Why do women have more colds than men?

In general, males seem to prefer cooler environments and females warmer. As Boris Kingma, a thermophysiologist, explains, there are several reasons why women are more sensitive to the cold.

First, they are usually smaller. This means they have a higher skin surface to volume ratio, so they lose heat faster.

They also have less muscle tissue (which burns more calories) and a lower metabolic rate (the process by which the body burns calories to produce energy) than men.

Smaller people's bodies have to react faster to protect themselves from cold temperatures. This is combined with the way a person perceives the cold and the discomfort this sensation can cause, adds the expert.

In addition, women tend to have a lower skin temperature, especially in the hands, which can make them feel colder compared to men.

A study published in the Lancet found that women's hands were colder than men's (about 3 degrees). This temperature difference results in the feeling of cold being more affected by skin temperature. Also, body temperature can change during perimenopause and postmenopause.

Declining estrogen levels can contribute to night sweats and hot flashes, said Jewel Kling, chair of the department of women's internal medicine at the Mayo Clinic in Arizona.
