3.3. Health and Fitness

According to World Health Organisation (WHO) ‘‘Health is the state of complete physical, emotional, and social well-being, not merely the absence of diseases or infirmity.’’ This definition has remained unchanged since 1948.

Health is more than just not being sick. The WHO defines health as being completely well physically, emotionally, and socially. This means you are not only free from illness but also feel good mentally and can interact positively with others. Think of it like this: if someone can run a marathon (physical well-being), feels happy and stress-free (emotional well-being), and has a supportive group of friends (social well-being), they are considered healthy.

Imagine a flower. For it to bloom beautifully, it needs healthy soil (physical health), enough sunlight (emotional health), and space to grow without competition from other plants (social health). Just like the flower, a person needs balance in all three areas to truly be healthy.

Physical health is probably the most easily understood aspect. Mental health can be defined as a state of emotional and psychological well-being in which an individual is able to use her or his cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life.

Physical health refers to how well our body functions. It is the foundation on which we build our overall health. If someone is physically strong, they can perform daily tasks effectively. Mental health, on the other hand, relates to our emotional and psychological state. It includes being able to manage stress, maintain relationships, and handle life's challenges. For instance, if one is physically fit but feeling stressed or anxious, they might not perform well at school or work.

Consider a smartphone. It can run very well if the battery (physical health) is charged. But if it's clogged with too many apps and running slowly due to lack of updates (poor mental health), it won't perform to its potential. Similarly, our bodies need both physical and mental health to function optimally.

Physical fitness is good bodily health; it is the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery.

Physical fitness means that your body is in good shape and can perform various activities without getting tired easily. It results from a combination of regular exercise, a nutritious diet, and adequate rest. Exercise strengthens muscles, improves heart health, and can enhance mood. Eating well fuels the body with energy and essential nutrients, while rest allows for recovery. For example, someone who exercises regularly and eats a balanced diet will generally have more stamina and be less susceptible to illness.

Think of an athlete preparing for a competition. They train rigorously (exercise), eat healthy foods like lean proteins and fruits (nutrition), and ensure they get plenty of sleep (rest). This combination prepares them to perform at their best during the event, just like anyone else striving for good health should do.

Physical fitness can also be divided into five categories: aerobic fitness, muscular strength, muscular endurance, flexibility, and body composition.

There are different types of fitness that contribute to overall physical fitness. Aerobic fitness helps the heart and lungs work better; muscular strength refers to how much weight you can lift; muscular endurance is how long you can use your muscles without getting tired; flexibility is how much you can stretch; and body composition relates to the proportion of fat and muscle in your body. Each category is important for different activities, like running, lifting, yoga, or maintaining a healthy weight.

Consider a well-rounded athlete who excels in multiple sports. For instance, a soccer player needs aerobic fitness for running, muscular strength to power through tackles, endurance to keep playing for the full match, flexibility to avoid injuries, and a good body composition to maintain peak performance. Each aspect of fitness contributes to their overall ability to perform.

Thus, health is a state of complete mental, physical, and social well-being whereas fitness is the ability to meet the demands of a physical task.

Health includes all aspects of well-being—mental, physical, and social. Fitness, however, is specifically about how well you can perform physical tasks. Good fitness can enhance your overall health by improving your body’s efficiency and reducing your risk of diseases. For instance, regular exercise not only strengthens your body (fitness) but also improves mood and reduces stress (mental health).

Think of a car. If it's well-maintained (good fitness), it can drive smoothly and efficiently to different locations (tasks) without breaking down. But if parts of the car are malfunctioning, even the best maintenance won't matter. Similarly, to live a full life and take on challenges, both health and fitness must work hand-in-hand.

A well-nourished and fit person is better able to learn and has more energy, stamina, and self-esteem. A healthy eating pattern along with regular exercise will certainly help to remain fit.

Proper nutrition is vital for physical fitness. It provides the essential nutrients needed for energy, muscle recovery, and overall health. When your body receives the right nutrients, you feel more energetic, can endure strenuous activities longer, and generally have a more positive outlook, which boosts self-esteem. For example, athletes often closely monitor their diets to ensure they consume enough vitamins and minerals to support their training.

Think of a garden. To grow beautiful flowers, it needs the right soil mix, water, and sunlight (nutrition). If it doesn't get those essentials, the flowers won't thrive. Similarly, a student's brain requires a balanced diet rich in nutrients to function at its best during studies and activities.

Teenagers between the ages of 12 and 18 who have unhealthy eating behaviours and are undernourished develop eating disorders.

During adolescence, teenagers go through rapid growth and development, which increases their nutritional needs. If they do not eat a balanced diet, they can become undernourished. This poor nutrition can lead to unhealthy eating behaviors or disorders. For instance, if a teenager skips meals or eats mostly junk food, they may not get enough vitamins and minerals necessary for growth, which can lead to disorders like anorexia or bulimia.

Consider a young plant that is not watered regularly. As it tries to grow, it might become stunted or withered. Similarly, teenagers who do not nourish their bodies properly may struggle with growth and health, potentially leading to serious eating disorders in their desire to conform to certain body images.
