As we enjoy the holidays and head into the new year, we need to take a moment each day to feel gratitude for the pleasures we have. But it’s not just for our mental health and happiness. Gratitude helps our physical health too. In a new study, researchers at the University of Michigan and University of California, San Francisco monitored cell phone data for over 4,800 adults for over 18 months. Each day, participants entered their exercise, sleep, stress levels, and various thought processes, such as “I have so much in life to be thankful for.” The researchers found that people who were more grateful had both lower heart rates and blood pressure. The grateful people also had increased feelings of appreciation toward other people and more frequently recognized the positive aspects each day.
