Pets can have a positive impact on mental illness in several ways. The companionship and unconditional love that pets provide can help reduce feelings of loneliness and isolation. Caring for a pet can also give a sense of purpose and responsibility, which can improve mood and self-esteem. Additionally, the routine of taking care of a pet, such as feeding, grooming, and exercising them, can help establish structure and a sense of normalcy in daily life. Studies have shown that interacting with pets can help reduce stress, anxiety, and depression, and even lower blood pressure and improve overall well-being.
