The Study

The Harvard Study of Adult Development, started in 1938, is the longest study on human life with a mission to uncover the secrets to good health and happiness. The original cohort of 268 student volunteers (including future president John F. Kennedy) has expanded over the years to include their offspring, varying socioeconomic classes, and women. Data collected reveals a surprising truth about us as human beings – our close relationships are what keep us happiest and healthiest throughout our lives.

Every few years, participants of the study have completed questionnaires regarding their health, marriages, careers, success and failures, and much more. They’ve shared their medical records and sat down for in-person interviews. After pouring over data and stories acquired over decades, scientists have discovered that the best predictor of health and happiness in life is having close connections with others. Our relationships are more important to our well-being than money, fame, social class, IQ, and even our genes. In fact, people who have strong, meaningful relationships in their 50s turn out to be the healthiest ones in their 80s. 

The Power of Human Connection

Why is human connection so powerful? Multiple studies reveal the positive impacts of social connections. Strong relationships lead to better mental health, lower rates of anxiety and depression, stronger immune systems, higher self-esteem, greater empathy towards others, improved ability to recover from disease, and can ultimately help us live longer lives. Think about how nice it feels to sit with others and share a piece of ourselves through stories and experiences. We laugh together, which releases endorphins in our body. Endorphins are those “feel good” hormones that give us a sense of well-being and can temporarily relieve pain. And the more we engage in social activities and reap the benefits of their impact, the more people WANT to be with us, thus creating a positive feedback loop of human connectedness.

The Effects of Loneliness

Why is loneliness so detrimental to our health? According to the Harvard study, loneliness is as harmful to us as alcoholism and smoking. In fact, we now know that feeling lonely can negatively impact our immune system, sleep patterns, blood pressure, stress hormones, and mental health. As we age over time, these impacts take a toll on our bodies and minds. And in our later years of life, social connections and support may be even harder to find with limits in mobility and a shrinking social cohort. Nurturing healthy relationships today help buffer the impact of entering our twilight years.

Becoming Connected with Others

How do we incorporate the findings of the Harvard study into our own lives for better health and happiness? How do we make new social connections and nurture the ones we already have? It’s easier than you think. Start with the people who already show up in your life. Set up date night with your partner. Go play with your kids. Reach out to a friend today and get something on the calendar – perhaps a walk along Bayshore Boulevard in the early morning or evening, a stroll through one of the various weekend markets we have in Tampa, a backyard cookout, or just a meaningful conversation on your front porch. It doesn’t need to be an expensive or time-consuming outing – it’s all about the connection.

And don’t forget to seek out opportunities in your community for expanding your social circle. Consider attending church on Sunday, finding a tennis or pickleball clinic, signing up for a cooking class, or mentoring a young person who needs guidance in life. All of these options and more are available to you. With knowledge gained from the Harvard study, we now know the key to a lifetime of happiness and good health – meaningful relationships. Let’s get started.
