Money, self-pressure and lack of sleep are the top three major causes of stress across the world, it has been revealed.

According to a 22-country survey from GfK, money is the main source of stress for 29 percent of people. Putting pressure on oneself is the second-biggest cause of stress, with 27 percent of respondents citing this as their main worry. Finally, sleep deprivation is a source of stress for 23 percent.
