I have delayed sleep phase disorder, what should i do?

Delayed Sleep Phase: Discuss with your medical provider/ sleep specialist. Potential treatment options include melatonin, light therapy, better sleep hygiene ; chronotherapy.

Teenage sleep: This is commonly found in teenagers. It occurs when a person stays up later and later and sleeps later and later. Thus shifting their sleep wake cycle so that they sleep more in the day and stay up more at night, it can be treated with chronotherapy - walking the person around the clock to the correct times.
