The cultural framing of adults who sleep in the same bed as their pets has, on the available evidence, mostly missed what the behavior is actually about. The standard interpretations tend to fall into two unhelpful categories. The first is that the adult is, in some real way, substituting the animal for human intimacy that has gone missing. The second is that the adult is performing a piece of mildly indulgent self-care that, while not harmful, is not particularly serious as a feature of adult life.
Neither of these interpretations captures, on close examination, what most adults who do this are actually doing. The behavior is, in most cases, considerably more substantive than the substituting-for-intimacy framing suggests, and considerably less indulgent than the self-care framing implies. The behavior is, more accurately, the visible feature of a particular recognition about adult relationships that most people postpone for considerably longer than they should, and that the animal in the bed is, in some real way, the most consistent daily reminder of.
What the recognition actually is
The recognition is that the relationships that work most reliably are, on close examination, the ones that do not require the person to be anyone other than who she actually is. The relationships that work less reliably, regardless of how warmly they are conducted, are the ones that ask the person, in various small ongoing ways, to perform some version of herself that is calibrated to the other party’s preferences rather than to her own actual state.
This is, by any honest accounting, a structural observation about the architecture of adult relationships, not a complaint about any particular relationship. Most adult relationships involve, by their nature, some degree of calibration to the other party. The calibration is part of how the relationships function. The calibration is also, on close examination, a small ongoing cost that the relationships exact, distributed across the thousands of small interactions that constitute the relationship’s actual texture.
The animal does not require this calibration. The animal does not, in any structural sense, have a preferred version of the person it is sleeping next to. The animal is, more accurately, attached to the actual person, in whatever state the actual person currently happens to be in. The grumpy version. The exhausted version. The version that has been crying in the bathroom. The version that has not, for three days, said anything particularly interesting to anyone. All of these versions are, in the animal’s accounting, the same person. The animal sleeps next to her regardless of which version she is currently presenting. The not-requiring-her-to-be-different is the structural feature the animal is, in some real way, the daily reminder of.
What the research says about the bond
The wider research literature has documented this dynamic from a different angle, primarily through the framework of attachment and the oxytocin system. A nationally representative study published in Scientific Reports found that nearly half of pet owners in the United States report co-sleeping with their animals. The same study, examining the effects of this co-sleeping on stress and sleep characteristics, identified the practice as serving a stress-buffering function for adults’ sleep, by reducing bedtime physiological and cognitive arousal and by serving as a source of reassurance and comfort.
The mechanism, on the available evidence, involves the oxytocin system. Physical proximity to a bonded animal produces measurable oxytocin release in both species, which is the same hormonal pathway that mediates the bonding effects of close human relationships. Research published in Sleep Health documents that the bond between humans and their pets is, by every available physiological measure, comparable to the kinds of attachment bonds the species forms with other humans. The animal is not, in this framing, a substitute for human attachment. The animal is, more accurately, occupying the attachment system in its own right, alongside the other humans the person is also attached to.
What is distinctive about the animal-human version of the attachment, however, is the structural fact that the animal does not, in any meaningful sense, evaluate the human. The animal does not register the human’s professional standing, social status, recent performance in conversations, or the various other dimensions on which the human is, in most of her other relationships, being continuously and quietly assessed. The animal registers the human’s presence, the human’s reliability about meals, the human’s tone of voice, and the small ongoing pattern of daily contact. None of these dimensions requires the human to perform any version of herself. The dimensions are met by the human simply being there, in whatever state she actually happens to be in.
Why most adults postpone this recognition
The recognition that the relationships that work most reliably do not require performance is, on close examination, one most adults could arrive at considerably earlier than they do. The wider culture, however, has not on the available evidence developed particularly good vocabulary for this recognition, and the cultural register tends to push in the opposite direction.
The wider register treats the calibration as a feature of adult relational sophistication. The adult who is skilled at adjusting her presentation to the various people in her life is, in the wider register, the adult who is doing relationships well. The adult who declines to adjust her presentation, who insists on showing up as herself regardless of context, is, in the same register, often classified as either unsophisticated or as failing at the basic social skills the cultural environment values.
This produces, in most adults, a particular ongoing acceptance of the calibration as the structural condition of being a functional member of adult society. The calibration is real. The calibration is also, on close examination, expensive. The expense is, in the same way as in the other articles in this series, distributed across thousands of small interactions in a way that prevents it from registering as a discrete cost. The cumulative cost across decades is, however, considerable. The cumulative cost is, in some real way, the structural fatigue that adults of a certain age frequently report without quite being able to source.
The animal in the bed is the small ongoing daily counter-example to the cultural register’s assumption that all relationships require calibration. The animal does not require calibration. The animal works anyway. The animal works, on close examination, more reliably than most of the calibrated relationships in the adult’s life. The reliability is the data. The data is what the recognition is built on, when the recognition finally arrives.
What the animal is actually demonstrating
The animal is, in some real way, demonstrating something that the wider cultural register has not yet adequately credited. The animal is demonstrating that relationships do not, by structural necessity, require the calibration the cultural register treats as the price of admission. The relationships can, in some real way, work without the calibration. The animal is the proof. The proof is, in the adult’s daily experience, repeated every night.
This is not, on examination, an argument against human relationships. Human relationships are, for various good reasons, more structurally complex than animal relationships. The complexity produces, in the cases where it is well-managed, the kinds of substantive intimacy and shared meaning that the animal-human relationship cannot, by its structural limits, produce. The animal is not a substitute for this. The animal is, more modestly, the daily reminder that not every relationship has to require the work the calibrated ones require. Some relationships can be calibrated, by their structural design, to the actual person. Some relationships, by their actual design, are.
The animal is one of these. The animal in the bed is the structural example. The example is what the adult who has been calibrating in her other relationships finally registers, somewhere around her late thirties or forties, as the recognition this article is describing. The recognition is that the calibration is not, in fact, the only available configuration of adult intimacy. There are at least some relationships, including the one with the animal, that work without it. The relationships that work without it are, in their own way, more restful than the relationships that require it. The restfulness is what the adult registers, every night, as the small ongoing pleasure of having the animal there.
The acknowledgment this article wants to leave
The adult who sleeps next to her pet is not, in most cases, doing something either pathological or unserious. She is, more accurately, conducting one of her adult relationships in a configuration that does not require any of the performance the rest of her relationships, by their structural design, require. The relationship works. The relationship is, by every available measure, the most reliable one in her life, not because the animal is more substantive than the humans in her life, but because the animal is not asking her to be anything other than what she actually is on any given night.
The animal is, in some real way, the daily structural reminder of a recognition the adult could, in principle, extend to the rest of her life. The recognition is that the relationships that work most reliably are the ones that do not require her to perform. The recognition is available. The extending of it to the rest of her life is, in some real way, the slow ongoing work of adult relational development that the late thirties and forties tend to be quietly built around.
The animal is, on this reading, not the relationship. The animal is the proof of concept. The proof is what makes the wider work possible. The wider work, when it occurs, is what most of the visible relational ease of adults who have done it is, on close examination, structurally produced by. The animal in the bed is, in some real way, where the work begins. The proof has been there, sleeping next to her, all along. The recognition, when it finally arrives, is the structural acknowledgment of what the proof has been quietly demonstrating for years.
