Pets May Boost Immunity

Studies suggest that living with pets can be good for our immune systems. The Amish, who live in close contact with animals, have lower rates of allergies compared to the Hutterites, who have adopted industrialized agricultural technologies. Research indicates that exposure to microbes from animals, like those found on farms, can reduce the risk of asthma and allergies. The 'mini-farm effect' suggests that the number of pets in a home during early years can decrease allergy risk. While the idea of pets directly colonizing our microbiomes is debated, experts believe pets play a vital role in stimulating our immune systems. They may act as a vehicle to transfer human microbes and stimulate the immune system to manage bacterial populations. Studies show that humans who live with pets have more similar gut microbiomes. Researchers are exploring how reintroducing animals into our lives can benefit our health, including analyzing the impact of pet ownership on older adults and children. Regular exposure to diverse microbes through pets and outdoor activities can improve the immune system's ability to manage microbes.
