Researchers continue to explore the effects of positive thinking and optimism on health. Health benefits that positive thinking may provide include:
  • Increased life span
  • Lower rates of depression
  • Lower levels of distress
  • Greater resistance to the common cold
  • Better psychological and physical well-being
  • Reduced risk of death from cardiovascular disease
  • Better coping skills during hardships and times of stress
It's unclear why people who engage in positive thinking experience these health benefits. One theory is that having a positive outlook enables you to cope better with stressful situations, which reduces the harmful health effects of stress on your body. It's also thought that positive and optimistic people tend to live healthier lifestyles — they get more physical activity, follow a healthier diet, and don't smoke or drink alcohol in excess.
