I used to be hardcore about taking atleast 2 showers a day, one in the morning when i wake up, and one at night when I go to sleep. But in the past I was also very active. Played lots of Hockey in tournaments constantly for various teams, basically playing hockey 7 days a week travelling all over the south east united states and sometimes much further. I was always playing various sports and always sweaty, so I took like 2 showers a day minimum.
Over the last 10 years or slow, I have become a lot less active, no longer participate in sports etc. The most intensive exercise I get is going to the nightclub once a week to dance, and DJing house parties etc...
I have also gone through a lot of depressing periods of my life where I was unable to get the energy to even walk down the stairs of my apartment that i lived in at the time....
As a result of all this I have really stopped giving a shit about taking a shower all the time. I just recently went over a week (almost 2 weeks) without taking a shower.
Granted, I work from home, on the phone, siting in my computer desk in my boxers alone (which i change every day)
I didnt really need to take a shower but I went to the club thursday so before I went I took a shower. (I also took one after I got home)
I have a very large afro that litterally requires its own towel to dry. (not to mention about 15 minutes to wash and dry just the fro) So I am in the process of finding the right balance between showering and not showering.
I think 3 to 4 days is probably the longest one should repeatedly go without a shower , and thats probably only if they are in a situation like me where they are sitting at home in their underwear all day.
But I did survive just recently 12 days without a shower.... I dont plan on doing that again anytime soon though... lol
