ClassX Video Lessons Youtube Channel Learning Junction Why Do We Fall Ill? – Classification, Types and Causes of Diseases
Hello friends! Today, we’re going to explore why we sometimes get sick. Imagine you’re playing with your paper boat in the rain. It’s fun, but you need to be careful! Rainy weather can lead to stagnant water, which is a perfect home for diseases like malaria and dengue. Staying healthy is super important for everyone.
If you start sneezing and your eyes turn red, you might have to skip school for a few days. Being sick can stop you from doing your usual activities. But why do we get sick in the first place?
Diseases can be grouped into two main types: acute and chronic.
Acute diseases come on quickly and don’t last long, usually just a few days or weeks. Think of a cold or a bladder infection. They show up suddenly and then go away.
Chronic diseases develop slowly and can last for months or even years. An example is Alzheimer’s disease, where people gradually start losing their memory.
We can also classify diseases as infectious or non-infectious.
Infectious diseases are caused by tiny organisms like bacteria, viruses, fungi, and parasites. These can live in your body and make you sick under certain conditions. For example, diphtheria is a serious disease caused by bacteria.
Non-infectious diseases aren’t caused by germs. They often result from genetics, poor nutrition, the environment, or lifestyle choices. For instance, obesity can happen if someone eats too much and doesn’t exercise enough.
There are several reasons why we might fall ill:
Leading a healthy lifestyle can help prevent many illnesses. Regular exercise, eating a balanced diet, and getting enough sleep are great ways to stay healthy.
Now you know a lot about why we fall ill! Keep learning and take care of yourself. Bye!
Keep a diary for a week where you note down any symptoms you or your family members experience, like sneezing or coughing. Try to identify if they are signs of acute or chronic diseases. This will help you understand how often these symptoms occur and how they affect daily life.
Create a colorful poster that shows different ways to stay healthy, such as exercising, eating a balanced diet, and getting enough sleep. Display your poster in the classroom to remind everyone of the importance of a healthy lifestyle.
Pair up with a classmate and take turns being a doctor and a patient. The “patient” describes symptoms, and the “doctor” suggests whether it might be an infectious or non-infectious disease and gives advice on how to get better. This activity will help you learn how to communicate about health issues.
Choose a disease to research, such as malaria or obesity. Prepare a short presentation for the class, explaining whether it is acute or chronic, infectious or non-infectious, and how it can be prevented or treated. This will help you learn more about specific diseases.
With the help of a teacher, conduct an experiment to see how germs spread. Use glitter or colored powder to represent germs and see how they transfer from one person to another through touch. This will show you the importance of personal hygiene in preventing diseases.
Sure! Here’s a sanitized version of the transcript:

Hello friends! Today we’ll learn about why we fall ill.
You’re playing with your paper boat in the rain; you should be careful! Diseases and infections are commonly linked with this season, as stagnant rainwater provides a breeding ground for various conditions like malaria and dengue. Health is one of the most crucial aspects of everyone’s life.
If you’re sneezing and your eyes look red, you might not be able to go to school for a few days. Not being fit or healthy can prevent you from carrying out normal day-to-day activities.
Diseases can be categorized into two types: acute diseases and chronic diseases. Acute diseases generally develop suddenly and last a short time, often only a few days or weeks. For example, most colds and bladder infections fall into this category. Chronic diseases develop slowly and may worsen over an extended period, such as months or even years. An example is Alzheimer’s disease, where people start losing their memory gradually.
It’s important to eat healthily and take proper care of your health. There is also another way to categorize diseases: infectious and non-infectious diseases. Infectious diseases are caused by bacteria, viruses, fungi, and parasites. These organisms can live in the body and, under certain conditions, may cause disease. For example, diphtheria is a serious infection caused by bacteria. Non-infectious diseases are not caused by infectious agents but usually arise from genetics, malnutrition, environment, and lifestyle. For instance, obesity is often caused by overeating and lack of physical activity.
So, why do you fall ill? There are various reasons, and I will explain a few of them here:
1. **Bad Surroundings**: You can fall ill if you live in an environment with polluted air, water, or harmful insects. For example, contaminated water may cause diarrhea.
2. **Lack of Personal Hygiene**: Neglecting personal hygiene can lead to numerous diseases. For example, not brushing your teeth can lead to decay.
3. **Poor Sleep**: The body uses sleep to recover and prepare for the next day. Sleep deprivation can lead to many problems, including heart disease.
4. **Economic Condition**: If a person is not financially stable, they may struggle to take care of themselves, leading to various diseases. Malnutrition is a serious condition that can occur when a diet lacks the right nutrients.
5. **Mental Health**: Mental health significantly impacts physical health. For example, clinical depression may lead to weight loss or loss of appetite.
Leading a healthy lifestyle can help prevent many factors that cause illness. Regular exercise, eating a balanced diet, and prioritizing sleep are some effective ways to help prevent various illnesses.
Now you know a lot about the topic! Stay tuned for more videos. Bye!
