Nature子刊说,度个假就能改变基因活性,或许还能更长寿?

2016-10-01 MedSci MedSci原创

在一项新研究中,研究人员分析了闭关冥想和简单放松对人体压力调节、免疫功能及血液中细胞标志物的影响,他们以度假女性为研究对象,检测其在度假期间及后几个月内的基因活性和血液标记物的变化,结果发现了所有参与者都呈现出一个巨大而直接的假期效应。对于那些有冥想训练习惯的人来说,这种效应在10个月后仍然能检测到。相关结果报道在《Translational Psychiatry》杂志上。简单的度假,就能改变基因

在一项新研究中,研究人员分析了闭关冥想和简单放松对人体压力调节、免疫功能及血液中细胞标志物的影响,他们以度假女性为研究对象,检测其在度假期间及后几个月内的基因活性和血液标记物的变化,结果发现了所有参与者都呈现出一个巨大而直接的假期效应。对于那些有冥想训练习惯的人来说,这种效应在10个月后仍然能检测到。相关结果报道在《Translational Psychiatry》杂志上。

简单的度假,就能改变基因活性

该研究招募了102名30至60岁的非禅修女性,这些女性均进行了为期五天的度假。在这些参与者中,大约三分之一有过定期冥想训练,剩下的70%没有过这种训练史。

研究人员将102名女性分为三组:长期训练组(有冥想训练史的女性,度假期间坚持进行冥想和瑜伽训练)、度假+训练组(将没有冥想训练史的女性随机分配,度假期间接受瑜伽和冥想训练)、单纯度假组(将没有冥想训练史的女性随机分配,度假期间不接受任何训练)。

研究人员对这三组女性的血液进行分析,血液采集时间为度假期间、度假后1个月以及度假后10个月。此外,参与者还汇报了整个研究周期中自身的抑郁症状、压力状况、活力以及注意力等。

调查结果发现,度假期间及假期后的1个月中,三组女性的心理健康评分都有改善。十个月后,与只度假的人相比,在假期中参加训练的人抑郁症状和压力减小的幅度要大些。在假期末期,三组人员的基因表达和衰老生物标志物都有了很大的改变,这表明了简单的度假带来的好处。此外,那些定期冥想的女性有较高的端粒酶活性。

度假+冥想,能延长寿命?

本文资深作者,纽约伊坎基因组学和多尺度生物学研究所(Icahn Institute for Genomics and Multiscale Biology at Mount Sinai)Eric Schadt博士说,“一个放松的假期环境,可以让人远离压力,使身体卸下多种防守姿态,这反过来又会影响机体中与免疫系统相关的细胞的活性。”

他指出,对于冥想组,在分子水平上发生的额外变化只会更多,包括更加有效地制造和利用蛋白。“我们不知道这意味这什么,但鉴于与衰老的生物标志物有关联,我们认为这些变化很有可能提高机体的健康和长寿水平。”

Schadt说,“假期和冥想似乎能抵抗免疫反应和炎症反应。如果这些反应能抵抗疾病,那么人们当然希望它能激活,但如果这些反应不断被激活,那么可能会增加一系列疾病的易感性,包括糖尿病、老年痴呆症、自身免疫性疾病等。”

不过,研究人员也承认,该研究规模比较小,结果或许还不足以证实这些变化对疾病或人体长寿的影响。“但我们的研究为放松和冥想能产生健康效益提供了强有力的证据。”

未参与该研究的麦克马斯特大学Guillaume Pare博士说,“毫无疑问,减少压力有益健康,它至少能带来更好的健康结果。然而仍需大量的研究来证实该研究中的因果关系——特定的基因及途径与人体健康的关联性。”
