Gratitude has been proven to be an effective way to improve our happiness and well-being, and a recent study says it might influence how long we live, too.
The study, “Gratitude and Mortality Among Older US Female Nurses,” from the Harvard T.H. Chan School of Public Health, was published in JAMA Psychiatry in July. It found that older adults who scored high on a Gratitude Questionnaire had a 9% lower risk of all-cause mortality than those in the lowest-scoring segment. Gratitude showed protection against cardiovascular disease in particular, although it appeared to be protective against every cause of mortality — even after researchers adjusted for other factors including lifestyle, sociodemographic data, health history, and social/religious involvement.
Much of the data used for the Harvard study came from the Nurses’ Health Study, which tracked over 70,000 nurses for several years. It found that those who regularly practiced gratitude reported significantly better health outcomes. Participants who engaged in gratitude exercises, such as keeping a gratitude journal or expressing thanks to others, experienced lower levels of stress and depression.
This emotional uplift not only improved their mental health but also correlated with better physical health markers, including lower blood pressure and improved immune function, researchers found.
How Gratitude Helps
Gratitude fosters a positive mindset, which is crucial for overall wellness. As people focus on what they’re thankful for, they move their attention away from negative thoughts and stressors. This shift can lead to a cascade of health benefits, including better sleep quality, which is essential for longevity. A good night’s sleep allows the body to repair itself and maintain optimal functioning, reducing the risk of chronic diseases.
Gratitude offers a social aspect as well; expressing thanks strengthens relationships, creating a supportive network that is vital for emotional resilience. The nurses’ study indicated that those who actively expressed gratitude to colleagues and loved ones reported feeling more connected and supported, which is a key factor in mental health and longevity. Strong social ties have been consistently associated with a longer life, as they provide emotional support and reduce feelings of isolation.
The benefits of gratitude extend beyond individual health. Communities that foster a culture of gratitude tend to be more cohesive and supportive. This collective positivity can lead to improved public health outcomes, as individuals are more likely to engage in healthy behaviors when they feel supported by their community.
