Many studies investigate the intricacies of obsessive-compulsive disorder (OCD), and today what causes, triggers, and helps this mental health condition is better understood than it was in the past. OCD is an anxiety disorder characterized by unreasonable thoughts and fears (obsessions) that lead a person to do repetitive behaviors (compulsions).
Washing the hands after leaving the bathroom and before eating are sensible hygiene precautions that everyone should take. However, people with OCD tend to wash their hands far more often than the average, eventually irritating skin and possibly causing infection. People with OCD may compulsively or repeatedly clean their homes, as well. Excessive cleanliness is the compulsion caused by a specific fear (obsession), such as a fear of germs.
