There are sleep studies and certain therapies for sleep. A sleep study can cost a lot of money but can be covered by insurance, making the cost to the patient much, much more affordable. Behavioral therapies, such as talk therapy, can be complementary to the sleep treatments sleep clinics provide. If you need one of these therapies, a clinic may be able to refer you for it. Sleep studies and therapies can be invaluable in helping a patient understand the factors involved in their sleep and how to address them better.
