You climb into bed, turn off the light, and close your eyes, but you can't fall asleep. For most of us, it's just one annoying night, but for people with fatal familial insomnia, or FFI, it's the beginning of the end. An extremely rare genetic disease passed down through generations, FFI's primary symptom is sleeplessness, but with a fatal twist: victims are dead within months. To understand FFI, National Geographic delves into the science of sleep-the most elusive biological function we have-to find out why we need sleep and what happens to us when we don't get it. Witness the pioneering research inside the sleeping brain as well as the mind forbidden to rest for days at a time.

How to Watch National Geographic Fatal Insomnia Legally and Safely

If you want to stream National Geographic Fatal Insomnia through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry National Geographic Fatal Insomnia films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
