Dear, this is because you played the harmonica and caused local hypoxia in the brain, causing dizziness and other phenomena. As for skipping breakfast as you mentioned, generally speaking, the human body eats a lot of sugar every day, and some of it is consumed. Some of it becomes glycogen and is stored in the liver. When you skip breakfast, the sugar content in the blood decreases. Nervous and humoral regulation prompts the pancreas to secrete glucagon, which increases the sugar content in the blood. Maintain normal life activities, but skipping breakfast is still not good for the body. It is recommended to eat a little bit, dear, adopt it!
