Yawning after 8 hours of sleep can be attributed to several factors, including the body's need to increase oxygen intake and regulate brain temperature. Even after a full night's rest, yawning may signal a transition from sleep to wakefulness, helping to increase alertness. Additionally, it could be a response to boredom or a relaxing environment, prompting the body to maintain energy levels.
