For many pet owners, sharing a bed with a furry companion is a nightly ritual – but is it beneficial? A growing body of research is beginning to unpack the complexities of co-sleeping with animals, moving beyond anecdotal observations to examine its effects on sleep quality, emotional well-being, and even our broader capacity for empathy. While a definitive “good” or “bad” answer remains elusive,understanding the psychological factors at play can offer insight into this increasingly common practice and help individuals make informed choices for a more restful – and connected – night’s sleep.
Do you ever wake up pressed against the edge of the mattress while your dog or cat sprawls comfortably in the center of the bed? For many households, it’s a common scene. While often dismissed as a quirky habit, psychology and recent studies are beginning to reveal that sharing your bed with a pet is more complex than just dealing with pet hair on the sheets. Understanding the reasons behind this behavior can offer insights into human-animal bonds and their impact on well-being.
Sleeping with a pet isn’t automatically good or bad. It does affect sleep, but also reflects how we relate to animals, our own wellness, and even how we view the world around us.
A Surprisingly Common Practice

Data confirms that sharing a bed with a pet is far from unusual. A classic study by the Mayo Clinic analyzed 40 adults who slept with their dogs in the bedroom. Researchers found that participants generally maintained good sleep efficiency, though sleep quality dipped slightly when the animal moved from the floor to the bed.
More recent research, involving 1,591 adults in the United States, expanded on these findings. Individuals who slept in the same room as their pets reported, on average, lower subjective sleep quality and more symptoms of insomnia compared to those who didn’t. However, the study didn’t find significant differences in overall sleep efficiency or other measures of sleep health. This suggests that while objective sleep metrics may not be dramatically affected, people often *feel* less rested when sharing their bed.
Many people report feeling more “accompanied” while sleeping with their pets, even if their sleep is objectively lighter. This balance between emotional comfort and physical comfort offers clues about who chooses to share their bed with an animal.
Attachment, Security, and the Need for Connection
The psychology of the human-animal bond has long explored why some people consider their dogs or cats to be family members. Research shows that pets can function as attachment figures, providing a sense of security and a safe base during times of stress. This can be particularly important for individuals seeking emotional support.
A study of over 200 dog and cat owners found that those who felt their pets provided emotional support also reported greater psychological well-being, even when considering support from family or partners. The findings highlight the significant role pets can play in mental health.
People who allow their dogs or cats into their beds often seek feelings of safety, companionship, and immediate affection. They are often willing to be vulnerable, falling asleep with a relaxed expression and their animal close by. This willingness to prioritize emotional connection is a significant aspect of the practice.
Empathy and Our Broader Outlook
Research also suggests a link between emotional connection with pets and broader empathy. A 2024 study published in Frontiers in Psychology analyzed 343 people and found that a stronger emotional bond with a pet was associated with increased empathy towards animals and, consequently, more prosocial attitudes towards other people.
In simpler terms, the more you care about the well-being of your dog or cat, the more likely you are to be concerned when others are suffering. Daily interactions with pets can provide practice in care, patience, and attention to nonverbal cues.
Environmental research goes further, suggesting that this empathy can extend to nature. Studies with children show that those who feel more “empathy with nature” are more likely to develop attitudes favorable to protecting the environment and adopting eco-friendly behaviors. While no study directly links sleeping with a pet to environmental activism, this sensitivity to other living beings aligns with profiles of people who are more concerned about the environment, animal welfare, and everyday decisions like purchasing and transportation.
Routine, Responsibility, and Adaptability
Sharing a bed with a pet often means sharing a schedule. Dogs and cats are creatures of habit, and often dictate wake-up times or when lights are turned off. This routine, when well-managed, can help maintain regular schedules, which is known to benefit sleep and mood.
However, it also requires flexibility. Sleeping with an animal means accommodating paws on your back, occasional snoring, or unexpected jumps in the middle of the night. Those who maintain this habit are often adaptable, willing to negotiate boundaries, and accept some discomfort in exchange for connection.
Prioritizing Sleep Health, Cherishing Connection
The less romantic side of the equation is that the data isn’t perfect. The most recent study on co-sleeping with pets indicates that those who sleep in the same room as their animals report, on average, lower perceived sleep quality and more symptoms of insomnia, particularly with dogs, although objective sleep efficiency doesn’t change much.
What does this mean in practice? Each household needs to find its own balance. If you frequently wake up tired, experience chronic insomnia, sleep apnea, or allergies, it may be best for your dog or cat to sleep in the same room but in their own bed. If you sleep well and the sense of companionship is valuable, there’s no universal rule requiring you to change.
The key is to understand what you’re gaining and what you’re potentially losing – proximity, emotional security, and a bond with another living being versus potential disruptions and slightly fragmented sleep. Fortunately, this choice can be revisited as often as needed.
In conclusion, sleeping with your pet often reflects someone who values connection over perfection, is sensitive to animal welfare, and is willing to adjust their comfort for a close bond. These are quiet strengths that don’t show up on a medical test, but are noticeable in everyday life.
The most recent scientific study on how sleeping with pets relates to human sleep quality was published in the journal Scientific Reports.
