Involvement of some individuals in risky behaviours such as unprotected sex, smoking and drug abuse is quite common. This has given rise to concepts such as ‘risk society’, ‘risk and identity’ and ‘risk management’. There are two forms of risk – external and internal. It is important to understand the concept of risk-taking and risk management, especially by the health professionals, because it facilitates the understanding of patients’ involvement in risk-taking behaviours and could also be helpful when health professionals formulate health policies. This paper discusses a number of reasons why some people engage in risky behaviours, sociological view on risk management as well as some occupational risks, with emphasis on internal risks.
