Does yawning make you sleepy or more awake?

Yawning is often associated with both sleepiness and the body's response to increase alertness. It can occur when you're tired, signaling the brain to prepare for rest, but it can also help increase oxygen intake and regulate brain temperature, potentially making you feel more awake. Overall, yawning serves multiple purposes, acting as a cue for both relaxation and alertness depending on the context.
