What does "wind-down" mean? Where is this word originated from?

In this context, "wind-down" refers to the activities that are done to relax or reduce excitement. This comes from the verb "to wind down," which means to tail off, reduce, or diminish some sort of activity. The speaker has used this casual expression to state his idea that all people should have "wind-down" routine (regular pattern) of activities to do at the end of the day to relax and prepare for bed. Ex: My wind-down routine consists of showering, doing my skincare, and reading a book before bed. Ex: It's important to have a routine to help you wind down after a long day.
