In this era of jet lag, back-to-back meetings and 24-hour technology, the hotel spa has never been more important to the global business traveller.
And for the leisure tourist there's nothing quite like being massaged into a jelly-like state and feeling all your cares drift away at a resort's spa.
In a 2012 survey commissioned by Hilton Hotels and Resorts, nearly half of respondents said the existence of a hotel spa was an important factor in choosing where to stay.
Chinese travellers, in particular, were the most likely to factor in whether a hotel has an on-site spa in their booking decisions, followed by Australians, the survey of 6000 global travellers found.
Of the Chinese travellers polled, 84 per cent said the inclusion of a spa was important in the decision to choose a particular hotel, compared with 52 per cent of Australians, 37 per cent of Britons and 32 per cent of Americans.
"Hotels are much more than a place to sleep," Hilton Hotels and Resorts global head Dave Horton said at the launch of the paper in Sydney this month.
"Hotels worldwide are increasingly finding that spas can drive guest bookings."
In regards to spa treatments, Chinese tourists wanted more "results-orientated treatments", such as those meant for detox, blood circulation and weights loss, while Australians placed emphasis on treatments that focused on relaxation and stress reduction.
The research also highlighted the growing importance of men to the global spa industry.
"The assumption globally that the spa market is overwhelmingly female is simply not true," Hilton Worldwide global spa senior director Tyra Lowman said. "Especially in urban hotels and those that cater to business travellers, the gender split is often closer to 50-50."
The needs of the male spa guest are very different than those of the female visitor, she says.
Generally speaking, men prefer a no-nonsense approach to their spa experience and want to know that the treatment they select will ultimately be effective.
"Men tend to be loyal spa-goers," Ms Lowman said.
"If they are provided with their desired results, they are likely to return."
