The practices of personal hygiene contribute to good health. Personal hygiene helps in protection against some of the infectious diseases such as typhoid, cholera, and dysentery. The practice of hand washing is often forgotten by many people yet it is one of the ways to prevent a plethora of diseases and disorders from developing (Sivarethinamohan 331). The use of unclean hands may make one, for example, contract diseases such as cholera or diarrhea. The hands should always be washed thoroughly before eating or preparing the meals so as to avoid contamination of the meals and hence minimize the development of the diseases related to the same.

Furthermore, the act of washing the hair or shaving the hair helps to minimize some of the diseases such as dandruff. According to Sivarethinamohan (331), untidy hair is always a hiding and breeding place for lice and these should be well treated to prevent spreading and consequently affect others especially in the learning institutions or the family members. Generally, the skin plays a significant role in protecting the body against infections (Sivarethinamohan 330).

For these reasons, the skin should be cleaned regularly so as to keep it clean and stronger enough to fight infections and effectively protect the body. During the perspirations, for example, the sweats contain urea which ends up as deposits on the skin surface thus necessitating the cleaning of the skin through bathing. Sivarethinamohan (331) cites that some of the skin diseases such as the athlete’s feet could be prevented by proper hygiene.

On the other hand, the brushing of the teeth is equally significant health-wise. The teeth should be brushed at least after every meal. This helps in preventing teeth decay and other dental infections such as gingivitis and periodontal diseases. Such diseases are responsible or may contribute to halitosis. Besides the teeth, in most cases, the fingernails also form hiding sites for germs causing diseases. The debris under the unclean fingernails contains microbes that lead to the development of diseases.
