Strange when I study

At night, I never feel sleepy when I watch a movie or playing PC games. However, I will be yawning and feeling very sleepy when I am studying, what's the problem please? Why is it only when I am studying that I feel sleepy?
Thanks in advance.

This is simply because you are not interested in studying.
Thank you.
