Otonamaki: wrapping oneself in cloth to ease pain

Otonomaki, or "Adult wrapping," sees the subject swaddled cosily, even tightly, in a muslin-like cloth. The aim is to "alleviate posture problems and stiffness," reports the BBC, and it's exploding in popularity in Japan.

"The reason why Otonamaki was invented was because some people were worried about babies struggling or feeling claustrophobic while being wrapped up," says Orie Matsuo of Kyoko Proportion, one of several companies that offer Otonamaki to its customers.
"We thought if adults were rolled up like them, they could experience how good it feels."
And if customer feedback is anything to go by, Otonamaki is certainly proving successful.

The psychological dimensions speak for themselves, whispering from within their calm white cocoon.
