Why Women Sleep Better with Dogs than Humans or Cats, According to New Research

Sleep is essential for good health, but finding the best way to get restful sleep is not always easy. While some rely on chamomile tea or bedtime routines to improve sleep quality, new research suggests a surprising addition to the list of sleep aids: dogs. According to a study by Canisius College in New York State, women report sleeping better next to their dogs than with human or feline companions. Here, we’ll explore the reasons behind these findings and the unique benefits dogs may provide as sleep partners.

The Study: Why Dogs Are Better Sleep Partners for Women

The study, led by Christy Hoffman, Ph.D., an animal behaviorist and the study’s lead researcher, surveyed nearly 1,000 women across the United States. Of these, 55% reported sleeping with at least one dog, 31% with a cat, and 57% shared their bed with a human partner. The results revealed that women often found their dogs to be the best bed partners, citing improvements in sleep quality and security as primary benefits.

“We found that women commonly rate dogs as better bed partners than cats and human partners and report that their dogs enhance their sleep quality,” Hoffman explained.

This finding prompts us to examine the science behind it: what makes dogs such great sleep companions?

Why Dogs May Improve Sleep Quality

Aligned Sleep Patterns

One reason dogs may improve sleep quality is their natural alignment with human sleep schedules. Unlike cats, who are known for their nocturnal tendencies, dogs tend to sleep at the same time as their owners. Hoffman noted that dogs have major sleep cycles that more closely resemble human sleep patterns compared to cats. This alignment means fewer disturbances, allowing both the dog and owner to enjoy uninterrupted sleep.

“Dogs’ major sleep periods tend to coincide more closely with humans’ than do cats’, so it’s not surprising that dogs may enhance sleep quality,” said Hoffman.

Adaptability to Human Schedules

Another factor in why dogs make better sleep partners is their adaptability to human routines. Unlike human partners who may have different work schedules or preferences for when they go to bed and wake up, dogs tend to adapt to their owner’s lifestyle. They adjust to the times their owner is active and at rest, minimizing sleep disruptions.

“Human partners often have different schedules, leading to disruptions in sleep,” Hoffman explained. “Dogs, on the other hand, readily adjust to their owner’s sleep schedule, which can lead to more consistent and peaceful rest.”

Daily Routines for a Better Sleep Cycle

Dogs are creatures of habit and require regular routines like feeding times, bathroom breaks, and morning walks. These routines help dog owners maintain a structured lifestyle that supports good sleep hygiene. Knowing that they need to walk their dog in the morning encourages owners to go to bed at a reasonable time and wake up early, which may contribute to overall better sleep quality.

Dogs Offer Security and Comfort

A Sense of Safety and Protection

One of the most significant benefits reported by women who sleep with dogs is a heightened sense of security. The presence of a dog can provide comfort and peace of mind, especially for those who live alone or may feel vulnerable at night. A dog’s natural protective instincts, combined with their ability to alert owners to unusual sounds or potential threats, make them ideal for providing a sense of safety.

“Some dog owners take comfort in knowing their dog will alert them if there’s an intruder or emergency,” Hoffman said. “A dog’s bark alone can deter potential intruders, which can make owners feel safer.”

Cats and human partners typically don’t provide this same level of reassurance. While a cat may offer companionship, they are unlikely to respond to unusual sounds or movements in the same protective way as a dog.

Stillness and Reduced Movement During Sleep

Many dog owners appreciate their pet’s tendency to stay still throughout the night. Unlike cats, who are known to wander around and jump on and off the bed, dogs often remain in one place, creating a stable and quiet sleep environment. This stillness minimizes sleep disruptions and helps women feel relaxed and undisturbed.

“Cats are more likely to create disturbances by moving around, while dogs tend to stay settled, creating a stable and restful atmosphere,” Hoffman noted.

How Sleeping with a Dog Compares to a Human Partner

While many women prefer to sleep with their pets, especially dogs, over human partners, it’s important to note that the benefits of sleeping with a dog can vary. For some, human partners might provide warmth and comfort, but they often come with their own sleep habits and schedules that don’t always align with their partner’s needs. Dogs, on the other hand, are less likely to disrupt sleep since they quickly adapt to their owner’s sleep patterns and routines.

“With a human partner, different schedules and sleep habits can cause frequent disruptions, making it harder to get a good night’s rest,” Hoffman explained. “Dogs simply follow their owner’s routine, providing a consistent and peaceful sleep experience.”

Additional Benefits of Sleeping with a Dog

Improved Mental Health and Reduced Anxiety

Sleeping with a dog offers more than physical comfort; it can also have positive effects on mental health. The presence of a dog can reduce anxiety, promote relaxation, and increase the release of oxytocin, a hormone associated with feelings of love and connection. These benefits make dog owners feel more secure and less stressed, ultimately improving their quality of sleep.

Enhanced Bonding and Companionship

For many dog owners, sharing a bed with their pet fosters a stronger bond. Dogs are highly social animals, and their presence can provide a comforting sense of companionship. This close proximity at night strengthens the bond between owner and pet, creating a mutual sense of trust and affection that enhances emotional well-being.

Are There Any Downsides to Sleeping with a Dog?

While the benefits of sleeping with a dog are well-documented, there are some potential downsides to consider. Dogs may occasionally snore, move around in their sleep, or become too warm, which could disrupt sleep for some individuals. Additionally, people with allergies may find it challenging to sleep with a dog nearby, as pet dander could trigger allergic reactions.

“Some dogs snore or shift positions, which may cause minor disturbances,” Hoffman noted. “However, these issues are usually outweighed by the benefits for those who feel more comfortable and secure with their dog by their side.”

Future Research on Pets and Sleep Quality

Hoffman’s study primarily relies on self-reported data, meaning the findings are based on how participants perceive their sleep quality rather than objective measurements. Future research could use sleep-tracking devices, similar to Fitbit, to collect objective data on sleep patterns and quality. Such studies would provide more detailed insights into the effects of sleeping with a pet, including the potential benefits and drawbacks for different individuals.

Hoffman believes these studies could provide valuable information, particularly as more American households incorporate pets into their daily lives. Understanding the conditions under which pets enhance sleep quality—and when they may disrupt it—would offer guidance to pet owners looking to optimize their sleep experience.

“By studying sleep patterns with pets more objectively, we can better understand how co-sleeping with animals may impact sleep quality and how to maximize the benefits,” Hoffman concluded.

Conclusion: The Canine Advantage for Better Sleep

In a world where quality sleep is often elusive, the companionship of a loyal dog could be a surprisingly effective sleep aid. Hoffman’s study suggests that dogs may offer unique benefits as sleep partners, from synchronized sleep patterns to a strong sense of security. These factors contribute to a more restful night, making dogs ideal companions for those seeking peace and comfort while they sleep.

Although more research is needed to fully understand the impact of pets on sleep, the evidence so far points to a positive effect for dog owners. For women especially, a dog may provide not only an effective sleep solution but also a comforting, reliable presence that enhances their well-being. So, the next time you consider who—or what—might help you get a better night’s sleep, a four-legged friend might just be the perfect answer.
