Veterinarian Pablo Antonio Olmedo, known on social media as @pablo_vet83, says that sleeping with a dog or cat can reduce stress and anxiety, promote sleep, and strengthen emotional bonds. He added that their rhythmic breathing, body heat, and presence create a calming effect similar to that of a hug.
Sleeping beside a pet can also boost levels of oxytocin, the "feel-good" hormone, while lowering cortisol, which is linked to stress. According to the vet, this can lift mood and make it easier to fall asleep.
Benefits of sharing your bed with a pet
The National Sleep Foundation and the American Psychiatric Association (APA) point out that the presence of an animal can alleviate anxiety, reduce loneliness, and reinforce a sense of security, especially for those who live alone. Studies at Washington State University have found that stroking a dog or cat for just 10 minutes can significantly reduce cortisol levels.
"Sharing such an intimate moment strengthens trust and emotional connection," veterinarian Pablo explains. Some pet owners have also reported better moods upon waking, along with a reduction in symptoms of depression.
Potential downsides and health risks
However, the American Academy of Sleep Medicine warns that one-third of people who share their bed with pets experience frequent disruptions to their sleep. Pets have different sleep patterns, tend to shift position, make noise, or get up during the early hours, all of which can negatively affect the quality of human sleep.
Pets can also carry parasites, bacteria, or allergens, particularly if they have not been vaccinated or regularly treated for worms. For those with allergies or asthma, having fur in the bedroom can aggravate symptoms. The Mayo Clinic notes that the risk of infection remains low when pets receive proper veterinary care, though it recommends maintaining good hygiene for both the animal and bedding.
Practical recommendations for pet owners
Regular grooming of your pet, frequent washing of bed linen, and routine visits to the vet are all crucial measures to reduce potential risks. Allowing your pet to share your bed could also encourage emotional reliance, resulting in heightened separation anxiety whenever the owner is away. As such, some specialists recommend permitting animals to sleep in their own beds within the bedroom.
Ultimately, the decision rests with each individual pet owner, and experts stress the importance of prioritising what is safest for both you and your pet.
