4. Morning Headaches: The Unwelcomed Alarm Clock
The pounding head, the pressure behind the eyes, the desire to retreat into darkness – OSA-induced morning headaches are a world of their own. Due to the repeated drops in oxygen levels throughout the night, blood vessels in the brain dilate. This vascular response causes tension in the brain, manifesting as a throbbing headache upon waking.
Unlike regular headaches that might dissipate with time, OSA-induced morning headaches can persist for hours, casting a shadow over the entire day. The intensity can range from mild discomfort to severe pain, making even routine tasks daunting.
While the primary cause of these headaches is the oxygen level drop, other factors contribute to their occurrence. The constant awakenings prevent the necessary relaxation of muscles during sleep, causing tension around the neck and head. Additionally, frequent nighttime trips to the bathroom (another OSA symptom) can lead to dehydration, which in itself can be a headache trigger.
An occasional morning headache might not raise eyebrows, but if it becomes a regular occurrence, especially in conjunction with other OSA symptoms, it’s cause for concern. Tracking the frequency and intensity of these headaches can provide valuable insights for a healthcare provider and lead to an OSA diagnosis. (4)
