Pets can reduce stress levels in a variety of ways. One common way is through the release of oxytocin, a hormone that promotes bonding and reduces stress. Additionally, the act of petting an animal can lower cortisol levels, a stress hormone. Pets can also provide companionship and a sense of purpose, which can help reduce feelings of loneliness and anxiety. The playful and carefree nature of pets can also help distract their owners from stressful thoughts and situations, leading to an overall sense of calm and well-being.
