Which of the following is NOT considered a risk factor for mental illness?

Regular exercise is recognized for its positive effects on mental health, making it beneficial rather than a risk factor for mental illness. Engaging in physical activity has been shown to reduce symptoms of anxiety and depression, improve mood, and enhance overall emotional well-being. It helps in managing stress and is often recommended as part of mental health strategies.

In contrast, sleep deprivation, heavy alcohol use, and isolation are well documented as risk factors that can contribute to the development of mental health issues. Sleep deprivation can disrupt normal brain function and emotional regulation, heavy alcohol use can lead to dependency and exacerbate mental health conditions, and social isolation can lead to feelings of loneliness and despair, further increasing the risk for mental illness. Thus, regular exercise stands out as a positive factor that supports mental health rather than a risk factor.
