Why Do Women Live Longer 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's the reason why women live longer than men? And why the advantage has grown over time? We have only a small amount of evidence and the evidence isn't strong enough to make an unambiguous conclusion. We know there are biological, زيوت تطويل الشعر, glorynote.com, behavioral and environmental variables that all play a role in women living longer than men, we do not know how much each one contributes.

We have learned that women live longer than males, regardless of weight. However it is not because of certain non-biological aspects have changed. What are these changing factors? 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.

Everywhere in the world women tend to live longer than men
The first chart below shows life expectancy at birth for men and women. As you can see, every country is above the diagonal parity line ; it means that in all nations baby girls can expect to live longer than a new boy.1

Interestingly, this chart shows that the advantage of women exists everywhere, the difference between countries is huge. In Russia women have an average of 10 years more than men. In Bhutan the gap is just half each year.

In wealthy countries, the women's advantage in longevity was previously smaller.
Let's examine how the female longevity advantage has changed in the course of time. The following chart shows the male and female lifespans at birth in the US from 1790 to 2014. Two specific points stand out.

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

Second, the gap is widening: While the advantage of women in terms of life expectancy was very small It has significantly increased with time.
