Swaddling as a form of therapy

Otonamaki (otona = adult, maki - wrapping) is the practice of swaddling adults in cloth to relieve stress.

From BBC:

"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."
