Step-by-step explanation:
About 15 percent of those seeking help for chronic insomnia suffer from primary or secondary insomnia. Primary insomnia, also known as idiopathic insomnia, is sleeplessness not attributable to a medical, psychiatric, or environmental cause. On the other hand, secondary insomnia is sleep difficulty resulting from another issue such as health conditions, pain, medication use, or substance abuse.
Insomnia is the most common sleep disorder, and its treatment may involve lifestyle changes, psychological strategies like cognitive-behavioral therapy, or medication. However, treating insomnia with medication can be problematic due to the potential for dependence and alteration of the sleep cycle. Patients are generally advised to seek professional treatment, especially if the insomnia severely affects their quality of life.
