Short people live longer than tall people, according to a new study. The scientists split subjects into groups based on body size, height, and ancestry, to test the hypothesis that short people live longer than tall people.
They found a considerable difference in longevity between the short and tall groups, and they proved that size is an inherited trait. The study started with 8006 Japanese men. During the study, their lifestyles and health conditions were carefully tracked.
What the science says about shorter people living
There’s been plenty of speculation about the relationship between height and life expectancy, but there is now some research that suggests the opposite is true: shorter people live longer than taller people.
In a study of 500 men born between 1866 and 1915 on the Italian island of Sardinia, scientists found that men who were under five feet four inches tall lived on average two years longer than their taller counterparts. Scientists suggest this may be due to less damage to DNA and increased heart pumping efficiency.
The exact cause is unclear, but researchers have uncovered a gene responsible for limiting body size during development. FOXO3 causes the body to stay contained during development.
The genes that regulate FOXO3 are associated with longer life, lower blood insulin levels, and lower incidence of cancer. This study is the first to show a direct link between body size and life expectancy.
It suggests that the gene may be a key factor in reducing cancer risks in short people.
But… why do shorter people live longer?
A recent study on the length of life suggests that shorter people live longer. The researchers examined the lives of 500 males born on Sardinia between 1866 and 1915.
The results showed that men shorter than 5ft 4in lived two years longer than their taller counterparts. Possible reasons for this relationship included less DNA damage, increased cell replacement potential, and more efficient heart pumping. However, the exact causes remain uncertain.
One of the factors contributing to longer lifespan is calorie restriction. Short men have lower fasting insulin levels, while tall men have higher levels. Also, the larger internal organs of tall people need more caloric intake per day, which may explain why shorter people live longer.
In addition, shorter men have fewer cells, whereas tall men have trillions of cells. They may also have lower levels of blood insulin, reducing the risk of developing cancer.
Health complications for tall people
A new study has suggested that being tall may increase your risk of several health conditions. Among them, varicose veins, heart disease, and nerve damage. But tall people also have a reduced risk of coronary heart disease, high blood pressure, and high cholesterol. Researchers looked at more than 1,000 conditions among tall people to determine the causes and risks.
Tall people also have a higher risk of skin and bone infections, blood clots, and nerve damage.
Some common health complications associated with being tall include peripheral neuropathy. This condition affects one in every ten Britons.
People with this condition experience pain, numbness, and tingling in their arms and legs. Because tall people have greater distances from their bodies, they are at higher risk of bone infections and leg ulcers. Tall people are also more likely to suffer from arthritis and other degenerative conditions of the joints.
What does this mean for tall and short people?
It’s common knowledge that the short person has a lower IQ and more leg room in airplanes. This can be an advantage, especially in sports. Yet the same is also true for tall people.
A new study published in the Journal of Behavioral Genetics is aiming to discover the genetic link between height and IQ. This research is particularly relevant to people who are prone to social shortness and those who have trouble adjusting to a short lifestyle.
In social situations, people make assumptions about a person based on their height. A tall man may be seen as too tall by a short woman. But a short woman may think the same of a tall man, who is likewise perceived as too short by the tall one.
Attractiveness is highly dependent on personality. In addition, it’s possible that both tall and short people are attracted to each other.
