grewing up in germany I also remember that my parents/grandparents regularly went "on a cure" somewhere in germany (on top of vacation), often somewhere near the sea, which where prescribed and paid partially by health insurance ("parent-child-cures" where also quite common).
that somehow changed a lot in my generation...
protip for the german people here... you can claim up to 10 days "bildungsurlaub" every 2 years (in some states paid/in some unpaid) and yoga retreats or similiar are also possible ;)
