<p>Lol at the people saying to get more sleep. I understand everyone is different but I can literally pay attention in class with 5 hours of sleep compared to the OP 7 hours. </p>
<p>I think it’s a matter of YOU paying attention. Like one time I fell asleep but only because I wasn’t honestly paying attention. I remember a teacher in high school who have a boring voice and kinda make people fall asleep. That could be a factor like @sweetlacecharm kinda said. </p>
<p>Is this a class where you can take notes? If you just focus on notetaking that would prevent you from dozing off. You claim this happen during the winter… This is gonna seem like a random throw in the dark but maybe you’re not “active” enough? For me, because it’s cold I feel a bit sluggish compared to the spring time. It could be a weather affect. But then you mention warm classroom. So you’re probably feeling very comfy and just want to relax a bit to much. Some of my friends play low music in the ear to say up and you’ll honestly be paying “half-attention” to the profs. But I did it once for this prof and it kinda kept me up. I kinda didn’t get the prof but I did manage to get the note and some of what the prof said.</p>
