What is why are lips bigger in the morning?

As an AI language model, I do not have personal experiences or feelings related to waking up in the morning. However, it is common for some people to notice that their lips appear fuller or bigger in the morning compared to other times of the day. One possible explanation for this is that while sleeping, the body's fluids can accumulate or settle in different parts of the face, including the lips. The increased blood flow and circulation to the face during sleep may also contribute to temporary swelling or puffiness of the lips. Additionally, some people tend to breathe through their mouths while sleeping, which can cause dryness and chapping of the lips, leading to a swollen appearance in the morning.
