I didn't do any confinement. Apart from being forced by my mum to cater confinement food, I looked after baby myself with hubby. I showered as usual, went out for walks, switched on the fan and air con, drank plain water and the stuff like that. I didn't see what was wrong with doing all the above as long as I remained sane and could breastfeed effectively.
My definition of confinement is, rest your body so that it can recover from pregnancy and birth, and eat nutritiously.
I'm doing fine, I have no body aches. Though people swear that by the time I hit 40, I would be aching all over, I think that if I watched over my health and had a healthy diet, I dont't see why my body would react that way. Body aching when you hit 40 happens to everyone whether you gave birth or not.
