Having a family pet is a favorable idea considered by many. While parents of young children are worried about bacteria and germs being an issue, there are also other factors to consider. Many studies, like ‘The Power of Pets’ published in the News in Health, have shown how pets play a very important role in a child’s development. They explain how pets have been observed to lower cortisol levels as well as lower blood pressure. They also pointed out that studies have found pets to lower the feeling of loneliness, increase social support as well, and boost your mood. A new study shows a favorable result for families who wish to have pets, especially dogs, as they not only passively help your kid’s health, but they can also have an active effect on them. New research suggests that having a family dog might lower a baby's chances of getting eczema later in life. This study, published on June 4th in the journal Allergy, indicates that being around dogs could actually change how a child's genes react to eczema, by calming down skin inflammation. How Does Eczema Affect Kids? Researchers explained that while we know genes play a role in eczema risk and that dogs might be protective, this is the first study to show how this happens at a very basic level. Eczema happens when something irritates the skin, causing it to become dry, itchy, and inflamed. We know some people are born more likely to get eczema, but exactly how their genes and their surroundings work together to either increase or decrease this risk hasn't been clear. How Was The Research Conducted? The researchers conducted a comprehensive analysis of data from 16 previously conducted studies. Their goal was to identify interactions between 24 specific genetic variants already known to be linked to eczema and a list of 18 environmental factors that could potentially influence a baby's susceptibility to the condition later in life. which included over 25,000 people, narrowed down the environmental factors to seven key ones: antibiotic use, owning a cat, owning a dog, breastfeeding, having an older sibling, smoking, and hygiene. Dogs, Genes, and Inflammation The team then applied these findings to data from another 254,000 people to see which genes and environmental factors had the biggest impact on eczema risk. This second look found that a baby's exposure to dogs affects the interleukin-7 gene. This gene is involved in making a type of immune protein that helps control inflammation. Lab tests showed that being around dogs interacts with a gene variation that might otherwise cause eczema, essentially reducing skin inflammation by changing how interleukin-7 proteins work in human skin cells. The experts explained that their research aims to answer common questions parents ask, like "Why does my child have eczema?" and "What can I do to protect my baby?" While these findings are exciting, the researchers also stressed that more studies are needed to confirm what they found in the lab and to better understand exactly how dogs might affect human genes in this way. Researchers believes these findings give us a chance to tackle the rise of allergic diseases and protect future generations.
