来自佛罗里达州立大学的一项新的研究显示,枯燥的、不洁的工作环境或可损害员工的长期认知健康,该研究已发表于 Journal of Occupational and Environmental Medicine。

当谈到记忆和思维能力,既往研究已表明,职业或可显著影响大脑的记忆和思维能力。如2014年发表的一项研究表明,职业倦怠——身体、情绪或精神职业枯竭——可影响机体日后的认知功能。

该研究首席研究员Joseph Grzywacz及其同事表示,

此外,还有一些研究表明,不洁的工作环境也会影响大脑长期的认知功能,还有一些研究表明,乏味的工作可影响大脑的健康。

然而,该研究人员指出,对认知健康影响最大的因素:不洁的还是枯燥的工作场所,仍存在争议。该研究表明,两者都可能发挥重要的作用。

研究人员分析了参与MIDUS研究的4963名成年人的数据(53%为女性),年龄在32-84岁之间。

收集参与者的职业信息,包括他们的就业状况,工作地点,工作的复杂性,工作场所的物理危害以及工作条件,如清洁。

使用BTACT来评估参与者的认知功能,BTACT可用于测试参与者的情景记忆,自我感知记忆和执行功能。

结果发现,与工作环境较好的员工相比,处于不洁的工作环境中工作的员工,即在工作中接触到霉菌、溶剂以及其他化学物质的员工更容易发生认知能力下降。

具体而言,在不洁环境中工作的员工其情景记忆(记忆事件的能力,如时间和地点)和执行功能较差(控制和使用更高级别认知技能的能力)。

此外,研究还发现,职业复杂性更高(有机会学习新技能并接受新的挑战)的员工较工作乏味的员工认知功能更好一些,且该关联在女性中更强一些。

从事更有激励性的工作的成年人其执行功能、情景记忆以及自我感知的记忆更好一些。

总体而言,该研究结果强调了激励性的、洁净的工作环境对员工的重要性。

最后,Joseph Grzywacz教授说道,“这里的实际问题是与衰老相关的认知下降,以及不使用它就会失去它的想法。设计工作确保所有的员工有一定的决策能力,这或可保护员工日后生活中的认知功能,同时也需要洁净的工作环境。”
