Attention deficiency hyperactive disorder (ADHD) is a neuropsychiatric disability characterized by attention problems, impulsivity, and hyperactivity that can affect education, working life, social relationships, and physical and mental health. Research shows a shortened life expectancy in adults with ADHD which has to do with impaired lifestyle habits. In the field of health sciences, it is important to alleviate suffering, promote health, and prevent ill health. The purpose of this chapter is to describe factors that affect the health and lifestyle of adults with ADHD. The method is a literature search. Adults with ADHD were affected by cognitive impairments that affected life to a large extent. Lifestyle habits with a sedentary lifestyle, poor diet, and drug use were more common in people with ADHD. In addition, comorbidity with both physical and mental health is common. Loneliness and deteriorating quality of life plague many people with ADHD. Combined treatment methods with psychosocial interventions are important. Health-promoting lifestyle programs where support for physical, mental, and social health is important. Conclusion: Research on lifestyle programs for adults with ADHD is lacking. There is some research that supports the idea that continuous health-promoting lifestyle programs based on interpersonal relationships, health education, and health discussions as well as cognitive support can be useful for lifestyle changes among people with ADHD.
