Pets come with powerful mental and physical health benefits for humans. Dogs especially can help reduce stress, anxiety, and depression. Dogs can also take away loneliness, encourage exercise, and improve cardiovascular health. Having a dog for your children can help them grow up to feel more secure and the kids will be more active.
I have two dogs and both of my dogs can understand my tone of voice and the words that I say to them. Dogs are able to understand the use of words that we use, and they're good at interpreting our tone in our voice, and body language. Dogs will try to understand your emotional state and try to understand how we are feeling. My dogs will both try to comfort me when I cry because they can sense me being upset. And when my mom was in the hospital and came back, they would not leave her side until she was better because they knew something was wrong.
The American Heart Association found that having dogs helped with reduced risk for heart disease and greater longevity. Studies also have found that humans who have borderline hypertension adopted dogs from a shelter and their blood pressure declined greatly within five months of having that dog. Another study also found that adults over the age of 65 make 30% less trips to the doctors than those who do not have a pet.
Dogs have proven to help improve healthy lifestyle changes for humans. Some health benefits include increasing exercise, providing companionship, reducing anxiety, adding a routine to your day, and proving a stress relief. Studies have shown that dog owners are more likely to meet their daily exercise requirements and it will keep both you and your pet healthy.
