A balanced diet with different nutrients, exercise that strengthens the body and supports circulatory and respiratory systems, and sufficient sleep to rest and grow are important healthy habits. Unhealthy habits include eating an imbalanced diet of fast food with little exercise which can cause weight gain, being exposed to allergens that trigger diseases like colds, overuse of technology leading to issues like weight gain and eye strain, and use of substances like alcohol and tobacco which seriously impact health. Maintaining good hygiene through practices such as hand washing before eating and dental hygiene are also highlighted.
