Does yawning increase hormone levels

Yawning itself does not directly increase hormone levels; however, it can be associated with various physiological changes in the body that may influence hormone release. For example, yawning often occurs during transitions between sleep and wakefulness, which can affect hormones like cortisol, dopamine, and oxytocin. Additionally, yawning may help regulate brain temperature and promote alertness, indirectly impacting hormonal balance. Overall, while yawning may coincide with hormonal fluctuations, it is not a direct cause of increased hormone levels.
