piggy, in fact i think our climate is the one that doesn't need confinement! Well, if you think abt it, confinement practice comes from China whereby there're 4 seasons. Also, such practices are passed down from the past where people drew cold water from the well (that's why must boil).
In SG, it's basically hot or very hot all year round. To me, doesn't make sense not to bathe. From TCM perspective (asked my TCM doc before I conceived), the not bathing part has no basis either..
