At night, cuddle up and chill out with a furry or feathered friend. “Pets offer a tangible connection to inner happiness and help renew your energy,” says Kristen Levine, author of Pampered Pets on a Budget. Studies show that being around a pet releases feel-good endorphins and elevates calming serotonin and dopamine. Plus, pet owners have less risk for depression and heart disease. Even a goldfish gliding through water can be calming. And pets remind us to live in the moment—perhaps the most soothing message of all.
