Your dog is literally saving your life

Many people view dogs simply as household companions. In Bangladesh, though, it is considered more acceptable as a pet in urban households. Still, people's love for street dogs is no less. They are fed, taken care of, and provided with shelters as well. Scientific research suggests that living with a dog provides measurable benefits to human health. These benefits span physical, mental, and social areas of life. Scientists have studied these effects for decades.

Improvements in Cardiovascular Health

The most well-documented benefits of dog ownership relate to the heart. Early research by Dr Erika Friedmann established that heart attack patients with pets had higher survival rates than those without them.

A later meta-analysis showed that dog ownership is associated with a 24 per cent reduction in all-cause mortality.

This research suggests that dogs might play a causal role in reducing cardiovascular disease risk.

Experts believe these heart benefits come from several factors. Owners often have lower blood pressure and better cholesterol levels. They also tend to show healthier physical responses to daily stress.

The role of physical activity

People like to take their dogs out for a walk. Especially in Dhaka north people are seen walking with their pets in the park. It is a way of their physical exercise.

Physical movement is a major driver of these health improvements. Dog owners are more likely to achieve recommended levels of physical activity than non-owners. This is largely due to the need to walk a dog. Regular walking improves mobility and helps maintain physical function as people age.

A study of older adults found that those who owned dogs were more likely to maintain their independence in daily tasks. This added movement helps regulate body weight and improves overall fitness levels.

Mental and cognitive benefits

The impact of dogs extends to the brain and emotional well-being. Regular interaction with a dog can trigger the release of oxytocin, which is often called the bonding hormone.

This interaction helps lower cortisol levels, which is a primary stress hormone in the human body.

Research published in 2022 by Ian M. McDonough, Hillary B. Erwin, Nancy L. Sin, and Rebecca S. Allen at the University of Alabama (in collaboration with the University of British Columbia) investigated the link between pet ownership and cognitive health across the adult lifespan. Their study, titled Pet ownership is associated with greater cognitive and brain health in a cross-sectional sample across the adult lifespan and published in Frontiers in Aging Neuroscience, utilised multivariate analyses to demonstrate that pet ownership—particularly dog ownership—is associated with higher levels of cognitive performance, larger brain structures, and better processing speed, attentional orienting, and episodic memory, suggesting it may play a role in protecting against age-related cognitive decline.

Social connections and longevity

Social isolation is a significant risk factor for many health issues. Dogs act as social facilitators. They encourage interactions with neighbours and community members during walks. In the country, we see people maintaining a community as dog parents. They share a strong bond and build social connections.

This social support acts as a buffer against the stresses of everyday life. People who live alone often see the greatest health benefits from dog ownership.

Considering the evidence

While these findings are promising, researchers caution against a one-sided view. Healthier people may be simply more likely to adopt dogs in the first place.

However, the consistent link between dog ownership and positive health outcomes suggests a genuine connection. Modern medicine is increasingly looking at 'lifestyle interventions' to promote public health. Dog companionship represents a simple yet powerful way to incorporate movement and social support into daily life.
