Health risks refer to factors or behaviors that can lead to illness or injury. These can include lifestyle choices like poor diet, lack of exercise, and smoking. For example, consuming too much sugar can increase the risk of diabetes, while not getting enough physical activity can lead to heart disease. Understanding these risks is essential for making healthier choices. Additionally, environmental factors can also pose health risks. Exposure to pollutants in the air or water can lead to serious health issues, such as asthma or cancer. It's important to be aware of both personal habits and environmental influences to reduce the chances of developing health problems in the future.
