Non-24-Hour Sleep-Wake Disorder is a rare circadian rhythm sleep disorder that affects the timing of an individual's sleep-wake cycle. Unlike most people who have a 24-hour sleep-wake cycle, individuals with Non-24 experience a cycle that is longer than 24 hours, causing their sleep patterns to gradually shift over time.
This disorder primarily affects individuals who are totally blind, as their lack of light perception disrupts the synchronization of their internal body clock with the external environment. The symptoms of Non-24 include difficulty falling asleep, excessive daytime sleepiness, and irregular sleep patterns.
Managing Non-24 can be challenging, but there are strategies that can help individuals cope with the disorder. Maintaining a consistent sleep schedule, maximizing exposure to natural light during the day, and using melatonin supplements under medical supervision are some of the treatment options available.
If you or someone you know is experiencing irregular sleep patterns and suspect Non-24, it is important to consult a healthcare professional for an accurate diagnosis and appropriate management strategies.
