00:00Have you ever been so close to dosing off, your eyes almost closed, and then suddenly
00:04your whole body chores like you are about to fall off a cliff.
00:07It feels incredibly real, like gravity is pulling you down, but then you are awake.
00:12If you have ever been curious about why this happens, today we are going to explain it
00:23in a simple way.
00:23First, take a deep breath, you are not alone, and you are not definitely strange.
00:28Most people, about 60-70% have felt this whole falling sensation just before they sleep.
00:33It even has a scientific name, happening jerk, sometimes referred to as a sleep start.
00:38It is an involuntary muscle twitch that occurs right as you are dripping off.
00:41It might sound frightening, but it is actually completely normal and harmless.
00:45Let's visualize what's going on inside your body.
00:48When you fall asleep, your brain and body don't start, turn off like a light switch.
00:52Instead they go through different stages, your brain feels slow down, your muscles relax,
00:56your heart decreases, and your breathing becomes more calm, all signs that you are into sleep.
01:01But here is where it gets fascinating, sometimes your brain gets a bit confused during that transition.
01:07One theory scientists propose is that as your muscles relax, your brain misreads that sensation
01:11as you actually fall.
01:13It is like your brain suddenly thinks, where are we falling?
01:16And sends a quick signal to your muscles to react, and that is the jerk you experience.
01:20It is similar to when you are on a roller coaster, and that initial drop makes your stomach flip
01:25the signals, don't always align with what is really going on.
01:28Only in this situation, it is your brain and muscles trying to switch from being awake to sleep.
01:33That mismatch can create the intense feeling of falling or floating just before the jerk wakes you up.
01:38There is even a fascinating idea that this might be something we inherited from our ancient
01:42ancestors.
01:43When the brain detected too much muscle relaxation, it would send a troll to wake the sleeper just in case.
01:48So, you could say your happening jerk is a little survival tool from way back.
01:52But why does it feel so intense?
01:54Well, your brain can still be somewhat awake during that initial state of sleep.
01:58While your body is unwinding, parts of your brain remain active and are trying to make sense of
02:02everything.
02:03That half-awake state can blend real sensations with dream-like images.
02:06So, your brain might quickly create a story like falling into a hole right as your body ducks back.
02:11Now, let's clarify, happening jerks are normal and usually not a sign of anything wrong.
02:16However, you might notice they occur more frequently when you are stressed, overtired,
02:20have consumed too much caffeine or when you don't stick to a regular sleep schedule.
02:24If these jerks happen all the time and keep you awake or make you anxious,
02:28it is worth discussing with a doctor.
02:30But for most people, it is just one of those straight sleep quacks that your brain and body
02:35do while transitioning into sleep.
02:36So, the next time you feel like you are falling just before you fall asleep,
02:40remember this, it is your brain's cave of checking in as you drift off and even thought it might
02:45catch you off guard.
02:47It is almost always harmless.
