Women have long moaned about the men in their lives coming down with “man flu” and turning into feeble, moaning boys. But according to a new study, there is actually some truth to the idea of man flu.
It all comes down to our cavemen ancestors – men have weaker immune systems than women which used to be in order to stop them going out hunting when ill.
Some studies, he adds, have also suggested that testosterone may suppress the immune system, pointing to a potential evolutionary basis for man flu. Strength and virility were once more important than immunity for testosterone-charged men, he writes, who were likely “to die from trauma before an infection kills them.” By that logic, man flu could even be a defense mechanism, keeping weakened men laid up and away from predators and competitors during the recovery process.
