Digital CBT-I in Pregnancy: Four Trial Checks

Bring a record of your difficult nights to your next maternity appointment. Include how you feel during the day and what you already use for sleep. If you are considering a digital insomnia program, discuss these four questions before starting it.

Who took part?

Felder’s trial randomized 208 women at most 28 weeks pregnant. Most were white, wealthy and college educated. Eligibility included elevated symptoms without requiring a chronic-insomnia diagnosis. Only 68/105 assigned Sleepio completed all six weekly sessions, each about 20 minutes. Access vouchers came from the manufacturer; researchers disclosed other industry ties.¹

What improved?

Over ten weeks, the between-group difference in weekly Insomnia Severity Index change was −0.36 points (95% CI −0.48 to −0.23). Outcomes were self-reported; usual care provided no matched attention control. Sleep duration did not differ significantly (P=.07).¹

The NHS² advises speaking to a doctor or midwife when lack of sleep is troubling you. Explain whether you struggle to fall asleep, wake repeatedly or feel unable to manage the following day. Ask what further assessment is appropriate.²

What about pregnancy safety?

The digital group reported three miscarriages, classified possibly related; one preceded program use. Usual care reported two miscarriages and one stillbirth, classified unrelated. These small counts cannot establish infant safety or show that the program caused pregnancy loss.¹

The manufacturer’s legacy Sleepio web-version suitability information advises doctor review during or after pregnancy. It warns that restricting time in bed can temporarily increase daytime sleepiness and that nighttime getting-up instructions can increase fall risk. Mention excessive sleepiness, bipolar disorder, seizures or untreated sleep apnea before treatment. This page describes web version 2.0.0, rather than a complete current US prescribing assessment.³

Which product and plan are being offered?

The trial used legacy Sleepio during 2016–2018.¹

Current US SleepioRx is a prescription device for adults aged 18 or older with chronic insomnia or insomnia disorder, alongside usual care. The FDA-cleared indication requires a licensed healthcare provider’s order. That adult indication should not be read as proof of safety for every pregnancy. Ask the prescriber to check the exact version’s current instructions, your pregnancy circumstances and who will supervise any changes to time in bed.⁴⁵

Do not build your own sleep-restriction timetable from an article. Ask how daytime sleepiness, nighttime bathroom trips and changing pregnancy needs will be handled. The manufacturer’s legacy guidance calls for individual medical review; it does not replace maternity care.³

Also tell your doctor or midwife about hopelessness or losing interest in things you previously enjoyed. The NHS² identifies these as reasons to discuss possible depression when sleeplessness accompanies them. Its pregnancy guidance also suggests asking the midwife about relaxation techniques.²

Did I Do That in My Sleep? explains “What CBT-I Actually Addresses” and “Getting Access.” Those sections distinguish structured insomnia treatment from a meditation library and cover questions about provider training, digital access and supervision. Take those questions to the appointment when deciding whether a particular program fits your care.
