Non-communicable diseases are health conditions that can't be passed from... Show more
Non-communicable diseases are conditions you can't catch from other people - they develop within your body over time. Think of them as health problems that build up rather than spread around.
The main types include cancer (when cells grow uncontrollably), diabetes (problems with blood sugar control), cardiovascular diseases (heart and blood vessel problems), and chronic respiratory diseases like asthma .
These diseases are incredibly common and affect millions of people worldwide. The good news? Many of them can be prevented or managed with the right knowledge and lifestyle choices.
Key Point: Unlike communicable diseases , you can't catch these from someone else - they develop due to various factors over time.
A risk factor is basically anything that increases your chances of developing a disease or infection. It's like a warning sign that suggests you might be more likely to get ill, but it doesn't guarantee you will.
Think of risk factors as pieces of a puzzle - having one doesn't mean you'll definitely get sick, but having several increases your odds. Some people with multiple risk factors stay healthy, while others with fewer risk factors might still develop diseases.
This concept is essential for understanding how diseases develop and, more importantly, how we might prevent them by reducing our personal risk factors where possible.
Remember: Having a risk factor doesn't mean you'll definitely get a disease - it just means your chances are higher than someone without that risk factor.
Several different types of factors can affect your risk of developing non-communicable diseases. Lifestyle factors are the ones you have most control over - things like your diet, how much you exercise, whether you smoke, and how much alcohol you consume.
Environmental factors are harder to control but still important. These include exposure to air pollution, chemicals, or radiation in your surroundings. Where you live and work can significantly impact your health over time.
Genetics play a role too - some people inherit genes that make them more susceptible to certain diseases like cancer or heart disease. While you can't change your genes, knowing your family history helps you make better lifestyle choices.
Top Tip: Focus on what you can control! While you can't change your genetics or completely avoid environmental risks, you have significant power over your lifestyle choices.
Here's a crucial concept that trips up many people: "correlation does not mean causation." This means that just because two things happen together doesn't mean one causes the other.
For example, if researchers find that people who eat more ice cream have higher rates of drowning, it doesn't mean ice cream causes drowning. Both increase in summer - that's the real connection.
In health research, this is vital. A risk factor might be correlated with a disease without directly causing it. Other hidden factors might be involved, or several factors might work together to increase disease risk.
Think Critically: Always question whether a relationship between two things is actually cause-and-effect, or whether other factors might explain the connection.
Exercise is one of the most powerful tools for reducing your risk of non-communicable diseases. Regular physical activity strengthens your heart, improves blood circulation, and helps maintain healthy blood pressure.
Exercise also helps control weight, reduces inflammation in your body, and improves how your body processes sugar - all of which lower your risk of diabetes and cardiovascular disease. It even supports your immune system and mental health.
The brilliant thing about exercise is that you don't need to become a professional athlete to see benefits. Even moderate activity like brisk walking, cycling, or playing sports a few times a week can significantly reduce your disease risk.
Get Moving: Aim for at least 150 minutes of moderate exercise per week - that's just over 20 minutes a day to significantly improve your long-term health!

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7.
