The Benefits of Happiness.

The feeling of happiness – whether you equate it with optimism, joy, well-being, personal achievement, or all of the above – goes hand-in-hand with healthier habits. People who are in good spirits tend to eat better, exercise more frequently, and get better sleep than those who are not. This could be because leading a healthy lifestyle helps you achieve your goals, which leads to happiness. It could also be that such habits lead to better health, which, in turn, lends itself to a better mood and contentment.
Beyond these rather common-sense associations, there’s something more about happiness that makes you healthy. It appears that a positive mental state may have a much more direct effect on your body. Positive thoughts and attitudes are able to prompt changes in your body that strengthen your immune system, boost positive emotions, decrease pain and chronic disease, and provide stress relief. Happiness, optimism, life satisfaction, and other positive psychological attributes are associated with a lower risk of heart disease. People with a deep sense of happiness and well-being have lower levels of inflammatory gene expression and stronger antiviral and antibody responses.
