Drinking a cup of tea in the morning is refreshing and enjoyable. A cup of tea before studying can refresh and sharpen your mind, helping you study more effectively. However, drinking too much tea may not be beneficial for you, so it's important to drink it in moderation. Not too much, but not too little either. I have a friend who drinks a lot of tea, and I have advised her to drink it in moderation, but she didn't listen to my advice.
