Optimism and Health: A Delicate Balance
New research suggests a strong link between optimism and improved health, but warns that excessive positivity can be detrimental. A study from the Technical university in Haifa, involving mice, indicates that positive expectations trigger the release of substances that bolster the immune system. While it remains to be seen if this mechanism operates identically in human beings, the findings add to a growing body of evidence connecting mindset to well-being.
Statistically, optimistic individuals tend to lead healthier lifestyles, engaging in more sport, consuming less alcohol, avoiding smoking, and paying closer attention to weight management. However, researchers are still debating whether optimism *causes* better health, or if healthy and prosperous people are simply more inclined to be optimistic.
The relationship is highly likely bidirectional, with optimism contributing to good health and good health fostering optimism. but neuroscientist Tue Share, from University College London, cautions against unchecked positivity. In an article published in the magazine “Cell,” Share warns of the dangers of excessive optimism.
“excessive optimism may push people to ignore the necessary precautions,” Share explains. “The optimistic assumption that one will not develop lung cancer or face bankruptcy, for example, it may encourage potential harmful behaviors such as smoking or excessive spending.”
A Canadian study highlighted a particular risk for older adults. Those who unrealistically believe their health will remain stable or improve with age are not only more susceptible to depression but also face a higher risk of early mortality. This suggests that accepting the realities of aging and preparing for potential health challenges is crucial for well-being.
