, co-founder of Morning Gloryville, said dancing to loud music in the morning releases endorphins and serotonin which, like as with a gym workout, produces a natural high: "It can boost creativity and increase productivity – but it is so much more. It helps us get close to one another and be more like friends."

Sam and her co-founder Nico Thoemmes launched Gloryville in Shoreditch, London, in May last year and now has pre-work raves in 11 countries round the world. Its Â鶹¹û¶³´«Ã½ branch opened earlier this year at Shoosh in Kings Road arches.

Sam, who was awarded a foundation degree in business and marketing at the University of Â鶹¹û¶³´«Ã½, said: "We have now spread the 'glory' around the word, to New York, San Francisco, Amsterdam, Paris, Barcelona, Zurich, Sydney, Tokyo – and we are planning to launch in Liverpool and Melbourne.

"There's a growing desire, a global shift in consciousness, towards mindfulness and direct human experiences – and so there is a huge appetite for the kind of authentic, healthy and fun experience Morning Gloryville creates.

"It's something that puts a spring in one's step and softens the daily grind."

One Â鶹¹û¶³´«Ã½ raver Frances Jones, a communications executive, said: "I thoroughly enjoyed myself and it gave me a great lift. I loved the fact that everyone is welcome, from office workers to pensioners. Really recommend it."

An accountant said: "The one difference from a normal rave, apart from it being in the morning and not late at night, was that there was no alcohol – only healthy, soft drinks. I loved it."
