Pets can help with depression in several ways. They provide companionship, emotional support, and unconditional love, which can help reduce feelings of loneliness and improve mood. Taking care of a pet can also create a sense of routine and purpose, leading to increased motivation and self-esteem. Additionally, interacting with pets can release feel-good hormones such as oxytocin and dopamine, which can help reduce stress and anxiety. Overall, the presence of a pet can bring comfort and joy to those struggling with depression.
