Hygiene is a matter of taking care of yourself. People who look good typically have amazing hygiene because they see themselves as something to groom and nurture. Depression can come out in poor hygiene for the exact same reason; if you don’t see yourself as something worth taking care of, you won’t take care of yourself.
Here are some good reasons to brush your teeth, clean yourself, shower, wash your clothes, and put on deodorant of some kind. One, when you take care of your body, it feels good. It may take effort and is a big hurdle for people, but after you do so, you psychologically feel better because you can’t feel or smell the grease and dirt any more. It’s easier to see yourself as handsome when you’re operating at your well-groomed level.
Two, you may not care about your body before a shower for example, but the physical act of washing cues our brain to see ourselves as something worth washing. Sometimes our thoughts cause our actions, but other times it’s our actions that cause our thoughts. And three, we care about other peoples’ opinions, and that’s not always a bad thing! We care about other people seeing us in a good light and that can motivate us to be better. You should want to take care of yourself and look good, but what we should want isn’t always what we actually want. That’s okay. Knowing the two previous reasons, the important step is being hygenic in the first place. Pick someone you care about mentally, from a parent to a friend to a dog to a celebrity, and take care of yourself for them. When we are clean, we are more confident, healthier, and more prepared for social situations. Some people struggle with it more than others, but the bottom line is that everyone is worth taking care of.
