Good Relationships: The Secret to Health and Happiness
Good Relationships Come Out on Top: Harvard’s Study on Adult Development
The Harvard Study of Adult Development started in 1938 and has become the longest study of happiness. Starting as a study on adult development, the researchers realized that they had access to an unprecedented set of data. Looking at detailed physical and emotional indicators provided unique insight into a challenging factor to determine – happiness. The access to this expansive information revealed several important secrets about healthy relationships.
The research project started as a longitudinal study of Adult Development focused on psycho-social predictors of health and aging and has now been running close to 80 years. The sample group of over 700 men came from two very different groups. One from Harvard and the other from poor, inner-city Boston, covering a broad socio-economic spectrum and a variety of backgrounds. It's one of the most inclusive studies on adult life ever conducted. The study has now expanded to include spouses and the second generation of the original sample group.
The researchers recorded their quality of life and experiences, along with their physical health. Every two years they conducted surveys on topics such as marriage, career satisfaction, and social activities. And, every five years, medical testing was undertaken, including chest X-rays, blood and urine tests, MRIs and cardiograms. The results have been startling.
The current director of the study, Robert Waldinger, explains, “The surprising finding is that our relationships and how happy we are in our relationships has a powerful influence on our health." Waldinger says it wasn’t their cholesterol levels which predicted how they were going to grow old, but rather how satisfied they were in their relationships. “The people who were most satisfied in their relationships at age 50 were the healthiest at age 80," he confirms.
A Good Relationship is the Best Tonic
These results verified that those who were in good relationships lived longer and were happier, says Waldinger. The research highlighted this time and time again. Those in happier marriages experienced less physical pain, the men with support networks had less mental deterioration as they aged and people who were alone and social loners often died earlier. The findings bring to our attention how very important relationships are, and not any relationships, but healthy relationships.
Good relationships are so powerful that they protect our own bodies, even against the ravages of aging and pain. It is love that keeps us happy and healthy, it is the heart that keeps us young and strong. To this end, building strong relationships should be a lifelong pursuit and pleasure.
3 biggest lessons from good relationships:
Waldinger, who is the fourth director the project has had, sums up the three biggest life lessons they have gleaned from the study of good relationships and a good life.
- Social connections are really good for us: the study confirmed that the better socially connected people are, the longer they live. People with close relationships, not only live longer but are also healthier. Conversely, loneliness is toxic. Participants who were isolated showed their general health declining earlier, their brains deteriorating at a younger age and lived shorter lives. It is quite simple, the social connections we build buffer us as we age.
- Quality not quantity: it is not the number of relationships, but the quality of these connections which define them as good relationships. As caring relationships are protective to our health, so conflict can be even worse than divorce and has an adverse effect on our health. The people in the study who were happiest in their relationships in their 50s were healthiest in their 80s. Cultivate deep and meaningful relationships – high-quality connections are the elixir of life.
- Healthy relationships protect our brains: one of the greatest fears of the aging process is losing our faculties. The study showed that individuals in their 80s who were in securely attached relationships with someone they believed they could count on retained sharper memories. And on the contrary, the people who were alone experienced earlier cognitive decline.
Over the decades and through changing social, economic and political landscapes, healthy relationships and close connections with others, have now been scientifically proven to be the most valuable and treasured asset we can accumulate through our lifetime. Waldinger summarizes their greatest lesson simply, “good relationships keep us happier and healthier. Period."
