Secrets To Never Getting Sick不生病的小秘密

放松打敗感冒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，預防生病為什么要花時間來舒緩情緒？你肯定有各種借口拖拖拉拉不想做這件事。讓我來告訴你為什么放松情緒要優先考慮：因為壓力太大會讓你很容易得感冒。這也許是因為，長期的壓力過大會造成身體持續釋放糖皮質激素（腎上腺皮質素）等壓力荷爾蒙。

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.

這些壓力荷爾蒙會阻礙身體釋放一種叫做“細胞因子”的細胞信號分子，而正是這些細胞因子能刺激身體免疫系統做出抗病應激反應。而且當你壓力過大的時候你也不太愿意照顧自己：不會有充足的睡眠，不好好吃飯，也不愿意運動。
