Secrets To Never Getting Sick不生病的小秘密

放松打败感冒Relaxation Fights Off Colds

There are a trillion reasons why taking time tochill out might be the last item on your to-do list. But here's why it should be a priority: Being stressed will increase your susceptibility to catching acold. That may be because, over the long term, it leads to the ongoing releaseof stress hormones, such as glucocorticoids.

你肯定很奇怪，预防生病为什么要花时间来舒缓情绪？你肯定有各种借口拖拖拉拉不想做这件事。让我来告诉你为什么放松情绪要优先考虑：因为压力太大会让你很容易得感冒。这也许是因为，长期的压力过大会造成身体持续释放糖皮质激素（肾上腺皮质素）等压力荷尔蒙。

These impede your body's ability to producecell-signaling molecules called cytokines, which trigger a disease-fighting response from your immune system. You're also less likely to take care of yourself -- get ample sleep, eat right, exercise -- when you're stressed.

这些压力荷尔蒙会阻碍身体释放一种叫做“细胞因子”的细胞信号分子，而正是这些细胞因子能刺激身体免疫系统做出抗病应激反应。而且当你压力过大的时候你也不太愿意照顾自己：不会有充足的睡眠，不好好吃饭，也不愿意运动。
