I live in Canada. In the summer I'll shower every day, almost. Except days where, like you said, I stayed in with the AC on all day. Then I'll shower the day after.

In the winter I'll shower every two days. Or when I'm really cold and need some extra warmth.

I live in Wyoming. In the winter I bathe once or twice a week simply because it is so cold and dry that I don't sweat. If I bathe too much my skin will dry and crack in the cold dry air, which is not pleasant. Notice, I said bathe instead of shower. That's because if I am going to skip a few days, I need to make sure that I properly scrub off the dead skin. Dead dry skin can also lead to painful cracked skin. Wyoming winters don't fuck around.

In the summer it can get very dusty so skipping a shower is a rare thing. Hell, sometimes I have to wash the dust off my face multiple times a day.

EDIT: Grammar fixes

Depends on weather. In summer I usually shower at least once a day. Peak heat wave it was 4 times because I just could't function like that. Winter... depends, but often it's every other day, depending how I feel.

At home it's just part of my wake up routine to take a shower. I do it in the morning.

On holidays, like cycling holidays i may end up not taking a shower for a week even though i'll be sweating my ass off every day. I don't feel like i smell terrible then, and i have not gotten the vibe ever that somebody else thought i did. I use deo though and do some 'cat wash'.

I shower every day because it feels nicer when I go to bed. With alopecia I got really sensitive to how sticky the skin gets, probably because there's not even a tiny push fuzz left. I only use shampoo every other day though.

Where do you live, and do you no exercise? I walk to work, get a ride home, go to yoga or take a long Pokemon Go walk or lift weights, no way am I crawling into bed without a shower.

If you are dead idle and living in a cold dry place, sure. But I don't think that is most of the world.

ETA: I saw the comment below about rinsing, not washing. I am not using soap everywhere every day, no. More of a rinse off.

I have a disability and cannot not shower every morning. It's also 35-40 degrees here most of the year. I cycle around town. I also don't need much water, I get myself wet, put shampoo, rinse, turn tap off again, lather, on, face was, rinse, off. I probably use five litres or less than that.

I don't see the point either. Now in winter for example I'm taking, like, 4 showers a week - I never skip two days, but I'm not going all the way to shower religiously every single day either.

I’ve been a once a week person these days and I have no problem with it. I don’t leave the house much and should prob exercise more though dangit.

I like having a shower. It's nice.

Gross. Have an upvote.

I work from home for my main job (desk job) and still sweat; I also try not to over-use my air conditioning. Additionally, I have to mow (though the goal is to continue reducing grass in favor of edible plants, it takes time), do other work around the house, and do small-scale farming.

All of that nonwithstanding, I've gotten into the habit here in Japan of not getting in to bed dirty. I don't wash my sheets every single day, so I wash me before getting into bed rather than stewing in bacteria, fungi, pollen, etc. for a week or more at a time. Additionally, a hot bath before bed helps me relax and get ready for sleep (though I skip it sometimes in the worst parts of summer). My sleep quality is also now better than it used to be.

I shower every other day and feel fine, except on the hotest days in summer

My skin and hair are to sensitive. I'd like to shower every day, but my skin doesn't do very well when I do

Going swimming during summer months counts as a bath, right?

yes and no, IMO it's probably best practice but not really necessary to shower with only water every day, but it's definitely not needed to also use products every day, unless you work with stuff that gets on your body and actually needs soap and shampoo to come off.

For the average person i'd say shower with soap once per week and then just rinse with water and scrub yourself down whenever you feel the need.
