What is Self-Soothing Practice?

n = 42

Finding: In a small single-blind trial, 42 mother-infant pairs were split into two groups, and the parents in one group were taught four structured soothing moves: swaddling, holding the baby on their side or stomach, shushing or white noise, and gentle swinging. Compared with the untrained group, infants whose caregivers used these techniques woke less often at night, cried for shorter stretches, and slept longer during the day across repeated check-ins over the following months. This points to something worth knowing for anyone drawn to self-soothing: structured, physical sensory input can genuinely calm distress and settle an overstimulated nervous system. Keep in mind, though, that this study looked at babies being soothed by a caregiver, not adults using sensory tools on themselves, so it supports the underlying idea more than it proves the adult practice.

n = 80

Finding: Following 80 infants who slept on their own across their first year, this study found that giving them a new soothing object did little to change how they slept or how well they settled themselves back to sleep. What actually predicted stronger self-soothing at 12 months were everyday circumstances rather than any single prop: spending less time being lifted out of the crib, sleeping quietly from birth, and having parents who waited a little longer before responding overnight. The takeaway is that the ability to self-soothe seems to grow out of many small contextual factors, not from one special aid, so it's worth being skeptical of claims that a particular object reliably builds it. Keep in mind this was research on infants, so it speaks only indirectly to adults practising deliberate self-soothing techniques.

2024

Finding: Following 150 mothers and their babies in Germany at three and seven months old, this observational study compared two ways of calming an infant: "close" soothing built on physical and emotional contact, and "distant" soothing that keeps more space. Babies soothed with warm, contact-based comfort settled more easily and regulated their crying and sleep better over the following months, which fits the idea that being calmed by someone else early on helps build the capacity to self-calm later. For an adult exploring self-soothing, this hints at why warm, sensory comfort may matter, but the study looked only at caregivers calming infants, not at adults soothing themselves, so it is background support rather than direct proof that the practice works for you.

2020

Finding: This study looked at "maladaptive daydreaming," an absorbing, hard-to-control retreat into vivid fantasy that people often lean on to manage distress, and how it changed when the COVID-19 pandemic forced many into isolation and quarantine. It offers a window into how people reach for inner coping strategies under prolonged stress, which is part of why it sits in the background of a self-soothing practice. It does not test the sensory self-soothing techniques themselves, though, so it can't tell you how well those specific tools work. Treat it as helpful context on distress and coping rather than direct proof that this practice delivers a particular result.

2018

Finding: This study looks at maladaptive daydreaming, a pattern in which people become absorbed in vivid, hours-long fantasies that pull them away from relationships and responsibilities and leave them genuinely distressed. It helps define and take seriously the very experience that a self-soothing practice might one day help with, rather than testing the practice itself. Because the specific outcomes and effect sizes for any technique were not reported here, treat this as background on the problem, not as evidence that self-soothing resolves it.

n = 5,006

Finding: In a large online survey of more than 5,000 parents of children from birth to age three, babies whose bedtime routines gave them room to settle themselves slept for longer, less broken stretches, while those who relied more on active parental intervention to fall asleep tended to wake more often. For a practitioner, this hints that letting the body find its own way back to calm may support more settled rest. Keep in mind, though, that this was an observational study in infants, so it points to a pattern rather than proving cause, and it does not test the adult sensory self-soothing technique itself.

n = 69

Finding: When 69 young infants were soothed with a combination of swaddling, sound, and gentle movement, they calmed quickly: they fussed less and their heart rates dropped compared with a distressing period of lying flat. A measure of nervous-system flexibility (heart-rate variability) tended to rise during soothing but did not shift reliably, so the calming effect showed up more clearly in visible distress and heart rate than in that deeper autonomic marker. This is a promising hint that gentle sensory input can settle the body, but the study looked at babies being soothed by others, not adults soothing themselves, so it can only suggest, not confirm, what the practice does for grown-ups.

2021

Finding: This study looked at how people coped emotionally during the COVID-19 pandemic, focusing on compulsive, immersive daydreaming, a habit of retreating into vivid fantasy that tends to go hand in hand with distress rather than relief. It examined how that pattern related to depression, anxiety, and stress during a period of major upheaval, so it maps the terrain of unhelpful coping more than it tests any calming technique. Because no specific results or effect sizes are available here, it is best read as a snapshot of one stressful moment rather than proof that any particular self-soothing routine helps. If you notice yourself drifting into escapist daydreams when overwhelmed, that may be a signal to reach for a grounded, deliberate soothing practice instead.
