Not going out during confinement

I’m quite an active person and soon to be FTM, and was wondering is it pantang to go out at all during the confinement period? Both my mum n MIL said NO cannot else will have “wind” go in, but I think I’ll be very depressed if totally can’t step out during 28 days. Of course, will prefer to recover n be with baby most of the time. But this feels like a superstition more than a recovery thing. Any thoughts?
