Now today we will show you why women are live more than man.
Key Points
Worldwide, women outlive men, and scientists have mostly connected these sex-based disparities in longevity to biological factors that contribute to survival. Significant variations in lifespan and aging have been discovered in different mammalian species, according to a recent study of wild mammals.
In humans, women typically live a little more than 8% longer than men. But in 60% of the examined species of wild animals, females live 18.6% longer on average than males. For several mammal families, the ratio varies significantly.
For 134 populations of 101 wild mammalian species, a global team of researchers led by Jean-François Lemaître from the University of Lyon 1 in France gathered data on age-related mortality.
Lemaître reported that the gender gap in lifespan “was surprising to observe, as it often exceeds the one observed in humans while being, at the same time, extremely variable across species.”
For instance, according to one of the study’s authors, Tamás Székely from the University of Bath, lionesses live at least 50% longer in the wild than male lions.
“Our statistics do not support this,” said Székely. “We previously thought this was primarily due to sexual selection—because males struggle with one another to overtake a pride and so get access to females.
The probability of death does not rise more quickly in males than in females across species, despite the fact that females routinely outlive males. They contend that other, more complicated elements must be at work, such as the animals’ living environments and the evolution of sex-specific development, survival, and reproduction over the history of the species.
For instance, roving males may be exposed to more environmental infections, according to the study’s authors. Three populations of bighorn sheep showed this, according to research.
The balance between reproduction and survival in the local environment may also have an impact on the size of the lifetime disparity. According to scientists, males in some animals devote more energy to sexual competition and reproduction, which could result in greater lifespan disparities between the sexes.
Another explanation for the gender gap, according to Székely, is that female survival rises when males take on most or all of the parental responsibilities. If both parents cooperate in raising their children, the health costs associated with childbirth and childcare are decreased for females.
Scientists intend to compare the data on wild mammals with the data on mammals maintained in zoos, where they are not required to engage in combat with predators or compete for food and mates, in order to gauge the extent to which biological differences between the sexes affect life expectancy.
The results, according to scientists, should improve knowledge of the factors influencing human longevity. Humans now live longer on average than they did 200 years ago, thanks to better living conditions and medical advancements. Despite this, women continue to outlive men, indicating that biological differences may possibly play a part.
The average American man will live to be 76 years old, while the average American woman will live to be 81 years old, according to the US Centers for Disease Control. In their later years, women can anticipate being in better health than men. Experts have stated that a combination of biological and social variables is to blame for the divide.
As men age, the hormone testosterone is associated with a decline in their immune systems and an increase in their risk of cardiovascular diseases. It also has a connection to dangerous behaviors like drinking, smoking, and unhealthful eating patterns. Men are less likely than women to heed medical advice after being diagnosed. According to statistics, men are more likely to take dangerous actions and pass away in vehicle accidents or gunfights.
According to the current study’s authors, complex interplay between regional environmental factors and sex-specific reproductive biology explain the disparities between male and female longevity. According to their predictions, more study will likely yield “innovative insights into the evolutionary roots and physiology underlying aging in both sexes.”
According to a study
A team of researchers from Harvard Medical School found that both nature and genes play a role in why women live longer than men.
It runs in the family!
Although men and women share 22 of the 23 chromosomes, the 23rd pair differs, according to Harvard Medical School. Males have one X and one Y chromosome, whereas females have both of the 23rd pair of X chromosomes. Some chronic disorders are associated with the Y chromosome, which has fewer genes than chromosome X. Men experience a greater mortality rate as a result.
Hormones also have an impact.
The hormone testosterone significantly contributes to men’s weakened heart muscles and increased risk of heart disease. Men have a 50% greater risk of dying from heart disease than women do. Contrarily, the estrogen hormone guards against heart failure in women.
Also subject to spoilers are reproductive organs.
Men are generally more susceptible to cancer because of the prostate gland, but women are more vulnerable to certain forms of cancers such breast, uterine, and cervical cancer.
Women’s metabolism is better.
The ‘good cholesterol’ (60.3 mg per deciliter) that women have in abundance improves their heart health. Additionally, this reduces the likelihood that women would develop lifestyle disorders like diabetes and obesity.
Less risk-averse than men are women.
Males have a less developed frontal lobe of the brain, which affects our capacity for judgment and analysis. This could be one of the factors contributing to the majority of accident victims being male. This could also be a contributing factor in why so many guys abuse alcohol or smoke excessively.
