World's least and most stressful cities revealed

If you are one who likes traveling a lot and want peace of mind while traveling, places like Germany, Luxembourg, Switzerland and the UK is ideal for you, but if you think you are strong enough to withstand stress then, Lagos-Nigeria, Iraq and Afghanistan awaits you.

The ranking is based on factors including traffic levels, public transport, percentage of green spaces, financial status of citizens including debt levels, physical and mental health, and the hours of sunlight the city gets per year.

Of the 150 cities ranked, four out of the top ten most stress-free cities are in Germany with the southern city of Stuttgart coming out on top, Hanover in third place, Munich in fifth place and Hamburg in joint ninth place with Graz, Austria.

The tiny yet wealthy country of Luxembourg, home to fewer than 600,000 people, has the second-lowest stress levels.

Bern, Switzerland is fourth, while Bordeaux, France (No. 6) and Edinburgh, UK (No. 7) also make it to the top of the charts.

Sydney, Australia (No.8) is the only non-European city to make the top ten, while Seattle is the most chill US city.

The study, by UK-based dry-cleaning and laundry service Zipjet, was conducted by studying 500 locations based on data relating to 17 categories covering infrastructure, pollution levels, finance and citizens' well being.

Baghdad in Iraq is ranked as the overall most stressful city with a total score of 10 compared with Stuttgart's one -- followed by Kabul in Afghanistan while Lagos, Nigeria is ranked 3rd on the list.

The race equality category -- based on data from a World Bank ethnic inequality report -- is surprisingly, topped by cities in the US which see San Francisco, Boston and Seattle take the top three slots.

Glamorous, global cities such as London (No. 70), Tokyo (No. 72), Paris (No. 78) clustered around the middle of the league table, with New York (No. 84) being the most stress-inducing of the big four.
