Insomnia is a very difficult thing to deal with. Unlike most of the other conventional diseases, the effects of insomnia spill over from a simple health disorder to directly affect several other parts of your life. In general, insomnia can be classified into 2 types based on what the effects of it can be.
Primary insomnia refers to just facing sleeping problems and deals with several disorders. Secondary insomnia, on the other hand, not only has all the effects of the primary one, but is related to other health problems like asthma, arthritis, cancer medication etc.
