This chapter reveals the important perspectives on mental health, mental illness, and technology utilization; mental health education and mental health nursing; the overview of Cognitive Behavioral Therapy (CBT); CBT, depression, anxiety, and insomnia; CBT and Obsessive-Compulsive Disorder (OCD); and CBT and heart failure. Mental health strengthens the individuals' ability to have healthy relationships; make good life choices; maintain physical health and well-being; handle the natural ups and downs of life; and grow toward individuals' potential. Mental health is associated with higher productivity, better performance, more consistent work attendance, and fewer workplace accidents. CBT is a goal-oriented psychotherapy treatment that takes a practical approach to problem-solving skills. CBT involves recognizing the unhelpful or destructive patterns of thinking and reacting, thus modifying or replacing these patterns with more realistic or helpful ones.
