Good Health makes your Life Happy

Good health is the key for happiness

Good health make us happy Studies show that a person’s health is one of the strongest predictors of happiness. But the connection between health and happiness is complex. Research shows little correlation between a person’s objective health — as defined by medical assessment — and happiness.

The biology of emotion—and what it may teach us about helping people to live longer

Could a sunny outlook mean fewer colds and less heart disease?

Do hope and curiosity somehow protect against hypertension, diabetes, and respiratory tract infections?

Do happier people live longer—and, if so, why?

These are the kinds of questions that researchers are asking as they explore a new—and sometimes controversial—avenue of public health: documenting and understanding the link between positive emotions and good health.

A vast scientific literature has detailed how negative emotions harm the body. Serious, sustained stress or fear can alter biological systems in a way that, over time, adds up to “wear and tear” and, eventually, illnesses such as heart disease, stroke, and diabetes. Chronic anger and anxiety can disrupt cardiac function by changing the heart’s electrical stability, hastening atherosclerosis, and increasing systemic inflammation.

Jack P. Shonkoff, Julius B. Richmond FAMRI Professor of Child Health and Development at HSPH and at the Harvard Graduate School of Education, and Professor of Pediatrics at Harvard Medical School, explains that early childhood “toxic stress”—the sustained activation of the body’s stress response system resulting from such early life experiences as chronic neglect, exposure to violence, or living alone with a parent suffering severe mental illness—has harmful effects on the brain and other organ systems. Among these effects is a hair-trigger physiological response to stress, which can lead to a faster heart rate, higher blood pressure, and a jump in stress hormones.

Focusing on the positive

“But negative emotions are only one-half of the equation,” says Laura Kubzansky, HSPH associate professor of society, human development, and health. “It looks like there is a benefit of positive mental health that goes beyond the fact that you’re not depressed. What that is is still a mystery. But when we understand the set of processes involved, we will have much more insight into how good health works.”

Kubzansky is at the forefront of such research. In a 2007 study that followed more than 6,000 men and women aged 25 to 74 for 20 years, for example, she found that emotional vitality—a sense of enthusiasm, of hopefulness, of engagement in life, and the ability to face life’s stresses with emotional balance—appears to reduce the risk of coronary heart disease. The protective effect was distinct and measurable, even when taking into account such wholesome behaviors as not smoking and regular exercise.

Keys to a happier, healthier life

Research suggests that certain personal attributes—whether inborn or shaped by positive life circumstances—help some people avoid or healthfully manage diseases such as heart attacks, strokes, diabetes, and depression. These include:

  • Emotional vitality: a sense of enthusiasm, hopefulness, engagement
  • Optimism: the perspective that good things will happen, and that one’s actions account for the good things that occur in life
  • Supportive networks of family and friends
  • Being good at “self-regulation,” i.e. bouncing back from stressful challenges and knowing that things will eventually look up again; choosing healthy behaviors such as physical activity and eating well; and avoiding risky behaviors such as unsafe sex, drinking alcohol to excess, and regular overeating

Among dozens of published papers, Kubzansky has shown that children who are able to stay focused on a task and have a more positive outlook at age 7 report better general health and fewer illnesses 30 years later. She has found that optimism cuts the risk of coronary heart disease by half.

Kubzansky’s methods illustrate the creativity needed to do research at the novel intersection of experimental psychology and public health. In the emotional vitality study, for example, she used information that had originally been collected in the massive National Health and Nutrition Examination Survey, or NHANES, an ongoing program that assesses the health and nutritional status of adults and children in the United States. Starting with the NHANES measure known as the “General Well-Being Schedule,” Kubzansky crafted an adaptation that instead reflected emotional vitality, and then scientifically validated her new measure. Her research has also drawn on preexisting data from the Veterans Administration Normative Aging Study, the National Collaborative Perinatal Project, and other decades-long prospective studies.

A happiness policy?

Good health makes you happy

If scientists proved unequivocally that positive moods improve health, would policymakers act? Some observe that, in the U.S., we define “happiness” in economic terms—the pursuit of material goods. They contend that even an avalanche of research showing that emotional well-being protected health would have no traction in the policy world. Many Americans believe, after all, that people are responsible for their own lives beacause your good health will make you happy.

But others see direct policy implications. “In public health, it’s important to understand how we can translate guidelines into behavior,” notes Eric Rimm, HSPH associate professor in the Departments of Epidemiology and Nutrition and director of the program in cardiovascular epidemiology. “Seventy to 80 percent of heart attacks in this country occur not because of genetics nor through some mysterious causative factors. It’s through lifestyle choices people make: diet, smoking, exercise. Why are people choosing to do these things? Does mood come into play?”

The toll of toxic stress goes far beyond poorer health for individuals—population-wide, the cost of chronic diseases related to these conditions is enormous. “Imagine if we could enact a policy that would reduce heart disease by just 1 percent,” suggests Shonkoff. “How many billions of dollars and how many lives would that save? Now what if we could also reduce diabetes—which is growing in epidemic proportions—and even stroke?” The point, Shonkoff says, is that society pays a considerable cost for treating chronic diseases in adulthood, and reducing toxic stress early in life may actually get out in front of these diseases to prevent them.
