New research shows that our beloved pets may be hurting our sleep.
Though pets can have many positive effects on health, pet ownership was linked with poorer sleep, according to a recent study published in the journal Human-Animal Interactions.
As NBC News reports, the researchers looked at data from the National Health and Nutrition Examination Survey, which asks questions on a variety of health topics. They adjusted for factors that could affect sleep, including race and income, as well as age, gender and BMI, and focused on whether a person had a sleep disorder and whether a person had a cat or a dog.
Sleep quality was measured by looking at reported bouts of snoring or snorting at night; being diagnosed with a sleep disorder; having trouble sleeping or falling asleep; waking up during the night; waking up too early; feeling unrested; not getting enough sleep; needing medication to sleep; or having leg jerks or cramps. Taking longer than 15 minutes to fall asleep and regularly getting less than six hours of sleep were also indicators of poor sleep.
The findings showed that having a dog was associated with a greater chance of having a sleep disorder and overall having trouble sleeping, while having a cat was associated with having a higher chance of leg jerks in the night.
The study was observational, meaning the researchers could not say for certain the pets caused poor sleep, but the results were consistent with previous studies that found that pet ownership negatively affected sleep quality.
Lead study author Lauren Wisnieski, an assistant professor of public health and research at Lincoln Memorial University in Tennessee, noted that the study didn’t look at where people’s pets slept. For example, is a dog taking up all the space on the bed? Is a cat curling up right next to the pet owner’s head?
That would be a good direction for future studies, she said, “to ask owners more about where their pets sleep and how those pets are disrupting their sleep.”
How to get Better Sleep with your Pet
Lieve van Egmond, a sleep researcher at the Uppsala Sleep Science Laboratory in Sweden, was not involved with the new study, but did lead a separate study that also used self-reported data to examine how pets may affect sleep, in an attempt to deal with the problems she was having with her own cat keeping her up at night.
In that study, published in 2021, van Egmond and her team found that having a cat was associated with a shorter night’s sleep, but having a dog was not linked to changes in sleep. Still, she noted that more research would need to be done to establish whether the findings were a coincidence, or if pets were truly causing sleep issues.
She said the association found in the new study likely has more to do with owning a pet — and the many different factors tied to that unique cat or dog — rather than where those pets sleep. “The age of the pet has a big influence on whether or not they keep you up at night,” van Egmond said. “If you have multiple pets, they can egg each other on.”
With dogs, she said, it depends a lot on the breed and the activity level it needs. Making sure a pet gets plenty of physical activity and mental stimulation during the day and working with its natural instincts can help animals — and their owners — get better rest. Unlike dogs, cats tend to have bursts of energy at night, van Egmond said.
She consulted a cat behavioral specialist and learned that if playing with a cat for bed activates the cat’s hunting instinct. By being fed after that, the cat would feel that he had successfully hunted his food and was rewarded with a nice meal in return. His natural instinct after that was to groom himself and go to sleep, just as you’re getting ready to hit the hay yourself.
The new study “indicates that pets can influence your sleep, but we have to really take into account that pets are much more than a facilitator or inhibitor of sleep. They are part of the family,” she said. Still, people can use this information to evaluate why they may not be getting enough rest, she said.
“If they have pets and they have poor sleep, they should look at where this is coming from,” van Egmond said. If it is the pet, “see where the bottleneck is and how you can make it so the cat or dog will not interrupt you when you are sleeping.”
