Your Jaw Can Affect Your Personality

Obstructive Sleep Apnea (OSA) has been widely linked to mood alterations such as depression, anxiety, and irritability. The physiological mechanisms behind this are multi-faceted, including decreased oxygenation levels during sleep and altered levels of hormones such as cortisol and melatonin.


Decreased oxygenation levels during OSA events can lead to hypoxia, a condition in which the body is not receiving enough oxygen to support normal physiological functions. This can lead to alterations in brain function and mood. Additionally, the stress of repeated awakenings during OSA events can increase cortisol levels and disrupt the normal circadian rhythm of hormones such as melatonin, leading to further mood alterations.



Treatment of OSA with custom orthognathic surgery can alleviate these mood alterations by resolving the underlying airway obstruction. By improving the structural alignment of the jaw, soft palate, and tongue, the airway is kept open during sleep and oxygenation levels are maintained. Additionally, by improving sleep quality, the normal circadian rhythm of hormones is restored, leading to further improvements in mood.


OSA has been shown to have a significant impact on mood, through decreased oxygenation levels and altered hormonal balance. Alfi Oral Surgery provides a comprehensive solution for OSA by resolving the underlying airway obstruction and improving sleep quality, which can lead to significant improvements in mood.
