Sleeping well over Thanksgiving comes down to two things you can control: how much you drink late in the evening, since about two standard drinks delayed and shortened REM sleep in a meta-analysis of 27 studies (Gardiner et al., 2025), and whether your pillow fits you in an unfamiliar bed. Guest rooms, hotel pillows and late nights all change the conditions your neck is used to. This article covers what the research says about a holiday evening, practical steps for guest beds and travel, what pillow height measurably changes, and how a Pillowise fitting lets you bring the same height with you.
Key takeaways
A systematic review and meta-analysis of 27 studies in healthy adults found that low-dose alcohol, about two standard drinks, delayed the onset of REM sleep and reduced REM duration, with larger effects at higher doses (Gardiner et al., 2025).
The same review found large uncertainty in the effects on total sleep time, sleep efficiency and time awake after sleep onset (Gardiner et al., 2025). The REM finding is the consistent one.
Late nights also cost sleep. In a crossover study of 14 healthy adults, one night of total sleep deprivation produced hyperalgesia to heat, cold, blunt pressure and pinprick (Schuh-Hofer et al., 2013).
A borrowed pillow sets your neck at whatever height its owner chose. On a different bed, the same pillow can also leave your head higher or lower than at home, since your shoulder sinks to a different depth.
A few practical steps for the trip:
Pillow height changes the position of the neck. In a radiographic study of 16 adults aged 20 to 30 without neck symptoms, raising pillow height from 0 to 10 to 20 cm increased T1 slope and the C2-7 Cobb angle, and the authors judged 10 cm most suitable for normal cervical lordosis in that group (Kim et al., 2015).
Height also changes load. In 10 healthy participants lying on their backs, pillow heights from 110 to 170 mm shifted cranio-cervical pressure distribution and cervical spine alignment (Ren et al., 2016).
Height changes muscle work as well. In a pilot surface EMG study of 15 adults lying on their side, sternocleidomastoid and trapezius activity differed across heights set at half, equal to, and one and a half times shoulder width (Jiao et al., 2025).
A standard contoured pillow, not fitted to the individual, performed no better than ordinary shapes in a randomized study of 106 side sleepers (Gordon et al., 2009). No single optimal pillow height can be specified, because it depends on four variables that differ from person to person: cervical alignment, body dimension, contact pressure, and muscle activity (Lei et al., 2021).

Pillowise is a fitted cervical pillow that licensed healthcare providers measure and dispense, made in seven sizes. Our sleep specialists take three measurements: shoulder width, neck circumference, and neck length. Combined with sleeping position and bed type, an algorithm identifies the best-fitting pillow from seven sizes.
Shoulder width is the measurement the EMG study found mattered most. A height matched to it produced the lowest neck and shoulder muscle activity during side sleeping (Jiao et al., 2025), and body dimension is what drives the individual optimum (Tian et al., 2025).
The Travel size is measured the same way as the Standard and Queen, so the same fit can go with you when you travel.
Pillowise pillows are made from premium Dutch memory foam and certified to OEKO-TEX Standard 100, which tests components against limits for harmful substances. Returns and exchanges are handled by Pillowise directly.
The mechanism studies behind fitting are small, with 9 to 16 healthy adults in each (Kim et al., 2015; Ren et al., 2016; Jiao et al., 2025; Tian et al., 2025). Reviews of clinical outcomes are mixed: the most recent screened 29,091 records, included five studies covering 239 patients with chronic neck pain, and found no clear advantage for any pillow type (Ghosh et al., 2025). A fitted pillow is a comfort and fit measure that works alongside clinical care, not in place of it.
Ask patients where they will sleep over Thanksgiving, whether they are driving or flying, and how they slept on their last trip.
Tell them two things the research supports: about two drinks delayed and shortened REM sleep (Gardiner et al., 2025), and pillow height changes neck alignment and muscle activity (Kim et al., 2015; Jiao et al., 2025). Then suggest they pack the pillow they were fitted for.
A fitted pillow extends the work of the visit into the hours between visits, alongside the exercise, manual therapy, and other care you are already delivering.
It affects REM sleep. In a meta-analysis of 27 studies, about two standard drinks delayed REM onset and reduced REM duration, with larger effects at higher doses (Gardiner et al., 2025). Effects on total sleep time and night waking were uncertain in the same review.
If your pillow was fitted to you, bringing it keeps your neck at the height chosen in your fitting. No single optimal height can be specified for everyone (Lei et al., 2021), and a host's pillow was not chosen for you.
A full night without sleep did in a laboratory study: 14 healthy adults became more sensitive to heat, cold, pressure and pinprick (Schuh-Hofer et al., 2013). A short night is less extreme than the study condition.
Not reliably. A standard contoured pillow, not fitted to the individual, performed no better than ordinary shapes in a randomized study of 106 side sleepers (Gordon et al., 2009), and no single optimal height can be specified because it depends on four variables that differ from person to person (Lei et al., 2021). A contour helps only if its height matches the person using it. That is what the fitting settles, in a provider's office.
Pillowise pillows are clinically measured and dispensed exclusively through licensed healthcare providers as part of broader sleep, posture, and recovery education.
