Man flu does exist: Chaps 'run a higher temperature and feel rougher' when they are fighting off a bugNeuroscientist says men really

It's often seen as nothing more than whinging about a cold.
But ‘man flu’ really does exist, according to research.
Men suffer more with coughs and colds because they have extra temperature receptors in the brain and so experience worse symptoms.
Neuroscientist Dr Amanda Ellison says men have more temperature receptors in the brain which causes them to experience the symptoms more acutely than women
Children deal with colds the same way
because the relevant area of the brain is the same size in boys and
girls, said Durham University neuroscientist Dr Amanda Ellison.
But when boys hit puberty testosterone starts to act on the area, called the preoptic nucleus, making it larger.
Dr Ellison said: ‘When you have a cold
one of the things that happens is you get an increase in temperature to
fight off the bugs.
‘The bugs can’t survive at higher temperatures.
‘When your immune system is under
attack the preoptic nucleus increases temperature to kill off the bugs.
But men have more temperature receptors because that area of the brain
is bigger in men than women.
‘So men run a higher temperature and feel rougher – and if they complain they feel rough then maybe they’re right.’
Research published in 2009 which also
supported the existence of man flu was criticised as inconclusive as it
related to genetically engineered mice rather than humans. But Dr
Ellison’s study was based on research carried out on human brains.
‘It is part of the whole argument
about the differences between men and women and how their behaviour can
be influenced by differences in their brains,’ she added.
Commenting on the fact that her
findings could be seen as controversial, Dr Ellison said: ‘I’m just
throwing it out there. The debate will rage on and quite rightly so. The
trouble with man flu has always been that there is not much hard
evidence that the feelings are worse in males than in females. This is
just a possible cause.’
