[Insomnia and lifestyle-related diseases].

As both insomnia and lifestyle-related diseases are associated with a variety of underlying factors, they have been considered to occur as a complication of each other. Moreover, evidence has been presented in recent studies that they are closely related to each other as risks of development and exacerbation. As unhealthy lifestyle-habits have long been recognized to increase the risks of lifestyle-related diseases and their worsening, it is natural that sleep, which takes up one third of a person's life, is markedly associated with disorders such as hypertension and diabetes. It is important to provide interventions for insomnia and other sleep disorders based on the same viewpoint as for lifestyle-related diseases, and understand that lifestyle advice, including sleep hygiene, and drug treatment with sleeping pills are also effective for the treatment of lifestyle-related diseases themselves.
