The 30-day sleep study

Most sleep tests record one or two nights. We follow your sleep at home, every night for up to 30 days, so your plan is built on how you really sleep.

Our 30-day sleep study

Real-time sleep tracking with the Empower device

Most sleep tests capture one or two nights in an unfamiliar bed. With the Empower device, you wear a small sensor on your finger at home, every night for up to 30 days, and results are available after each night.

  • A true baseline, built from many nights rather than one
  • Each change we make, such as breathwork, a new routine, weight loss or treatment, is tracked night by night
  • Your plan is adjusted as we go, based on what your sleep data shows
  • Measures sleep quality and sleep stages, and screens for sleep apnoea and disturbed breathing
  • Every result is reviewed with you by a Levitas clinician

The device uses SleepImage technology, which is CE marked as a medical device.

Your journey

How Levitas Sleep works

  1. Step 1

    Consultation

    Full sleep and medical history, validated questionnaires and a review of medicines, alcohol, caffeine and screens.

  2. Step 2

    Testing

    Empower 30-day home sleep study with results after every night, a sleep diary and targeted blood tests.

  3. Step 3

    Airway check

    Dental and airway assessment where snoring, apnoea or mouth breathing is suspected.

  4. Step 4

    Your plan

    Results reviewed with you and a personalised, evidence-led sleep plan.

  5. Step 5

    Follow-up

    Reviews at four to six weeks and three months, using your night-by-night sleep data to show what is working.

Blood tests may include ferritin and iron studies, thyroid, vitamin D, B12, HbA1c, hsCRP and hormones (oestradiol, progesterone, testosterone, cortisol) where indicated. Consumer wearables such as Oura and Whoop are useful for trends, but they are not diagnostic. We refer for full hospital polysomnography where needed.
