this is just like going to hot spring!! SO FUN!!
i'm gonna try this later..
can i put in those bath bombs?? so its not just plain hot water -.-
anyone wanna share what they would bring along with them when they do bahn sin yohk? haha
for me, i have this tokyo traveling (oh so popular in HK) and i'm gonna browse through that.. maybe bring my NDS along LOL
i think people should have an open mind as to what would work and what would not work.
there are many ways to lose weight and whatever so you know.. we all could be right or wrong. it doesn't matter.
just as long as you find it effective and that it works for you. bahn sin yohk has many other positive effects to the body so it's not just a weight loss thing.
people can put MILLIONS into slimming pills or go to slimming companies. yes, they could exercise instead of wasting their money? but you know what, it's their own choice.
So yea.. keep an open mind!! 
please don't get mad at me

(just stating my own opinions)
edit: didn't feel like making another post)
i tried it!!
but i think my water wasn't hot enough.. even though i ONLY turned on the hot water tap -.-
about 10 minutes into it, i started sweating..
around 20 minutes, my forehead had beads of sweat but they weren't like.. DRIPPING.
then a few minutes later, my back/chest were sweating. but it wasn't excessive sweating. (i'm gonna have to use hotter water next time)
i stopped at around 30 minutes because i began to feel a bit eh -.- . because sitting without getting my arms wet in our bath tub was so uncomfortable. haha
i didn't feel faint whatsoever. just felt refreshed

and i put in a bath bomb <33
