People in middle age who are always positive are known to have good cholesterol levels higher than the bad cholesterol. Good cholesterol protects the heart and fight bad cholesterol.
In addition, a positive person also has a low level of triglycerides. Triglycerides are molecules associated with hardening of the arteries. This was stated by scientists from the Harvard School of Public Health, as reported by the Daily Mail (06/03).
Scientists explain that this is most likely due to the positive attitude of someone that makes have and ideal weight and healthy diet. It was discovered after researchers conducted a study of 990 people aged 40 to 70 years.
Based on the interviews, participants who had high levels of optimism are known to have high levels of HDL (good cholesterol) levels. For every five points in the scale of optimism, increased blood HDL one milligram per deciliter. While any increase in HDL associated with a reduced risk of heart disease up to three percent.
Even so researchers do not see the link between positive thinking and the number of total cholesterol or LDL cholesterol. Moreover, when the researchers accounted for other factors such as diet and alcohol consumption, the relationship between positive thoughts and cholesterol is getting weaker.
However, researchers believe that people who are optimistic and have positive attitude tend to have a healthier lifestyle and have a healthy weight.
