Lifestyle-related chronic diseases are a major cause of death and disability. Globally, lifestyle behaviours continue to changed dramatically as eople are spending more time at work and less time taking care of themselves. The lack of sleep and physical activity, as well as the consumption of unhealthy food can lead to chronic diseases such as diabetes or heart disease. There are many risk factors for lifestyle-related chronic diseases, including diet, physical activity, alcohol consumption and tobacco use. These factors can be influenced by the environment and social influences. The risk of developing these conditions increases with age and is also higher in people who have a family history of these diseases. Certain lifestyle factors can increase the risk for chronic disease even more. These include smoking cigarettes, being overweight or obese, not getting enough physical activity or sleep, and being exposed to secondhand smoke. Some of the most common lifestyle-related chronic diseases include cardiovascular disease, type 2 diabetes mellitus, obesity, cancer and asthma. Some of these factors include:

– Diet: A diet high in calories and low in nutrients can increase the risk of chronic diseases as the quality of a diet is determined by the balance between calories and nutrients. A diet high in calories but low in nutrients can increase the risk of chronic diseases, particularly among those who are overweight or obese. This is because a higher calorie intake coupled with a lower nutrient intake leads to weight gain, which may lead to insulin resistance, diabetes, heart disease, and other health problems.

– Activity level: Physical activity is one of the most important aspects of maintaining a healthy lifestyle. It helps to reduce the risk of chronic diseases and improve overall health. There are many benefits that come with being physically active: it can help prevent obesity, improve your mood and mental health, and increase energy levels. Physical activity has also been linked to reduced risk of heart disease, type 2 diabetes mellitus (T2DM) and some types of cancer.

– Alcohol consumption: Alcohol use is a major risk factor for the global burden of disease. The level at which chronic diseases start to increase in risk with alcohol use is low – there is no level of alcohol intake that can be considered safe.

– Tobacco use: tobacco kills nearly six million people each year, of which more than 600 000 are non-smokers dying from breathing second-hand smoke.

– Sleep duration and quality: Sleep deprivation can lead to several chronic diseases and conditions like heart attack, stroke, and high blood pressure. Poor sleep may also increase the chances of developing dementia later in life by as much as 65%.
