According to some religions, Saturday is considered to be the Sabbath Day, the day of rest. Most Christians believe that Sunday is the reserved day. Regardless of what day it is, I believe we should set aside one day during the week to rest and recharge.
I would normally write a detailed blog explaining why we need to understand or consider doing something. In this case, however, I believe you already know the reason. You, in particular your body, are the only one that determine whether you need to rest or not. So, the only advice I will give you is for you to listen to your body. If you don’t have any urgent matters to attend to, and you feel drained or unmotivated, recharge by taking a day for yourself to rest and lay around in your bed, like I do from time to time. 🙂
