Sleeping with your pet is an increasingly widespread habit, to the point of becoming almost natural for many owners. Dogs and cats are no longer just everyday companions: they occupy a central emotional place, often comparable to that of a family member. And this closeness sometimes extends into the bedroom. Thus, according to a survey conducted by the American Academy of Sleep Medicine, nearly 46% of those questioned sleep with their animal.
But behind this emotional gesture hides a more nuanced reality, where emotional benefits coexist with sometimes less favorable effects on sleep.
Real emotional comfort
It is an established fact. Sleeping with your pet above all meets a need for security and proximity. Sleep is a time of vulnerability, and the presence of a companion by your side can alleviate this feeling. Many owners describe a feeling of calm, warmth, and reassurance when falling asleep with their pet.
Research into human-animal interactions confirms these feelings. Having a pet can help reduce stress, reduce anxiety, and improve overall well-being. As researcher Kaitlyn Medlin explains in a previous article, animals play an important social support role: they help fight loneliness and contribute to better emotional regulation. Waking up with your pet can thus reinforce the feeling of having had a good night’s sleep, even if this impression remains subjective.
A sometimes misleading perception of sleep
Because while the feeling is often positive, scientific measurements provide a more contrasting perspective. When sleep is analyzed using objective tools, such as sensors or smartwatches, the results show that sleeping with an animal can lead to more fragmented sleep.
In other words, it is entirely possible to have the impression of sleeping well while the body is experiencing more micro-awakenings. These disturbances often go unnoticed, but they can alter the overall quality of rest.
A study published in 2023 in Human-Animal Interactions already highlighted this ambivalence. She points out that animals can improve emotional well-being through the support they provide… while disrupting their owners’ sleep through their movements or nocturnal reactions.
Nights with a cat or a dog are different
The impact of co-sleeping also varies depending on the animal. Dogs, for example, tend to be more sensitive to external stimuli like noises or movement. This alertness may cause them to move or wake up more often. Even barking. Which, unless they sleep soundly, directly influences their master’s rest.
Cats, on the other hand, show more variable results. Some remain calm all night, while others adopt a more active nocturnal rhythm (times of play, or hunting, etc.). These differences show that bed sharing depends as much on the behavior of the animal as on the habits of the person.
A long-term health issue
Even if these disruptions may seem innocuous to you, they are not without consequences. Poor quality sleep, over time, can affect general balance. Fatigue, irritability, difficulty concentrating or even reduced stress tolerance can appear gradually.
Thus, the emotional comfort provided by the animal must be weighed against the physiological needs of the body. Because truly restorative sleep remains essential for mental and physical health.
A compromise between heart and reason
Experts agree that there is no universal answer. Veterinarian Sandra Mitchell reminds us that sleeping with your pet is neither a good nor a bad thing in itself. It all depends on the context, the temperament of the animal, its education, its state of health and the habits of the owner. But this decision must be considered from the first months of cohabitation, because it has a lasting influence on lifestyle habits.
Ultimately, sleeping with your pet is about a subtle balance. On the one hand, there is emotional comfort, the feeling of security and the strengthened bond with the animal. On the other hand, there is the physiological reality of sleep, sometimes more fragile than we think.
Rather than deciding between “good” or “bad”, it seems more relevant to question one’s priorities. Are we primarily looking for emotional comfort, or perfectly restorative sleep? Understanding this compromise allows you to make an informed choice, adapted to your lifestyle and that of your companion. And without feeling guilty: there are many other ways to show your affection to your four-legged friends.
