Have you ever been in a situation where you've taken a 10-minute nap and then feel completely refreshed? In fact, whatever you fell asleep to is still playing the same episode on your streaming service of choice. It's not uncommon to oversleep when it comes to taking naps, of course, but I find myself the most refreshed the lesser amount of time of the duration of my nap.
Similarly, I've often found myself literally just crying for 10 minutes - even when I'm not particularly upset about one thing as a whole, and at the end, I am able to just feel the weight off my chest. In my opinion, focusing on that emotion entirely in that moment lets you come to terms with it. This may result from being literally just too busy to allow yourself a normal amount of time to process your stress and various emotions. Even thinking about it more mindfully - you as a person are finally allowing yourself this moment of weakness. The same principle applies to sleep. Your body physically needs to chill out for ten minutes, and at that moment, you're not thinking about what items on your to-do list need to be accomplished, instead, you just sleep. Understanding what your body or emotions need at that moment, and allowing yourself just 10 minutes can make all the difference - especially when it comes to physically feel better, and feeling more composure to move forward.
This mindset doesn't have to apply to negative emotions excessively either - even happy emotions can tend to be experienced in a similar manner. For example, if I find myself receiving good news or something else happens to put me in a good mood, I personally find myself texting the people I love to share the news, and taking a couple of minutes to chill out to music and reflect upon how happy or proud of myself I feel for a few minutes - and then moving on with my day. But taking those few minutes out to just purely process my emotions and nothing else helps me pace myself out for the rest of the day.
