It turns out our furry best friend might be our sleep enemy. Lots of pet owners let their animals sleep on the bed with them, which usually disrupts sleep. But many would say it's worth it.

And researchers don't necessarily disagree.

Melissa Milanak, a professor at the Medical University of South Carolina specializing in sleep health, said most people at her clinic say their pets disturb them often at night. You can't say that hands down, it's bad for every single person, but there is a lot out there saying it negatively impacts your sleep, she said.

Generally speaking, having a pet is good for many people's health. Pets have been shown to lower their humans' stress levels, get them to exercise and more. Many pet owners also say they feel an immeasurable amount of comfort by having their pets close as they sleep.

But dogs' and cats' natural sleep cycles aren't the same as those of humans.

Dogs tend to be light sleepers and wake up multiple times at night. Some display instinctual behavior like scratching at bedding, which can prevent deeper phases of sleep, even if it doesn't wake you up. As many cat owners know, the zoomies often happen before they are ready to get out of bed. Cats evolved to hunt in low light, meaning they are particularly active at dusk and dawn.

Milanak also said allergens such as pet dander and microbes brought into the house can affect owners' breathing, preventing them from getting enough deep sleep.

Brian Chin, a professor of social and health psychology at Trinity College in Connecticut, said his research has found that sleeping with pets was associated with poor sleep, particularly those dimensions of sleep quality and insomnia symptoms. That's even accounting for the fact that pet owners may be less inclined to report problems in a survey because they don't believe their beloved pets cause problems.

Despite many problems, many pet owners feel that the bonding and emotional benefits outweigh the minor sleep disruption.
