How can personal hygien be prevented?

It is not possible to prevent personal hygiene. Personal hygiene is the practice of maintaining cleanliness of one's body to reduce the risk of transferring potentially harmful microorganisms from one person to another and to avoid the spread of infection. It includes practices like regularly bathing, washing hands, brushing teeth, grooming hair, hand washing, and covering the mouth and nose while sneezing and coughing. Good hygiene practices are important for maintaining one's health, well-being, and protecting others from potential infections. The best way to ensure good hygiene is to form habits and routines that incorporate these practices.
