First, the interaction of pets with humans can increase our hormone levels. When we interact with our pets, our brains release hormones like dopamine and oxytocin. Dopamine is a hormone associated with feelings of pleasure and reward, while oxytocin is a hormone associated with closeness and social behavior. The release of these hormones can help us feel happy, relaxed and satisfied.

Second, pets can help us reduce stress and anxiety. Studies have shown that interacting with pets can lower our blood pressure and heart rate and reduce the production of stress hormones. In the face of stress and anxiety, playing with, petting or simply spending time with our pets can help us relax and relieve feelings of stress and anxiety.

Third, pets can improve our social skills and interpersonal relationships. Owning a pet can become a topic for us to communicate with others and help us build new social relationships. Pets can also be a bond between us and others, bringing more communication and interaction. In addition, pets can provide companionship and support to help us overcome loneliness and social barriers.

Fourth, pets can promote our physical health. Outdoor activities with pets, such as walking the dog or taking the cat outside for a walk, can increase our exercise. Studies have shown that exercising with pets can help us lose weight, improve cardiovascular health, and boost immune system function. In addition, interacting with pets can also increase our activity level, improve blood circulation and burn energy.

Finally, pets can provide emotional support and comfort. Pets can be not only our companions and friends, but also our emotional supporters. Whether in times of loneliness, sadness or anxiety, pets can always provide us with unconditional love and care. Their presence can bring us comfort and security and help us through difficult times.

To sum up, the happiness pets bring us is not accidental, but based on scientific principles. Interacting with pets can increase our hormone levels, reduce stress and anxiety, improve social skills and relationships, promote physical health, and provide emotional support and comfort. So, if you don't already have a pet, considering these scientific principles may make you more determined to own a pet and share the joy and love with them.
