Having pets can help boost immunity because they can help reduce stress, increase mood, increase exercise, improve indoor air quality, and thus improve the immune system. In addition, they can provide social support and soothing, which can also promote the health of the immune system. Existing research shows that people living in rural areas have significantly lower asthma incidence than those in urban areas, because the environment in urban areas is too clean to be exposed to and adapt to more allergens.
If you have a puppy or kitten at home, you can help children adapt to allergens in advance and reduce the incidence of respiratory diseases.
Moreover, keeping pets can relieve people's sense of loneliness and bring a little comfort to the body and mind. If you feel relaxed, you will naturally have a strong resistance.
