Do You Twitch as You Fall Asleep? Here's What Your Body's Trying to Tell You

Maybe you've had a rough day and are looking forward to cozying up in bed. As you blissfully doze off, though, you're suddenly woken up by a sensation of your arms and legs jerking. You're awake again and, in your sleepy haze, wondering what just happened.

"This is called a hypnic jerk, or a sleep start,"Raj Dasgupta, MD, an assistant professor of clinical medicine at Keck Medicine of USC in Los Angeles, California, tells LIVESTRONG.com. "As you're falling asleep, you get this feeling like a jolt of electricity."

It's not a seizure, and it's a totally benign occurrence. And it's common, too —up to 70 percentof people experience hypnic jerks (which are sometimes called hypnagogic jerks). You might also get the impression that you're falling as you have them.

While they're nothing to worry about, they can serve as a clue that something's off with your lifestyle or that you could use a little self-care. Here's what might be going on:

When it comes to hypnic jerks,sleep deprivationis the most common cause, Dr. Dasgupta says. "This might be that you're not getting a good quantity or quality of sleep," he explains.

Poor quality sleep means you're not getting the deeper REM stage of sleep that's restorative. How can you tell? Despite being in bed — seemingly sleeping — for the seven to nine hours recommended by theNational Sleep Foundation, you mightwake up feeling unrefreshedand be sleepy during the day.

To address sleep deprivation, make sure you're giving yourself enough time in bed in order to get the minimum seven hours — set a "go-to-bed" timer if it helps to remind you. Sleep hygiene, such as having time before bed for relaxing activities and staying away from screens (yes, that includes scrolling on your phone), is also important for sleep quality, Dr. Dasgupta says.

Mental and emotional stress can also trigger asleep start.

"It would be very interesting to know if people started experiencing more hypnic jerks during the pandemic," Dr. Dasgupta says.

This plays perfectly into the idea that you could use some relaxation or wind-down time before bed to ease any anxieties that might be keeping you awake and physically relax so you can fall asleep peacefully.

Stimulants, such as caffeine and nicotine, are also associated with hypnic jerks, Dr. Dasgupta says. And it's no surprise that sleep deprivation and caffeine consumption can go hand in hand.

The more sleep-deprived you get, the more you might rely on caffeine to keep you awake, and you may drink it later in the day (disrupting your sleep even more). TheU.S. Food & Drug Administrationrecommends people consumeno more than 400 mg of caffeinedaily, or four to five cups of coffee (we're talking about 8-ounce home-brewed cups, for the record).

Because hypnic jerks happen during the transition between wake and sleep, they may be more likely to occur if you have sleep apnea, a condition marked by brief pauses in breathing throughout the night, which causes multiple arousals and awakenings, Dr. Dasgupta explains.

Other signs and symptoms of apnea include snoring or gasping during sleep (something your bed partner might notice), as well as excessive daytime sleepiness or当你醒来头痛, according to theNational Heart, Lung, and Blood Institute. Sleep apnea is dangerous because it can increase your risk of heart disease andtype 2 diabetes, so talk to your doctor.

Classic symptoms of RLS include uncomfortable sensations in your legs when going to bed that are usually relieved by stretching or moving your legs. RLS can affect sleep by keeping you awake and contributing to insomnia.

Another type of twitching or movement you might experience is called periodic limb movement disorder (PLMD). These limb movements occur at night and usually involve the legs, Dr. Dasgupta says, adding that though they're usually not harmful, they may wake you up during the night, causing fatigue the next day.

Many people who have PLMD also have other conditions such asRLSor obstructive sleep apnea. If these nighttime leg twitches are cutting into your sleep, talk to your doctor, who may want to see you to rule out underlying conditions. If you do haveRLS and PLMD, there are medications that can help, as can avoiding caffeine.
