What is Non-24-Hour Disorder?

Non-24 is a serious, chronic circadian rhythm disorder that's very common in people who are totally blind. It causes nighttime sleep problems and a wide range of daytime difficulties, including an overwhelming urge to nap that can lead to decreased productivity, as well as complications in your social life. This website will help you understand Non-24, help you manage its impact on your life, and give you the information you need to talk about it with family, friends, and doctors.

Non-24 and your master body clock

Everyone has a master body clock. For most people, the body clock runs slightly longer than 24 hours and is reset every day by environmental light that's detected by the eye, which then signals the brain. For people who are totally blind, however, the body clock becomes out of sync with the 24-hour day-night cycle, and your body's natural rhythms can sometimes have you sleeping during the day and awake at night. Because the non-24-hour body clock creates an ever-shifting sleep-wake cycle, Non-24 is classified as a circadian rhythm disorder.

Could you have Non-24?

Non-24 makes it difficult to fall asleep or stay asleep at night and creates an uncontrollable urge to sleep during the day. This can lead to exhaustion and a decrease in overall functionality and well-being, difficulties in managing school or work, and problems with concentration. Do you have any of these symptoms?
