However, simply adding just 20 minutes of daily physical activity may reduce the risk of disease and improve mental health, according to research published in “JAMA Internal Medicine.” Research continues to show physical activity, like walking, reduces stress, boosts mood and promotes overall well-being. If you can’t find 20 minutes for a walk outside, even short bursts of movement can help. Plus, taking your furry friend for a stroll can support heart health, lower stress and boost overall happiness. a study published in the “Journal of Physical Activity and Health” shows dog owners are 34% more likely to reach their fitness goals and get the recommended amount of physical activity than those who don’t have a dog.
