Nowadays do you all follow the confinement rules? No bathing for a month? No washing hair? No aircon?

For #1 , my MIL wants me to follow strictly , so as to make my immunity stronger . I didn't bath for 2 weeks , wear long sleeves top , pant & a beanie , no air-con . After 2 weeks , bath thrice a week with warm water + herbs during the hottest time of the day , 12pm - 1pm . I was suffering . But after confinement , I do find that my body become stronger , not easy to fall sick compared to previously . For #2 , my MIL didn't ask me to follow strictly . She allows me to bath everyday with warm water + herbs & air-con too . My body remains strong . I'm not sure is it because of the strict confinement that I've been through .
