Second, cortisol starts cross-reacting with mineralocorticoid receptors, which normally only binds a related steroid hormone - mineralocorticoids which are secreted from the zona glomerulosa layer of the adrenal cortex.

第二，醇对激素受体产生交叉反应；此类受体一般只与一种相关类固醇激素结合，即从肾上腺球状带层分泌激素。

In other words, because the cortisol is structurally similar to mineralocorticoid, it can bind to that receptor and it can trigger the mineralocorticoid effect - which is mainly to increase blood pressure by retaining fluid.

换一种说法就是，醇和激素结构相似，因此可以和受体结合并且触发激素作用，通过保持体液量让血压上升。
