Redheads can have a tough time of it as they go through life.
And now they face another blow – they could be more sensitive to pain than the rest of the population.
A trial is investigating whether pale-skinned and red-haired people react differently to pain.
And it could mean redheads need to be treated differently when receiving anaesthetics.
Researchers at Southampton University Hospital recruited redheaded volunteers aged over 30, anaesthetised them and gave them small electric shocks on the thigh.
