Risky behaviour refers to actions or activities that expose individuals or others to the possibility of physical, mental, emotional harm, or abuse. These behaviours increase the likelihood of negative outcomes such as injury, disease, legal consequences, or social problems

. Common examples of risky behaviour include:

• Substance abuse (drugs, alcohol, tobacco)
• Criminal or anti-social activities (stealing, vandalism, fighting)
• Risky sexual behaviours (unprotected sex, sexting)
• Carrying or using weapons like knives
• Dangerous driving (speeding, driving under the influence)
• Truancy and other forms of rule-breaking

Risky behaviours are often seen in young people, who may engage in them due to thrill-seeking, peer pressure, desire for social acceptance, or lack of emotional maturity and impulse control. Teenagers may not fully understand the risks or consequences of their actions because their brains are still developing, particularly the areas responsible for planning and impulse control

. While taking some risks is a natural part of growing up and can contribute to independence and identity formation, risky behaviours become problematic when they lead to harm or prevent individuals from reaching their potential

. In summary, risky behaviour is any conduct that potentially exposes a person or others to harm or significant risk of harm, often involving choices that can have adverse physical, legal, or social consequences
