Sun-seeking behaviour is linked to genes involved in addiction, behavioural and personality traits and brain function, according to a study of more than 260,000 people led by TwinsUK researchers.
This means that people’s behaviour towards seeking sun is complicated by a genetic predisposition, and this needs to be taken into account when designing skin cancer awareness campaigns.
The researchers studied detailed health information of 2,500 twins from TwinsUK, including their sun-seeking behaviour and genetics. Identical twins in a pair were more likely to have a similar sun-seeking behaviour than non-identical twins, indicating that genetics play a key role.
The team then identified five key genes involved in sun-seeking behaviour from a further analysis of 260,000 participants from other cohorts. Some of these genes have been linked to behavioural traits associated with risk-taking and addiction, including smoking, cannabis and alcohol consumption and number of sexual partners.
