Heart disease, stroke, cancer, diabetes and chronic respiratory diseases remain among the major health challenges affecting populations around the world.
The World Health Organisation (WHO) says many non-communicable diseases are associated with risk factors that can be prevented or reduced. These include tobacco use, physical inactivity, unhealthy diets and harmful alcohol consumption.
While no individual can completely eliminate the possibility of developing a serious illness, adopting healthier habits can significantly reduce certain risks and support better physical and mental well-being.
Here are 10 practical measures that can help protect against life-threatening diseases:
1. Eat a healthy, balanced diet
A nutritious diet is one of the foundations of good health. WHO recommends eating a variety of foods, including fruits, vegetables, legumes and whole grains.
People should also limit excessive intake of salt, free sugars and unhealthy fats. Making healthier food choices can help reduce the risk of conditions such as heart disease, diabetes and some cancers.
Rather than relying heavily on highly processed foods, individuals can aim for a balanced diet containing a variety of nutrient-rich foods in appropriate portions.
2. Stay physically active
Regular physical activity benefits both the body and mind. It can help reduce the risk of cardiovascular disease, diabetes and some forms of cancer while supporting healthy weight management.
WHO recommends that adults undertake at least 150 minutes of moderate-intensity physical activity each week, or an equivalent amount of vigorous activity.
Exercise does not necessarily have to involve strenuous workouts. Activities such as brisk walking, cycling, swimming or other forms of regular movement can contribute to meeting physical activity goals.
3. Avoid tobacco
Tobacco use is one of the leading preventable causes of disease and death.
Smoking and other forms of tobacco use are associated with serious illnesses, including cancer, heart disease, stroke and chronic respiratory diseases.
People who do not use tobacco should avoid starting, while smokers and other tobacco users can seek professional support to quit. Stopping tobacco use can substantially reduce health risks over time.
4. Avoid harmful alcohol use
Excessive alcohol consumption can contribute to a range of serious health problems and can affect both physical and mental well-being.
WHO identifies harmful alcohol use as an important risk factor for non-communicable diseases.
Reducing alcohol consumption—or avoiding alcohol altogether—can therefore be an important part of protecting long-term health.
5. Maintain a healthy weight
Excessive weight gain and obesity can increase the risk of several serious conditions, including cardiovascular disease and type 2 diabetes.
Maintaining a healthy weight is best approached through sustainable habits rather than extreme diets. Eating a balanced diet, staying physically active and making healthier lifestyle choices can help support healthy weight management.
6. Go for regular health checks
Some potentially serious diseases can develop without obvious symptoms, particularly in their early stages.
Regular medical checks and appropriate screening can help detect certain conditions earlier, when treatment or management may be more effective.
People should discuss appropriate health checks with qualified healthcare professionals, particularly if they have risk factors, a family history of certain diseases or concerns about their health.
7. Maintain good hygiene
Good personal and environmental hygiene remains an important defence against infectious diseases.
Regular handwashing, safe food preparation, access to clean drinking water and maintaining a clean environment can reduce exposure to disease-causing organisms.
Simple hygiene practices can protect not only individuals but also people around them, particularly those who may be more vulnerable to infections.
8. Keep recommended vaccinations up to date
Vaccination is an important public health tool for preventing infectious diseases that can cause serious illness.
Individuals should keep up to date with vaccines recommended for them by qualified healthcare professionals and relevant public health authorities.
Vaccination can provide protection against a range of infections and also contribute to broader community protection.
9. Manage stress and get enough rest
Good health involves more than physical fitness and nutrition. Mental well-being, adequate sleep and healthy social connections are also important.
Managing stress, getting sufficient rest, remaining physically active and maintaining supportive relationships can contribute to overall well-being.
Developing healthy routines can also make it easier for people to maintain other positive behaviours, including regular exercise and balanced eating.
10. Seek medical attention when necessary
Unusual or persistent symptoms should not be ignored.
Seeking medical advice when necessary can help ensure that health problems are properly assessed, diagnosed and treated. Early professional attention may be particularly important when symptoms are severe, persistent or worsening.
People should also avoid relying on self-medication when a condition requires professional evaluation.
Prevention starts with everyday choices
Reducing the risk of serious disease is not about achieving perfect health or eliminating every possible risk. It is about making practical choices that support long-term well-being.
Eating nutritious food, staying active, avoiding tobacco, limiting harmful alcohol use, maintaining a healthy weight and attending appropriate health checks can all contribute to a healthier life.
Combined with vaccination, good hygiene, adequate rest and timely medical care, these measures can help individuals reduce preventable risks and take greater control of their long-term health.
