Personal, School and Community Health


Health is a multifaceted concept that encompasses not only physical well-being, but also mental and social health. A person is considered healthy when they are free from any physical, social, or mental issues that can impede their ability to function in daily life. It is essential to recognize that health is not simply the absence of disease or infirmity, but rather a state of complete physical, mental, and social well-being.

Physical health is often the first aspect that comes to mind when discussing health. This refers to the proper functioning of the body and the absence of any physical ailments. However, mental health is equally crucial and refers to a person’s emotional and psychological well-being. A person with good mental health is able to manage their thoughts, emotions, and behaviors, and has a positive outlook on life. Social health refers to a person’s ability to interact and maintain relationships with others in a fulfilling and respectful manner.

The importance of maintaining good health cannot be overstated. A healthy individual is better equipped to handle the challenges and stresses of daily life. Moreover, good health contributes to overall happiness and well-being. To maintain good health, it is essential to pay attention to the determinants of health. These are factors that influence a person’s health status and include genetics, environment, lifestyle, age, and nutrition.

Genetics plays a role in a person’s susceptibility to certain illnesses and diseases. Environment refers to the physical, social, and economic conditions in which a person lives, works, and plays. Lifestyle factors, such as diet, exercise, and substance use, can also significantly impact a person’s health. Age is another determinant of health, as older adults are more likely to experience health complications than younger individuals. Finally, nutrition is a crucial determinant of health, as a balanced and healthy diet is essential for maintaining good health.

Aspect Of Health

Health can be described as a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. There are various aspects of health, and they include:

  1. Physical Health: Physical health refers to the overall condition of the body, which includes the ability to perform daily tasks, maintain a healthy weight, and engage in physical activities without fatigue or pain.
  2. Mental Health: Mental health refers to the state of an individual’s emotional, psychological, and social well-being. It encompasses the ability to manage stress, anxiety, and depression, cope with life’s challenges, and maintain healthy relationships.
  3. Emotional Health: Emotional health refers to an individual’s ability to express and manage their emotions effectively. It involves the ability to recognize, express, and regulate one’s own feelings while also understanding and empathizing with others’ emotions.
  4. Social Health: Social health refers to the ability to form and maintain healthy relationships with others. It includes effective communication, social support, and the ability to connect with others on a personal level.
  5. Spiritual Health: Spiritual health refers to an individual’s sense of meaning, purpose, and connection to a higher power or belief system. It involves cultivating a sense of inner peace, mindfulness, and personal fulfillment.
  6. Environmental Health: Environmental health refers to the impact of the environment on an individual’s physical, mental, and emotional well-being. It encompasses factors such as air and water quality, access to green spaces, and exposure to toxins and pollutants.

Determinants of Health

Health is a complex and multifaceted concept that cannot be understood in isolation. It is influenced by a range of factors that are both internal and external to the individual, and these factors interact with each other in complex ways. The determinants of health are the underlying factors that shape the health of individuals and communities. These determinants can be broadly categorized as social, economic, and environmental factors, which all play a critical role in determining health outcomes.

Social factors such as education, social status, and social support networks have a significant impact on health. Education, for example, provides individuals with the knowledge and skills necessary to make informed decisions about their health, while social support networks provide a sense of belonging and emotional support that can help individuals cope with stress and adversity. Social status, on the other hand, can influence an individual’s access to resources and opportunities, which in turn can impact their health outcomes.

Economic factors, including income, employment status, and access to healthcare, are also important determinants of health. Individuals with higher incomes and better access to healthcare are more likely to live longer, healthier lives, while those living in poverty or with limited access to healthcare may experience higher rates of illness and premature death.

Environmental factors such as air and water quality, housing conditions, and access to healthy food also play a critical role in determining health outcomes. Poor environmental conditions can lead to increased rates of respiratory and other illnesses, while access to healthy food can promote good nutrition and reduce the risk of chronic diseases such as diabetes and heart disease.

It is important to note that the determinants of health are interrelated and can influence each other in complex ways. For example, poverty can lead to poor nutrition, which can in turn lead to chronic illness, creating a cycle of poor health outcomes. Similarly, lack of access to healthcare can lead to delayed diagnosis and treatment, resulting in poorer health outcomes.

Understanding the determinants of health is critical to improving health outcomes and reducing health disparities. By addressing the underlying factors that contribute to poor health, such as poverty and limited access to healthcare, we can work towards creating healthier communities and promoting greater equity in health outcomes. Some of the important determinants of health are discussed below.


Heredity refers to the process through which traits and genetic information are passed down from parents to their offspring. This process determines the physical and mental traits of every individual to some extent, and this genetic makeup is unique and cannot be altered after conception.

Genes can be either dominant or recessive, and their expression can influence an individual’s physical appearance and health. Dominant genes are visible traits that are passed on from one generation to the next, while recessive genes may not be visibly expressed unless both parents carry the recessive trait.

Unfortunately, heredity can also play a role in the development of certain genetic disorders and diseases. Examples of such disorders include chromosomal anomalies, sickle cell anemia, hemophilia, errors of metabolism, mental retardation, and some types of diabetes.

The transfer of genes from parents to their offspring can have both positive and negative effects on health. If a child inherits a gene for a genetic disorder or disease, they may experience negative health effects. On the other hand, if a child inherits healthy genes from their parents, they may enjoy good health and experience fewer health issues.

It’s important to note that genetics are only one factor in determining an individual’s overall health. Environmental factors, lifestyle choices, and medical care also play significant roles in determining an individual’s health outcomes.


The term environment is derived from the French word “Environ,” which means “surroundings.” In the context of human beings, the environment refers to the surrounding biotic and abiotic factors that man interacts with and affects. These biotic factors include plants, animals, and microorganisms, while abiotic factors include air, water, soil, and light.

The environment is a complex of many variables that surround man and other living organisms. It includes the interrelationships between water, air, plants, animals, and the interactions between man and other living creatures. These relationships can have a positive or negative effect on human health. For example, if a person breathes in contaminated air, it can lead to respiratory problems like asthma, which can have severe consequences for their overall well-being.

The environment is an inseparable system, consisting of physical, chemical, biological, social, and cultural elements that are interlinked both individually and collectively. The physical and chemical components of the environment are the non-living aspects that affect living organisms. The biological component includes all living organisms, from plants to animals to microorganisms, that interact with each other and the physical environment.

The social and cultural components of the environment refer to human interactions with the environment, including the values, beliefs, and practices that shape human behaviour towards the environment. The way in which humans interact with the environment can have a profound effect on the health of the ecosystem and, in turn, on human health.

Characteristics of a Good Environment

A good environment can be defined as one that is conducive to the well-being, growth, and flourishing of living beings. Some characteristics of a good environment include:

  1. Cleanliness: A clean environment is free from dirt, dust, pollutants, and other harmful substances. It promotes good health and reduces the risk of illnesses.
  2. Safety: A good environment is one that is safe for living beings. It should be free from hazards such as sharp objects, toxic chemicals, and dangerous animals.
  3. Comfort: A good environment should be comfortable for living beings. It should provide adequate shelter, clean water, food, and other basic needs.
  4. Natural beauty: A good environment is aesthetically pleasing and has natural beauty. This can include things such as trees, plants, flowers, and bodies of water.
  5. Diversity: A good environment is diverse and has a variety of living organisms. This promotes biodiversity and ensures a healthy ecosystem.
  6. Sustainability: A good environment is sustainable and does not deplete its resources faster than they can be replenished. It should also minimize waste and pollution.
  7. Access: A good environment should be accessible to all living beings, regardless of their race, gender, or socio-economic status.

How to Maintain a Good Environment

Maintaining a good environment requires effort and commitment from individuals and communities. Here are some tips to help you maintain a good environment:

  1. Reduce, reuse, and recycle: This is the most basic way to maintain a good environment. By reducing waste, reusing items, and recycling materials, you can reduce the amount of trash that ends up in landfills, polluting the environment.
  2. Conserve water: Water is a precious resource, and we must use it wisely. Fixing leaks, taking shorter showers, and turning off the faucet while brushing your teeth are just a few ways to conserve water.
  3. Use eco-friendly products: Choose products that are biodegradable, environmentally friendly, and safe for humans and animals. Avoid using products that contain harmful chemicals or that contribute to pollution.
  4. Plant trees and plants: Trees and plants absorb carbon dioxide and produce oxygen, making them essential for a healthy environment. Planting trees and plants in your yard or community can help reduce pollution and provide habitat for wildlife.
  5. Reduce energy consumption: Use energy-efficient appliances, turn off lights and electronics when not in use, and use public transportation, carpooling, or cycling to reduce your carbon footprint.
  6. Support local environmental organizations: Supporting local environmental organizations is a great way to get involved in the community and make a difference in the environment. You can volunteer your time, donate money, or participate in community events.


The term “lifestyle” refers to the way in which individuals live, encompassing a wide range of social values, attitudes, and activities. It encompasses both cultural and behavioral patterns, as well as lifelong personal habits that have been developed through the process of socialization. For example, habits such as smoking and alcoholism are often shaped by an individual’s social interactions with parents, peer groups, friends, siblings, and through exposure to various forms of media.

When it comes to health, the promotion of healthy lifestyles is crucial. This can involve taking steps such as maintaining adequate nutrition, getting enough sleep, and engaging in regular physical activity. Health is both a consequence of an individual’s lifestyle choices and a factor that can determine future lifestyle choices. Unfortunately, many modern-day health problems in developed countries, such as coronary heart disease, obesity, lung cancer, and drug addiction, are often linked to unhealthy lifestyle choices.

On the other hand, in developing countries such as Nigeria, where traditional lifestyles persist, the risks of illness and death are often associated with a lack of sanitation, poor nutrition, inadequate personal hygiene, and limited access to basic human necessities. In these settings, customs and cultural patterns can also impact overall health outcomes.

Ultimately, achieving optimal health requires the adoption of healthy lifestyles. As students, it is important to cultivate habits and make choices that will improve our health, such as participating in physical activities, getting adequate rest and recreation, receiving regular medical check-ups, and consuming fruits and vegetables. At the same time, it is important to avoid engaging in lifestyle habits that are detrimental to our health, such as smoking, excessive alcohol intake, promiscuity, violence, and theft.
