Setting boundaries can significantly improve work-life balance and health by preventing burnout and enhancing overall well-being. By clearly communicating availability and prioritizing personal time, individuals can reduce work-related stress and increase time for self-care, family, and hobbies. Establishing limits on work hours and using techniques like time management can foster productivity while ensuring personal time is respected. This balance not only enhances mental health but also encourages physical activities, leading to improved fitness and overall quality of life.
