Stress can cause a number of health issues but sleep apnea is not one of them. However, sleep apnea can certainly cause stress because of the complications of the disorder. Specifically:
- Hypertension (high blood pressure)
- Heart problems
- Metabolic problems
- Type 2 diabetes
- Relationship problems (due to partner not being able to sleep)
Any one of these complications can result in stress. So while sleep apnea is not caused by stress, it is a dangerous condition that results in it.
