Hygiene is important for several reasons. It positively impacts personal self-esteem and confidence by promoting a healthy body image. Good hygiene also signals a well-balanced diet that maintains healthy hair, skin, nails and teeth. Proper hygiene like hand washing helps prevent the spread of illnesses. Additionally, hygiene affects social and job opportunities because first impressions matter and are often based on appearance within the first few minutes of meeting. Maintaining good hygiene is beneficial for both physical and mental well-being.
