While there are many physical benefits to good hygiene, there’s also an impact socially. People who take care of themselves in these ways tend to be more confident and have higher self-esteem. This boosts productivity at work or school, increases positive self-talk, and puts the person in a better mood. On the other hand, those who don’t practice good hygiene tend to have lower self-esteem and have increased thoughts of anxiety and irritability. It seems as though the saying holds true: look your best, feel your best!
