Humming in and of itself is not necessarily a good or bad habit, as it is an innate action that many people do instinctively. However, it can be considered a distracting habit in professional or educational settings if it becomes a persistent behavior. On the other hand, humming can be beneficial for mental well-being and potentially for physical health as well, as it can help release tension and promote relaxation. But overall, whether humming is a good habit or not depends on the context and the circumstances.
