Key points
- Good health behaviors promote a stronger sense of coherence, and higher levels of optimism and self-efficacy.
- Pleasurable activities can change your gene expression for the better. The opposite also applies.
- If you want your friends and colleagues to like and respect you, feel good about yourself.
According to a new study from the University of Helsinki, classical music fans, when listening to Mozart’s violin concerto No. 3, G-major, were found to upregulate the activity of their genes involved in dopamine secretion and transport, synaptic neurotransmission, learning and memory, and down-regulate the genes mediating the destruction of neurons, which is all for the good. What this means is that if you find something pleasurable, it can change your gene expression. Not Mozart per se.
How we live our lives can have significant effects on how we age and develop diseases including cancer. On the physical side of the equation, if we look at colon cancer, researchers from the University of Basel found that aspirin and hormonal replacement therapy reduced the methylation rate of colon cancer related genes, whereas smoking and high body mass index (BMI) increased it.
Steve Cole, Professor of Medicine, Psychiatry and Biobehavioral Sciences UCLA School of Medicine, has written much on the subject of self-regulation. He holds, and I totally agree with him, that we are architects of our own lives more than we realize. Our subjective experience carries more power than our objective situation. If we feel good about ourselves, not only will our health improve but so will our relationships. As a result, our friends and colleagues will like and respect us, which in turn will make us feel even better about ourselves. Thus, we create a self-reinforcing reward system grounded in epigenetics.
A study from Oregon State University on aging found that how people thought about themselves at age 50 predicted a wide range of future health outcomes up to 40 years later -- cardiovascular events, memory, balance, will to live, hospitalizations, even mortality.
In general, optimistic people live longer than pessimistic people. A thorough review of the medical literature to determine the strength of the association between optimism and physical health revealed that optimism was a significant predictor of health outcomes in cardiovascular disease, including immune function, stroke, cancer, complications related to pregnancy, physical symptoms such as pain and risk of disease.
People who feel enthusiastic, hopeful and cheerful – what psychologists call 'positive affect' – are less likely to experience memory decline as they age. It does not necessarily mean they will never get ill (mentally or physically), but optimists diagnosed with bipolar illness are able to manage the disease better than pessimists. A recent meta-analysis confirmed these associations.
A recent study from Poland explores the relationships between psychological variables such as health behaviors (HB), sense of coherence (SOC), level of optimism (LOO), and self-efficacy (SE) among 455 college students. These separate measures were used to create a novel construct of positive health attitude (PHA).
The results indicate statistically significant differences (p<0.001) between these four variables: for example, healthier health behaviors lead to a stronger sense of coherence, level of optimism and self-efficacy. Self-efficacy beliefs determine how people feel, think, behave and motivate themselves.
These and many more studies add to a growing body of research on the contribution an optimistic outlook makes to health.
Of course, I am not suggesting a “fake it till you make it” attitude. Cultivating creativity, imagination, self-reflection, living a meaningful and engaged life takes work but is an investment in our overall well-being — and potentially the well-being of our children.
