If your nights sound like this, go

The study is the right next step when the question is what your body is doing during sleep. The tell-tale pattern is that you sleep — often heavily — and still wake unrefreshed, and that the people around you notice more than you do:

• A partner or family member has heard you stop breathing, choke, or snort awake
• Snoring loud enough that it has come up in conversation, or moved someone to another room
• Mornings that begin with a dry mouth or a dull headache
• Sleepiness you cannot argue with: nodding off at a red light, in church, or in the middle of a sentence
• Blood pressure that stays high despite treatment, especially alongside the signs above
• Kicking, thrashing, or acting out dreams hard enough to bruise or wake someone

Those are the fingerprints of a physiological sleep disorder — most often obstructive sleep apnea — and they justify the test. Keep the appointment.

If your nights sound like this, the study will probably come back normal

The other pattern is the one we treat all day in Virginia, and it produces a surprising number of normal sleep studies every year:

• Getting to sleep takes an hour, or you drop off fine and then surface at 3 or 4 am for good
• The moment the light goes off your mind starts running tomorrow's meeting, yesterday's conversation, next month's bills
• You are exhausted but oddly alert — you could not fall asleep in a waiting room if you tried
• You sleep better in a hotel, on the sofa, or on the nights you have stopped caring
• Nobody has ever mentioned your breathing, and you do not wake gasping

That is chronic insomnia. The diagnosis rests on your account of your nights and a week of sleep diary, not on sensors, and the professional guidelines do not call for a sleep study to make the diagnosis. The treatment with the strongest evidence is Cognitive Behavioral Therapy for Insomnia, which is what our clinicians deliver — see our insomnia treatment page for how the course runs.

When it is both

Sleep apnea and insomnia often occur together — treated apnea with a mind that still will not switch off is one of the commonest pictures we see. We treat the insomnia, we have partners who treat the apnea, and your clinician coordinates any referral that is needed. In practice that means the referral runs through your own primary care doctor, who orders the test and holds the result, while your Virginia Sleep Center clinician writes to them with what the evaluation found and carries on with the insomnia work. You are not asked to choose between the two problems.

What Virginians tell us after a normal study

A recognisable share of our first appointments begin with a printout: an overnight study, a normal apnea index, a note that says "no significant findings", and a patient who feels quietly dismissed by it. What our clinicians hear next is nearly always the same — relief that nothing is physically wrong, followed by "so why can't I sleep?". A normal study is not the end of the road. It has ruled out the things a sensor can see and left the thing it cannot, and that thing has a structured, medication-free treatment with a good track record. Bring the printout to your evaluation; it saves a step.
