  1. If it's really about the brain, I've never seen any research on it. If you say that it is easier for you to study at night or that you have more energy, especially when there is a feeling or specific knowledge (I do not know if you live alone or not) that everyone around you has already fallen asleep, then this often indicates psychological problems of the widest range. There are still a thousand questions to clarify: was it always like this, if not, when it started, after what event, what became disliked, and so on. The current reality can put some pressure on the psyche, it extinguishes energy and activity increases when everything disappears. Someone has an excessively large sense of responsibility and the night removes it. Someone has depression/rejection of reality and then the body goes into the night, opposing itself to sunlight/happiness and all that. The list of answers to this question is huge and you can't understand it without more information.

  2. Well, probably because it is low during the day.: -). A person is a rhythmic being. And brain activity is no exception. Another question is that everyone has their own biorhythms, as a result of planning their day and being passionate about gadgets. Yes, it is gadgets. There are studies that confirm that as a result of active viewing in devices where the image is formed due to radiation into the human eye, there is a strong irritation of the ocular nerve. As a result, general irritability and “difficulty falling asleep”, which can be interpreted as “nocturnal activity”. This is the first one.

    Second. If you are already used to sleeping during the day and working at night, then your body will adapt to this. And so it can really be a situation that the brain activity is higher at night, because it “rests” during the day. But at the same time, your fatigue will be higher, because such rhythms are unnatural for the human body.
