Positive thinking and self-talk.
Positive thinking doesn’t mean that you keep your head in the sand and ignore life’s less pleasant situations. Positive thinking just means that you approach unpleasantness in a more positive and productive way. You think the best is going to happen, not the worst.
Positive thinking often starts with self-talk. Self-talk is the endless stream of unspoken thoughts that run through your head. These automatic thoughts can be positive or negative. Some of your self-talk comes from logic and reason. Other self-talk may arise from misconceptions that you create because of lack of information.
If the thoughts that run through your head are mostly negative, your outlook on life is more likely pessimistic. If your thoughts are mostly positive, you’re likely an optimist — someone who practices positive thinking.
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.
