If your glass is half full, you will live longer, healthier

Seeing the brighter side of life linked with increase in physical activity, less use of tobacco, lower risk of dying

RESEARCHERS ARE finding that thoughts like these, the hallmarks of people sometimes called “cockeyed optimists,” can do far more than raise one’s spirits. They may improve health and extend life. There is no longer any doubt that what happens in the brain influences what happens in the body. When facing a health crisis, actively cultivating positive emotions can boost the immune system and counter depression. Studies have shown an indisputable link between having a positive outlook and health benefits like lower blood pressure, less heart disease, better weight control and healthier blood sugar levels.

Even when faced with an incurable illness, positive feelings and thoughts can greatly improve one’s quality of life. Dr Wendy Schlessel Harpham, a Dallas-based author of several books for people facing cancer, including “Happiness in a Storm,” was a practicing internist when she learned she had nonhodgkin’s lymphoma, a cancer of the immune system, 27 years ago. During the next 15 years of treatments for eight relapses of her cancer, she set the stage for happiness and hope, she says, by such measures as surrounding herself with people who lift her spirits, keeping a daily gratitude journal, doing something good for someone else, and watching funny, uplifting movies. Her cancer has been in remission now for 12 years.

“Fostering positive emotions helped make my life the best it could be,” Harpham said. “They made the tough times easier, even though they didn’t make any difference in my cancer cells.”

While Harpham may have a natural disposition to see the hopeful side of life even when the outlook is bleak, new research is demonstrating that people can learn skills that help them experience more positive emotions when faced with the severe stress of a lifethreatening illness.

Judith T Moskowitz, a professor of medical social sciences at Northwestern University Feinberg School of Medicine in Chicago, developed a set of eight skills to help foster positive emotions. In earlier research at the University of California, San Francisco, she and colleagues found that people with new diagnoses of HIV infection who practiced these skills carried a lower load of the virus, were more likely to take their medication correctly, and were less likely to need anti-depressants to help them cope with their illness.

The researchers studied 159 people who had recently learned they had HIV and randomly assigned them to either a five-session positive emotions training course or five sessions of general support.

Fifteen months past their HIV diagnosis, those trained in the eight skills maintained higher levels of positive feelings and fewer negative thoughts related to their infection.

An important goal of the training is to help people feel happy, calm and satisfied in the midst of a health crisis. Improvements in their health and longevity are a bonus. Each participant is encouraged to learn at least three of the eight skills and practice one or more each day.

Moskowitz said she was inspired by observations that people with AIDS, Type 2 diabetes and other chronic illnesses lived longer if they demonstrated positive emotions. She explained, “The next step was to see if teaching people skills that foster positive emotions can have an impact on how well they cope with stress and their physical health down the line.”

She listed the goals as improving patients’ quality of life, enhancing adherence to medication, fostering healthy behaviours, and building personal resources that result in increased social support and broader attention to the good things in life.

Gregg De Meza, a 56-year-old architect in San Francisco who learned he was infected with HIV four years ago, told me that learning “positivity” skills turned his life around. He said he felt “stupid and careless” about becoming infected and had initially kept his diagnosis a secret.

“When I entered the study, I felt like my entire world was completely unraveling,” he said. “The training reminded me to rely on my social network, and I decided to be honest with my friends. I realised that to show your real strength is to show your weakness. No pun intended, it made me more positive, more compassionate, and I’m now healthier than I’ve ever been.”

In another study among 49 patients with Type 2 diabetes, an online version of the positive emotions skills training course was effective in enhancing positivity and reducing negative emotions and feelings of stress. Prior studies showed that, for people with diabetes, positive feelings were associated with better control of blood sugar, an increase in physical activity and healthy eating, less use of tobacco and a lower risk of dying.

In a pilot study of 39 women with advanced breast cancer, Moskowitz said an online version of the skills training decreased depression among them. The same was true with caregivers of dementia patients.

“None of this is rocket science,” Moskowitz said. “I’m just putting these skills together and testing them in a scientific fashion.” NYT
