Though many people think that positive thinking is mostly about keeping one’s head in the sand and ignoring daily problems, trying to look optimistic, in reality it has more to do with the way an individual talks to themselves. Self-talk is a constant stream of thoughts, often unconscious and negative about certain events, phenomenons, people, or even the person themselves. Negative self-talk undermines self-confidence and decreases self-esteem. On the other hand, positive thinking can help to stop negative self-talks and start to consciously form a positive view on an issue. People who regularly practice positive thinking tend to solve problems more effectively, they are less exposed to stress caused by outer factors, and believe in themselves and in what they do.
Positive thinking has several beneficial effects on the body and its condition of health. People who think positively demonstrate increased life spans, lower rates of depression and distress, better physical and psychological well-being, reduced risks of death from cardiovascular diseases, and other abilities (Mayo Clinic).
