Introduction to Health and Lifestyle

Health and lifestyle are closely connected. A healthy lifestyle involves making choices that benefit physical and mental well-being, like eating nutritious food, exercising, avoiding harmful substances, and managing stress. Our daily choices impact our overall health, influencing how well our body functions and how we feel. Understanding the basics of health and lifestyle is essential for developing habits that can improve life quality and reduce the risk of diseases.

Key Concepts in Health and Lifestyle

1. Balanced Diet: Eating a variety of foods to get the nutrients your body needs, including carbohydrates, proteins, fats, vitamins, minerals, fibre, and water.
2. Exercise: Physical activity is vital for maintaining a healthy body weight, improving mood, and supporting heart, muscle, and bone health.
3. Harmful Substances: Avoiding substances like alcohol, tobacco, and drugs can help prevent damage to organs, reduce addiction risks, and lower chances of developing diseases.
4. Mental Health: Taking care of mental well-being is just as important as physical health. Managing stress, sleeping well, and having a positive outlook contribute to a healthy mind.
5. Risk Factors for Disease: Poor lifestyle choices, such as a high-sugar diet or a lack of exercise, can increase the risk of diseases like obesity, heart disease, and diabetes.

By understanding how lifestyle choices affect health, students can make informed decisions about their well-being.
