Britons have revealed that they would rather talk about their weight than their personal finances.
A survey of 2,000 adults has found that Britons think it is socially unacceptable to talk about sex, debt and mental health.
Just 18 per cent consider the delicate topics of miscarriage and infertility to be off-limits compared to one quarter who say the same about personal finances.
The research commissioned by finance company Lowell found one in five also admitted that they do not think it is suitable to disclose their salary in social settings.
Other unacceptable conversations include drugs, sex and parenting techniques, with Britons saying that discussing these “taboo” subjects leaves them feeling “anxious”.
Clinical and counselling psychologist Tamara Licht Musso said: “Not talking can seem the best short term strategy, but is a negative coping mechanism and at some point it cracks.
“Avoidance is also a classic way of coping to keep anxiety at bay, but we cannot avoid our thoughts therefore pushing back such thoughts may result in them appearing through symptoms such as difficulties with sleep.
“Taking the ‘easy’ route might seem to be the answer because the rational path – talking - puts us in a much more vulnerable position.
"In the short term this may be true, but it puts us in a healthier place in the long term.
“The fear of being judged is based on distorted thinking patterns such as jumping to conclusions and mind reading.
“For example, some people will think that by sharing their salary others may misjudge their ability.”
The research conducted by OnePoll also found more than half fear being judged if they were to open up about personal issues, while another one in two avoid certain topics because they find it “embarrassing”.
