Hypnic headache is a rare primary headache disorder that is characterized by exclusively sleep-related headache attacks in patients usually beyond 50 years of age. Only 174 cases have been reported in the literature so far. Owing to its low prevalence, clinical features and therapeutic options, as well as underlying pathophysiologic mechanisms, are widely unknown or being controversially discussed. The association of hypnic headache with rapid-eye movement sleep was strongly contradicted in…

It is suggested that 24 h ambulatory blood pressure monitoring may be included in the evaluation of nocturnal headache complaints especially in the elderly, in whom essential hypertension is a very frequent comorbidity.
Hypnic Headache: Another Indomethacin‐Responsive Headache Syndrome?

Hypnic headache: an update
TLDR
Sufficient evidence, mainly from polysomnographic studies, indicates that HH is a primary rapid eye movement (REM) sleep-related headache disorder of chronobiological origin and Lithium, melatonin, indomethacin and caffeine at bedtime are among the most effective therapeutic options.

TLDR
There is growing evidence that cluster headache and hypnic headache are chronobiological disorders that have an indirect impact on the sleep-wake cycle.
