The study involved 8,000 people who won big jackpots between 1994 and 2005. The researchers found that winning big led to serious long-term health problems because a jackpot winner has multiple party invites as well as ample opportunity to indulge in social drinking.
"Winning big does indeed improve mental health," said Andrew Clark, a researcher of the Paris School of Economics. "However, we uncovered counteracting health effects with respect to risky behaviours. Those who win more, smoke more and engage in more social drinking."
Dr Dorothy Rowe, a psychologist and author of The Real Meaning of Money, agreed, "You might think that if you get health problems you will be able to pay your way out of them by going to the best doctors," she told the Daily Mail.
The details of the study are due to be presented to an Institute of Social and Economic Research conference.
