A group of scientists led by a professor of biology at the University of Turku – Markus Rantala – conducted a study whose purpose was to identify between the stress that a woman experiences and her attractiveness to the opposite sex.

Fifty-two women in their 20s were vaccinated against hepatitis B. Blood samples were taken from them to monitor their levels of cortisol, a stress hormone, and their immune response to the vaccine.

Then 18 men were asked to rate the attractiveness of each of the women in the photo. The men were unanimous and chose the ladies with the lowest levels of cortisol, while the strength of the immune system did not affect the male assessment of female attractiveness. But the presence of excess weight or painful thinness played a role.

Men liked the faces of women who were relaxed and at rest. Since our faces “broadcast” information about our state of health, both physical and mental. It is assumed that reduced fertility due to stress can be read by men and make them consider such a female face unattractive.
