Why do I feel dizzy and sleepy when I practice breathing and breathing? I hope to know the explanation.

I have a similar feeling. Excessive yang and insufficient yin. Temporarily forget the achievement method, try to put it down (not press).

This phenomenon may be caused by blindly following the achievement method and not letting nature take its course.

Because you missed the rhythm when you practiced. It's time to put it down and put it up. You are really sleepy. Don't think about martial arts when you sleep. You must practice when you are awake, otherwise there will be more serious problems than the above problems.

Be sure to concentrate, hold your breath, stay calm and try not to practice in noisy places. It's dangerous to be afraid when practicing.

Generally speaking, when practicing blindly, there should be pressure to lift and lower. Most people who have just practiced lack confidence. Because they couldn't catch the sinking breath at first, they didn't dare to let go, and the problem was solved to some extent.
