Introduction:
Hygiene is a set of habits and practices that people follow to stay clean and healthy. It helps prevent diseases and keeps our bodies and surroundings clean. The World Health Organisation (WHO) says that hygiene is important for protecting our health and stopping the spread of germs and diseases.
Maharashtra State Board: Class 5
The Importance of Hygiene for Health and Well-being:
- Prevents Diseases: Good hygiene habits, such as washing hands frequently, are scientifically proven to reduce the transmission of infectious agents like bacteria, viruses, and fungi.
- Protects Others: Proper hygiene reduces the risk of spreading infectious diseases to others. Respiratory hygiene, such as covering the mouth when coughing or sneezing, limits the transmission of airborne pathogens.
- Promotes a Healthy Environment: Keeping homes, schools, and public spaces clean reduces the accumulation of dust, mould, and harmful microorganisms. A hygienic environment promotes better air and water quality, contributing to overall health.
