N24 Awareness Day

Unless you or a close friend is afflicted with Non-24-hour sleep–wake disorder (N24), you have probably never heard of this circadian rhythm disorder, which can be debilitating to those who suffer from it.

Most of those with N24 are blind, so their brains do not get the visual cues of the 24-hour day (ie. the sun). As many of half of those who have no light perception may have N24. However, there are cases of sighted people having N24. Sometimes they have sustained a brain injury, or they may have autism or another neurodivergence. The causes are not know.

A person trying to function with N24 may appear to be narcoleptic, a night owl, or just plain lazy, but they are not. The brain of a person with N24 is entrained to a different circadian rhythm than 24 hours. They are usually on a cycle that is 25 hours or longer, though cases where it is shorter than 24 hours do sometimes occur. Since this means that the person’s natural sleep phase occurs one hour later with each calendar day, their sleep phase advances around the clock, with them sometimes sleeping during the day, and sometimes during the night. Working a conventional job is difficult or impossible, and advice like “go to sleep fifteen minutes earlier each night until you’re going to bed at a reasonable hour” end up causing more problems.

While there are some treatments available that may help with N24, there is no cure.

Why would I write about something like N24 on a blog about reading and writing? I do have a tie-in! Matt, the protagonist in my book In the Tick of Time suffers from N24 following a head injury (sorry, minor spoiler!) I’ve put In the Tick of Time on sale for $0.99 for one day on Kindle and Kobo to help raise awareness for N24. Grab it today, because after that, it goes back up!
