반신욕 means half-bath.
You fill bathtub with very hot water but only high enough so if you sit down in it,it will only reach your belly button area.
And then you sit in it for as long as you can (try for 40 minute at least) but you can't get the upper part wet and must keep hands and top part dry.
The temperature difference between top and bottom parts of body make you sweat a LOT and afterward, you feel exhausted like you ran on treadmill.
Be careful when you do it and drink cold water after and get up carefully because you can faint..
You have to eat very healthy when you are doing this bath everyday to lose weight.
It is very popular in Korea and they even have spas and different products to put over the tub so you can do other stuff while bathing.
