Human biology teacher Dr Niall MacFarlane, of the University of Glasgow, said previous research by two psychologists suggested skiing and snowboarding could make a person more attractive.
"The idea of excitement/fear being related to developing emotional attachments or love has been about for a long time," he said.
"The classic studies in this area stem from an original observation in 1974.
"Arthur Aron and Don Dutton showed that a young woman became twice as attractive to men under conditions that we might now describe as being 'extreme sports' - they were on rope bridges.
"This study lead to the idea that an 'adrenalin rush' associated with extreme sport will mimic the same feelings we experience during the early phase of physical attraction."
