Yes, if not in the morn then in the eve, just take a shower everyday if you can pls, tired of smelling some of you mfs from across the room
Don't know, but I feel dirty if I don't take shower after sleeping even if its just a nap.
Yes, cause most of the time your body while resting is releasing a lot of things such as sweat, dead skin, and things like that... shower yourself :)
Yes if you're going out. Trust me, you'll smell bad even if it's a cold weather.
If you're staying home and live alone then it's up to you, I'd personally still shower
shower every friday and also after being in a state of sexual impurity (most likely before fajr prayer since, you cannot pray the compulsory daily prayers if you are in a state of sexual impurity without ghusl(ritual shower))
