Takeaway
Quality of sleep is compromised in individuals with episodic and chronic cluster headache (ECH/CCH), potentially because onset tends to occur in the early hours of the morning.
People with CCH find it difficult to adjust sleep patterns, while those with ECH are less able to cope with decreased sleep duration.
Why this matters
Clinicians should advise people with episodic and chronic migraine to adhere to individualized, regimented sleep schedules as it may help to prevent headache.
