A break is an interruption of an activity - I would say. This means I interrupt or allow myself to be interrupted in what I am doing. It is not the end of the activity, but a stop, a turning to something else before continuing with the activity I have started. We know the saying "take a break" or there was a well-known advertisement that said that the best breaks have a certain colour, namely purple. Be that as it may. This expresses the fact that we cannot simply work through or "activate". Interruptions help us to recover, perhaps also to concentrate again. They are good for body and soul and spirit. The industry has also understood this and offers a wide range of food and distraction for a special break. Either way: with a break you do something good for yourself and also testify that at that moment nothing is as important to you as yourself. That seems like good self-care to me.
I wish you an extraordinary day!
