Horrendous hygiene! how about you?
My hygiene is better than it used to be. I was particularly bad about brushing my teeth. I never brushed my teeth when younger and honestly don't know how I didn't notice how rank it was. Needed several fillings in my teens, but I still didn't really adopt a daily brushing habit until my 20s. Now I scrupulously brush my teeth twice a day. I find it the most boring task in the world, but I'm motivated to stick to it because I'm scared of losing my own teeth and ending up with dentures. As it is, I'm self-conscious about my teeth and wish I could afford the £1000s it would require to fully fix them up.
I shower every 2-4 days depending on what I'm doing. I don't know how people can have showers 2x a day; it would ruin my skin if I did that. Even showering once a day is too much for it. I have tried a daily shower and just ended up with blotchier, itchier skin and an exacerbation of the small patches of eczema on my face. Luckily I don't have a sweating problem, so I don't feel sweaty and grimy after 24 hours.
In between showers, I'll sometimes wash the areas more prone to smelling, e.g. armpits, crotch. I use an antiperspirant as well. I don't like being too hot, so I'm very rarely sweltering under layers of clothing.
