If you sleep enough hours and still wake unrefreshed, this is the possibility worth ruling out before anything else.
What it is
Obstructive sleep apnoea involves repeated partial or complete collapse of the upper airway during sleep, causing breathing pauses, oxygen desaturation and brief arousals that fragment sleep without producing full awakening. Severity is measured by the apnoea-hypopnoea index, the number of events per hour. It is common and substantially underdiagnosed, partly because the person affected is asleep for all of it.
The signs
Loud snoring, witnessed breathing pauses, gasping or choking arousals. Waking unrefreshed despite adequate time in bed. Excessive daytime sleepiness, including falling asleep in passive situations. Morning headache. Nocturia. Difficulty concentrating and memory complaints. Risk factors include obesity, male sex, increasing age, large neck circumference, certain craniofacial features and menopause. Notably, it occurs in people who are not overweight and in women, both of which contribute to underdiagnosis.

Untreated apnoea is associated with hypertension, cardiovascular disease, metabolic dysfunction and accident risk from daytime sleepiness. Cognitively, sleep fragmentation and intermittent hypoxia are both implicated, and associations with cognitive impairment and dementia risk have been reported. Diagnosis requires a sleep study, increasingly available as a home test. Treatment options include CPAP, mandibular advancement devices, positional therapy and weight management. This is a medical matter, not a supplement one.
Key takeaways
- Arousals fragment sleep without producing full awakening
- It occurs in people who are not overweight and in women, contributing to underdiagnosis
- Sleep fragmentation and intermittent hypoxia are both cognitively implicated
- Home sleep testing has made diagnosis considerably more accessible
