Sleep is not a detail, it is a marker of health. In the Nordic countries, public-system waits for a sleep work-up can stretch, while you already track your nights with a connected ring or watch. But these devices measure trends, they do not make a medical diagnosis. A fast and structured sleep work-up, with data you own, turns those signals into decisions.
What sleep says about your health
Duration matters. A 2025 meta-analysis shows that short sleep, under 7 hours, comes with about a 14 percent higher mortality, and long sleep, 9 hours or more, with about 34 percent, compared with 7 to 8 hours. On the cerebrovascular side, insufficient sleep is associated with an increased risk of stroke. These are not numbers to feel guilty about, but to situate, a work-up helps you understand what your nights really mean.
Sleep apnea, beyond snoring
Obstructive sleep apnea is not just about noise. A 2025 meta-analysis shows it is associated with roughly 1.8 times the risk of cardiovascular events, with a dose-dependent relationship by severity. The point is to diagnose it early and treat the forms that warrant it, rather than let it progress silently.
A connected device does not replace a diagnosis
Your ring or watch are excellent tools for engagement and for tracking trends. But a 2025 meta-analysis in the Journal of Clinical Sleep Medicine shows that wrist-worn devices differ from polysomnography, the reference, over or underestimating some durations and stages. The right approach is not to oppose the two, it is to use your connected data as a signal, then confirm it with a medical-grade work-up. Your data, your dashboard, an interpretation by physicians.
What a modern sleep work-up covers
A structured work-up can combine a home sleep apnea test, polysomnography if indicated, and an insomnia assessment, for which cognitive behavioral therapy is the first-line treatment. The aim is a clear picture and usable data. Some situations call for not waiting, for example severe daytime sleepiness with a driving risk, or cardiac or neurological signs, for which you should seek care without delay.
Who benefits most from this work-up
Wherever you are, if access to a complete specialist assessment is slow, fragmented or uncertain, this work-up gives you a clear answer and a plan in 24 to 48 hours, in a single episode of care and at a European standard, rather than weeks of waiting and scattered appointments.
The NoriaHealth pathway
Speed first, an acknowledgment within 4 hours and a full sleep work-up in 24 to 48 hours. You are cared for by nos medecins a Bruxelles, a large network of specialists recognized for the quality of their facility. If a procedure is warranted, it is planned within 7 days. Follow-up is structured at day 14, 30 and 90, with a non-diagnostic connected follow-up, interpreted by physicians, and a dashboard you keep control of. Logistics come last.
Frequently asked questions
Is my connected device enough for a diagnosis ? No, it is very useful for tracking trends, but it does not replace a medical-grade work-up, which alone makes the diagnosis.
How long should I sleep ? The optimum is around 7 to 8 hours, sleeping markedly less or markedly more is associated with more risk.
Is apnea dangerous if I just feel tired ? Tiredness is a signal, untreated apnea is associated with excess cardiovascular risk that rises with severity.
Is a full sleep work-up in 48 hours realistic from Scandinavia ? Yes, it is the heart of our promise, with care afterward if needed.
Describe your sleep symptoms and share your connected data if you wish, reply within 4 hours, full work-up in 24 to 48 hours.
Passing it on to someone close
You may be reading this for someone else, a relative, a parent, a colleague. If this can help someone close to you get a clear and fast answer, feel free to pass it on, it is often the first step that is missing.
