According to research out of the United States, people in cold climates with less sunlight are more likely to drink heavily.
Researchers have found a link between average temperature and hours of sunlight and alcohol consumption.They examined data from 193 countries, leading to evidence that climate contributed to a higher incidence of binge drinking and subsequent liver disease.
Senior author Ramon Bataller, associate director of the Pittsburgh Liver Research Centre said the world first study systematically shows that worldwide and in The USA, in colder regions with less hours of sun, there is more drinking and more alcoholic cirrhosis.
This is probably not surprising given that alcohol is a vasodilator and relaxes blood vessels while increasing the flow of warm blood to the skin, so people are probably drinking to warm up.
Scientists have also linked drinking to depression which tends to be more common when sunlight is scarce.
