Why Do Women Have Longer Lives Than Men

Everywhere in the world women live longer than men - but this was not always the case. The available data from rich countries shows that women didn't live longer than men in the 19th century. What is the reason women have a longer life span than men? What is the reason is this difference growing over time? The evidence is sketchy and زيوت تطويل الشعر we have only partial answers. While we are aware that there are behavioral, biological and environmental factors which play a significant role in women who live longer than males, we aren't sure the extent to which each factor plays a role.

In spite of how much number of pounds, we know that at least a portion of the reason why women live so much longer than men but not previously, has to relate to the fact that several significant non-biological elements have changed. What are the factors that are changing? Some are well known and relatively straightforward, like the fact that men smoke more often. Some are more complex. For example, there is evidence that in rich countries the female advantage increased in part because infectious diseases used to affect women disproportionately a century ago, so advances in medicine that reduced the long-term health burden from infectious diseases, especially for survivors, ended up raising women's longevity disproportionately.

The first chart below shows life expectancy at birth for زيوت تطويل الشعر men and women. We can see that all countries are above the diagonal parity line - this means in all countries baby girls can expect to live longer than a newborn boy.1

The advantage of women in life expectancy was smaller in rich countries than it is today.
Let's look at the way that female advantages in terms of longevity has changed over time. The chart below shows men and women's life expectancies when they were born in the US in the years 1790 to 2014. Two points stand out.

The first is that there is an upward trend. Both genders in America live longer than they did a century ago. This is in line with historical increases in life expectancy everywhere in the world.

Second, there's a widening gap: The female advantage in terms of life expectancy used be extremely small but it increased substantially during the last century.
