Its very important to learn yom v Lelaih, however one must also be careful not to suffer from burnout (I have unfortunalty seen this happen).
Taking a break from learning in order to recharge your batteries is a healthy idea and closing a gemorah in order to learn mussor is not a “break”
One should see alternatives to allow one to recharge and take a break with things that are kosher or pareve (Fully kosher activities might not be available so Pareve ones are good too)
