The main lifestyle factors that affect health are: diet, exercise, sleep, stress, and avoiding harmful substances (tobacco, alcohol, drugs). Each of these is something you can control.
Check: What are the five main lifestyle factors that affect your health?
A risk factor is something that increases your chance of developing a disease. Poor diet, lack of exercise, smoking, and alcohol are risk factors for heart disease, obesity, and diabetes. Not all risk factors are lifestyle choices - age and genetics are also risk factors.
Check: What is the difference between lifestyle risk factors and non-lifestyle risk factors?
Risk factors work together. Someone who eats poorly AND doesn't exercise has a higher risk than someone with just one of these factors. The good news is that healthy choices also combine - eating well AND exercising is even better than doing just one.
Check: Why is making several healthy choices better than just one?
Every day you make lifestyle choices - what to eat, whether to be active, how much sleep to get. Understanding how these affect your circulatory system and overall health helps you make informed decisions for a healthy life.
Check: Give an example of a daily decision that affects your long-term health.
Lifestyle choices are the daily decisions we make about how we live - what we eat, how active we are, how much we sleep, and whether we avoid harmful substances. These choices have a huge impact on our long-term health, especially our circulatory system.
A risk factor is anything that increases your chance of developing a disease. Risk factors can be:
The more risk factors you have, the higher your chance of developing conditions like heart disease, Type 2 diabetes, and obesity.
Your daily choices directly impact your heart and blood vessels:
Many serious diseases are preventable through healthy lifestyle choices. The choices you make now - as a child - help establish habits that will affect your health for life. In the UK, cardiovascular disease is one of the biggest causes of death, yet many cases could be prevented through better lifestyle choices.
The NHS runs the Change4Life campaign to help families make healthier choices. It encourages "5 a day" fruit and vegetables, "60 active minutes" daily, and swapping sugary drinks for water. Research shows that children who follow these guidelines have healthier hearts and lower risk of obesity.
Many UK primary schools participate in "The Daily Mile" where children run or jog for 15 minutes every day. Studies show this simple change improves fitness, helps maintain healthy weight, and increases concentration in class. It started in Scotland in 2012 and has spread to over 15,000 schools worldwide.
In 2018, the UK introduced a sugar tax on soft drinks. Companies reduced sugar in their recipes by an average of 44%. This shows how policies can support healthy choices - making the unhealthy option more expensive encourages healthier alternatives.
Research by UK scientists found that children who get enough sleep (9-12 hours) perform better in school and have stronger immune systems. Some schools have moved start times later based on this evidence. Sleep is a lifestyle choice that affects both physical health and learning.

A risk factor increases the chance of disease - it doesn't guarantee it. Someone who smokes might not get lung cancer, but their risk is much higher. Equally, someone with no risk factors could still become ill. It's about probability, not certainty.
Remember: lifestyle risk factors are things you can control (diet, exercise, smoking). Non-lifestyle risk factors are things you cannot control (age, genetics, family history). Questions often ask you to distinguish between these.
When asked about healthy lifestyle, don't just mention diet or exercise alone. A healthy lifestyle involves multiple factors: balanced diet, regular exercise, enough sleep, avoiding harmful substances, and managing stress. Include several in your answers.
Risk factors work together. Someone with poor diet AND lack of exercise has higher risk than someone with just one of these. Similarly, making multiple healthy choices provides greater protection than just one change.
