London: Something as simple as carrying heavy shopping bags can trigger depression reveals a study. In the study, one group of participants were told to hold shopping bags full of goods before giving their opinion on an unrelated topic. Another group was left empty-handed and questioned.
 
Results showed the issue was more important to those carrying bags than those who were not weighed down, the Journal of Consumer Research reported.
 
Researcher Meng Zhang and Xiuping Li, from the Chinese University of Hong Kong and National University of Singapore, said their findings suggest physical weight influences a person's psychological weight, according to reports..
 
The study found that negative psychological impact was eliminated when participants who carried heavy loads were instructed to think about light objects, such as balloons and feathers.
