Can Sleep Apnoea Cause Depression and Anxiety?
When Sleep Affects Mental Health
Many people think of sleep apnoea as a breathing problem. In reality, it can have a significant impact on emotional wellbeing.
What Happens During the Night?
A person with untreated sleep apnoea may experience:
- Hundreds of breathing interruptions
- Repeated oxygen desaturations
- Frequent awakenings
- Poor sleep quality
The brain never reaches the restorative sleep it needs.
Common Mental Health Symptoms
Untreated sleep apnoea may contribute to:
- Irritability
- Depression
- Anxiety
- Memory difficulties
- Reduced concentration
- Emotional exhaustion
Many people report feeling mentally “foggy” long before they recognise they have a sleep disorder.
Why a Sleep Assessment Matters
Not all depression or anxiety is caused by sleep disorders, but untreated sleep problems may make mental health symptoms worse.
A sleep study can identify whether disrupted sleep is contributing to the problem.
