Health risks refer to factors or behaviors that increase the likelihood of developing a health problem or disease. These can include lifestyle choices such as poor diet, lack of exercise, smoking, and excessive alcohol consumption. Environmental factors, like pollution and exposure to harmful substances, also contribute to health risks. Certain populations may face higher health risks due to genetics, age, or pre-existing conditions. For example, individuals with a family history of heart disease may be more susceptible to similar issues. Understanding and managing these risks can help improve overall health and prevent serious medical conditions.
