All people are born equal, but their appearances are different. Early studies have shown that good looks have natural advantages, and there is a certain relationship between appearance and job hunting, career development, and immune function. But no one would have thought that in addition to being able to make a living, appearance is also related to a person's lifespan.

Recently, the United StatesArizona State University、University of Texasof researchers in " Social Science & Medicine "The journal published an article entitled"Looks and longevity：Do prettier people live longer？ "Research paper.

research shows,Attractiveness was associated with mortality risk and life expectancy, with the least attractive people associated with a 17% increased risk of mortality. In addition, the least attractive men lived an average of one year shorter, and the least attractive women lived two years shorter.。

It is worth mentioning that,No significant difference in mortality risk between the most attractive and average-looking people。

In this study, researchers analyzed data from the Wisconsin Longitudinal Study（WLS）There were 8,386 participants in the cohort, 52.3% of whom were women. This was a survey of high school graduates who were followed up until their death or 80s. The attractiveness data was based on high school graduation photos. Trained raters rated the photos on an 11-point scale to analyze the association between attractiveness and mortality risk and life expectancy.

Overall, the attractiveness score of all participants was 5.43, and 43% of them died at the end of the follow-up period. The participants were divided into 6 groups based on their attractiveness scores, with the lowest 1/6 being the least attractive, the highest 1/6 being the most attractive, and the middle 4/6 being the reference group.

The analysis found thatThe least attractive people were associated with a 16.8% increased risk of death, however, there was no significant difference in risk of death between the most attractive people and those with average looks.。

In addition, for different age groups(20, 40 and 65 years old)The analysis found thatThe least attractive people have a higher risk of dying at every stage of life。

The analysis of different genders revealed thatWomen's mortality risk is more strongly linked to attractivenessAmong women, those with the lowest attractiveness had a 26.5% higher risk of death, which remained higher throughout the life course.

Not only that, the researchers also analyzed the impact of attractiveness on life expectancy.At age 20, the least attractive women could expect to live 1.89 years less, while the least attractive men could expect to live 0.86 years less.。

It should be emphasized thatThis is an observational study and cannot establish cause and effectThe researchers stressed that it is not clear why the findings were found, and more research is needed to further explore the causal relationship and mechanisms between attractiveness and mortality risk.

Still, the researchers say the findings highlight the potential impact of attractiveness on health. Beauty is only skin deep, but it's important to treat all people with kindness and respect, regardless of appearance.

As early as February 2022, the United StatesTexas Christian Universityof researchers inProceedings of the Royal Society B: Biological SciencesThe journal published an article entitled " More than just a pretty face？The relationship between immune function and perceived facial attractiveness "Research paper.

research shows,People with higher attractiveness tend to have stronger immune function, including stronger phagocytosis of certain white blood cells and stronger antibacterial immunity。
