11%。另一项在美国进行的研究称,学习效率随温度的上升而下降。研究比较了波士顿大学学生在2016年热浪期间的表现,发现在没有空调的房间的学生在算术测试中的反应时间比有空调的同学慢了 13%,正确率也少了近 10%。极端高温导致的认知能力下降也会影响职场表现。2006 年进行的一项研究发现,在约 22℃ 的温度下,生产力最高。而当温度高出 8℃ 时,生产力水平会降低近 9%。气温升高还会降低喜悦或幸福等积极情绪,同时会增加愤怒或压力等消极情绪。

That growth environment will include rising inflation and interest rates. Those upward shifts naturally accompany healthy growth periods as the demand for resources, products and services rise. Importantly, the Federal Reserve has laid out the rationale for not interfering with that natural growth transition.It's not exactly a fad, but there is a widespread willingness to pay up for a growth story. Classic fundamental analysis takes a back seat. Even negative earnings are ignored. In fact, positive earnings seem to be a limiting measure, producing the question, "Is that all you've got?" The preference is a vision of untold riches when the exciting story plays out as expected.
