I shower every morning post-first dog walk, and again every evening - I exercise or go for a run most evenings, and I have dogs that I walk 2-3 times a day, every single day, and I can't stand feeling grubby or sweaty. The thought of going for more than 24 hours without a shower gives me the shudders unless I'm wild camping or on a multi-day hike, and on those occasions I baby wipe like a demon and am first into the showers on return! Run razor over legs most days, pits every day, bikini line and eyebrows are waxed once a month. Moisturise body after every shower, I love the new spray-on jobs, face morning and evening.
Cleaning teeth, absolute minimum is twice a day but 99% of the time it's 3 times. Mouthwash and floss every night. No matter how late I get home I brush my teeth and take make-up off, I wouldn't be able to sleep without doing it. Hair is washed every other day, or every day if I've had a particularly sweaty run/work out. Knickers changed twice a day, morning and evening, clean socks every morning, t-shirts/tops worn once. Exercise/running clothes - top, shorts/capris, bra, socks, kecks - thrown in wash immediately on return every day - I have 4 or 5 sets. Normal bras worn twice. I have a lot of jeans which I wear on rotation so generally will wash every 2-3 wears but that could be weeks apart. Hoodies/jumpers generally every 2 wears but it depends what I've done while wearing them. Towels and bedding washed twice a week - there is nothing better than a clean bed!
I don't think I'm excessive re. cleanliness, it's just normal maintenance to me; I know that most of my friends/close colleagues have similar routines and frankly, the people I come across that don't wash themselves or their clothes, or brush their teeth every day, you can tell. I can't stand feeling dirty or the thought of people thinking that I look or smell unclean. It just feels nice to be clean and fresh, and to live in a clean house - I can't bear dirty houses either!
