The stages of sleep are divided into non-REM (rapid eye movement) and REM sleep. Non-REM sleep is further divided into three stages: N1, N2, and N3. N1 is the stage between wakefulness and sleep, N2 is a light sleep stage, and N3 is a deep sleep stage.

During REM sleep, our brains are active and dreaming occurs. This stage is important for cognitive function and memory consolidation.

As we age, our sleep patterns change. Infants and young children have more REM sleep, which is important for brain development. As we reach adulthood, the amount of REM sleep decreases. Older adults may experience more fragmented sleep and spend less time in deep sleep stages.

Overall, as we age, we tend to have more difficulty falling asleep and staying asleep, and our sleep becomes lighter and more easily disrupted. This can lead to increased daytime sleepiness and fatigue. It's important to prioritize good sleep habits and seek medical advice if sleep disturbances become a problem.

Healthy People 2020 identifies several targets for intervention aimed at reeducating the risk of unintentional injury and violence. These targets include promoting safe and supportive environments, increasing the use of safety equipment, reducing exposure to environmental hazards, and promoting violence prevention and response strategies.

Promoting safe and supportive environments involves creating and maintaining physical and social environments that are safe and conducive to healthy behaviors. This can include implementing policies and programs to reduce the risk of injury and violence in homes, schools, workplaces, and communities.

Increasing the use of safety equipment is another target for intervention, which involves promoting the use of protective gear and devices to prevent injuries. This can include initiatives to increase the use of seat belts, helmets, and other safety equipment in various settings.

Reducing exposure to environmental hazards is also a key target, which involves identifying and addressing environmental factors that contribute to unintentional injuries and violence. This can include efforts to reduce exposure to pollutants, toxins, and other environmental hazards that pose a risk to health and safety.

Finally, promoting violence prevention and response strategies is an important target for intervention, which involves implementing programs and policies to prevent and respond to violence in various settings. This can include promoting conflict resolution skills, providing support services for victims of violence, and implementing policies to address the root causes of violence.

Overall, these targets for intervention aim to reeducate the risk of unintentional injury and violence by addressing the underlying factors that contribute to these issues and promoting strategies to prevent and respond to them effectively.

The biopsychosocial model suggests that health and well-being are influenced by a combination of biological, psychological, and social factors. When it comes to unintentional injury being the leading cause of death for adolescents and young adults, this model can help us understand why this is the case.

Biologically, adolescents and young adults are at a stage of development where they may engage in risky behaviors due to their still-developing brains and decision-making abilities. This can lead to increased likelihood of engaging in activities that put them at risk for unintentional injury, such as reckless driving or substance abuse.

Psychologically, this age group may also be more prone to impulsivity and sensation-seeking behaviors, which can lead to engaging in risky activities without fully considering the potential consequences. Additionally, mental health issues such as depression or anxiety can also contribute to risk-taking behaviors and increase the likelihood of unintentional injury.

Socially, adolescents and young adults may be influenced by peer pressure and social norms that encourage risky behaviors. They may also have limited experience and knowledge about safety measures and risk prevention, leading to a higher likelihood of unintentional injury.

Overall, the biopsychosocial model helps us understand that a combination of biological, psychological, and social factors contribute to unintentional injury being the leading cause of death for adolescents and young adults. By addressing these factors through education, support, and intervention, we can work towards reducing the incidence of unintentional injury in this age group.
