It is something that many students around the world have done, do and will do. We talk about mixing the leisure with the studies or, simply, of not giving the necessary time to our body to differentiate between the two things. We are going to present it with an example, since at first glance it could seem quite confusing.
You imagine that one night you go out to party, but the next morning you have enough time to rest and recover the lost sleep. In this situation there would be no major problems. The truly harmful It would be if we went out for a walk, went to bed late, and the next day we had to go to class. Something that would be quite harmful to our body.
Why do we say that it is not advisable to combine leisure with studies? Basically, because when we do both in the wrong way, our body is harmed in different ways, causing we can't study normally and, therefore, affecting the quality of our results.
There are not many more things to say. Combining leisure with studies is not recommended, so we strongly advise you not to do it, since you could fall into a error that you could even drag for several weeks, causing the performance of the course to drop significantly.
On the other hand, you can combine leisure with studies, but giving them the number of hours needed to each activity. In this way, our body will not be harmed. Each person needs their own time, so you will have to calculate the hours that you should dedicate to each activity.
