I sleep too much

I am a 20-year-old undergraduate who is very active in sports and other social activities on the campus. My problem is that every time I want to study, I just fall asleep. The problem is seriously affecting my work. Please help me.

Although at 20 you should be physically strong to handle many activities, however, from your question, it is most likely that you are overstretching yourself with your sporting and other social activities. The solution is for you to reduce all these activities and take more rest so that you will stop falling asleep during your studies.
