We have known for years that living with a dog is good for our mental and physical health. And also it helps to prevent allergy forms in children. Now we know a little bit more: researchers are examining dogs' germs and comparing them to those of humans, discovering that bacteria that live inside and on animals are the key to explaining the best way to friend protects human health.
Microbes and allergies at home (and not only). The best strategies to try to defend themselves

The variety of bacteria
In the last 5 years, many studies have focused on the microbiome (the billions of living healthy bacteria in our intestine). No research has yet given the last word on the issue, but scientists believe that it is likely that dogs will bring back diverse bacteria that help children strengthen the immune system. Studies show that the diversity of types of microbes is important and that the environment in which a person lives can have an impact on this diversity. The microbiome influenced by internal and external factors. The fact that Americans spend more than 90% of their time indoors might be one of the reasons why more people have suffered from asthma and allergies: "Hygiene", without exposure to a variety of bacteria, the immune system lose strokes to learn which bacteria are dangerous and which are harmless. And the reason why at least a dozen studies have shown that children born to families with significant exposure to farm animals had fewer cases of asthma.

But not for the elderly
Dogs, with their propensity to attack the nose on the ground, plants and other dogs, bring at home a variety of external bacteria and can help us better train the immune system. A Canadian study showed that children living with a dog or cat had a more diverse group of microbes in their gut. Dogs can also alter the composition of dust bacteria in the home, which leads to less allergies. A recent study conducted by the American Institute of Allergy and Infectious Diseases found that dust was significantly different in homes where a dog lived a year, compared to those who did not have a baby. animals. Another study on asthma found that 3 – month – old children who lived in homes with a number of animals and other allergens were less likely to have children. ;asthma. The help of immune system dogs is definitely stronger in young people. The University of Arizona at Kelly recently completed a study on the elderly, aged 50 to 80, and on this "ability" of dogs. The work showed that after 3 months there was no change in the microbes of the subjects
