Pets can help with depression in various ways. They provide companionship, which can reduce feelings of loneliness and isolation. The act of caring for a pet can give a sense of purpose and routine, which can be beneficial for someone experiencing depression. Additionally, interacting with pets can increase levels of oxytocin and decrease cortisol levels, leading to reduced stress and improved mood. The unconditional love and non-judgmental nature of pets can also offer comfort and emotional support to individuals struggling with depression.
