Falling asleep causes a number of different changes in your body. Your heartbeat slows down, your muscles start relaxing, and your breathing is different. This transition to sleep is commonly referred to as the hypnagogic period.

During this period, your body could experience twitching and sometimes muscle contractions. These muscle twitches are commonly referred to as myoclonus, and anyone can suffer from them. Our article highlights the causes as well as the simple life changes you can make to decrease hypnic jerks.

How do hypnic jerks feel like?

Hypnic jerks aren’t specific to one side or part of the body. It’s possible to experience a few muscle contractions or simply one at a time.

To many people, hypnic jerks are accompanied by sweating or irregular breathing. This is often accompanied by a tingling pain or a sensation of flashing lights or banging sounds. Some people have also reported experiencing hallucinations.

What causes hypnic jerks?

Experts are still not entirely sure of the exact reasons why people experience hypnic jerks. One of the working theories is that nerves send incorrect signals to your legs or arms as you fall asleep.

Another common medical theory is that the brain incorrectly misinterprets muscle relaxing as falling and, in turn, causes the muscles to twitch.

There are, however, a few common triggers that could increase the chances of experiencing hypnic jerks.

Caffeine and nicotine overconsumption

There’s a good reason why doctors and other health experts recommend you cut down on any caffeine or smoking in the hours before bedtime. Caffeine is well known to cause anxiety as well as increase insomnia episodes. When either caffeine or nicotine are regularly consumed in large quantities, the risk of hypnic jerks is increased.

Too much exercise at night

Evening exercise too close to bedtime has been known to trigger hypnic jerks. This is especially the case for people who have a rigorous exercise regime that doesn’t allow for adequate downtime between exercise and sleep.

Sleep deprivation

Hypnic Jerk: What Is It and Should You Be Worried About It?
People often underestimate the necessity for regular and healthy sleep.

Irregular sleep patterns or severe cases of insomnia can cause you to experience hypnic jerks more frequently and more severely.

Stress and anxiety

People experience stress or anxiety for different reasons. Depending on the severity of the anxiety, this can contribute to sleep deprivation. It becomes a vicious circle when the hypnic jerks are the reason for the anxiety.

Are hypnic jerks dangerous?

For the most part, hypnic jerks are harmless unless a twitch causes you to accidentally injure yourself. While there’s generally no physical harm from hypnic jerks, they can have an emotional effect.

Frequently experiencing hypnic jerks and not knowing what they are or what causes them can lead to anxiety about going to sleep. This, in turn, contributes to an anxiety disorder. Struggling with anxiety at bedtime also leads to sleep deprivation, which in itself can be harmful.

When to see a doctor

Hypnic jerks themselves won’t really need to be treated. Most medical specialists consider them to be a normal part of the sleeping process. If you find that your hypnic jerks are causing you excessive anxiety or resulting in sleep deprivation, you could consult your doctor.

Generally, a doctor deals with hypnic jerks by doing further tests to make sure the muscle twitches are, in fact, hypnic jerks. Often, a patient might think the muscle twitches are just hypnic jerks, but it could actually be something more serious such as restless leg syndrome or even epilepsy. They’ll then suggest ways for you to learn to manage and cope with hypnic jerks.

How to prevent it

While hypnic jerks aren’t necessarily something to be concerned about, they can be overwhelming to the people dealing with them at night. Fortunately, there are a few basic lifestyles changes you can make that will help you deal with hypnic jerks. The good news is there’s no need for extensive medical treatment or medications. Read on for a few tips to help you deal with hypnic jerks.

Improve your sleeping habits

Hypnic Jerk: What Is It and Should You Be Worried About It?
Few people realize the negative impact not having a healthy sleeping pattern can have.

While some of the anxiety you feel might be caused by the anticipation of hypnic jerks, it’s important to improve your sleeping habits.

If you feel your sleeping habits might be the primary cause of your hypnic jerks, consider making the following changes:

  • Sleep in a well-ventilated room: Sleeping in small, closed rooms increases CO2 buildupbuild-up. This affects proper sleep. Ensure your room is always ventilated to minimize CO2 buildupbuild-up.
  • Reduce light sources: Part of having a good night’s sleep is to reduce the amount of light around you when you’re going to bed. Minimal or no light during sleep time increases melatonin which in turn results in better sleep. This, in conjunction with changing your sleeping position, will go a long way toward a more comfortable and uninterrupted sleep.
  • Avoid sugary meals: Having something sugary before bed increases your energy levels, making it difficult to fall asleep. High blood sugar levels will cause you to keep waking up. Instead, focus on eating fruits like bananas before bed to aid sleep.
  • Create a routine: Try to create a bedtime routine that you can stick to. Go to bed at the same time every day and calculate it so that you get a minimum of 8 hours of sleep. Part of a routine includes having your last meal no later than 6 pm.
  • Invest in a new mattress: Another simple way to improve your sleeping patterns involves sleeping on the right mattress. The Amerisleep AS3 is tailored to adapt to most body types. This impressive mattress has great support to provide you with pain-relieving comfort and support.

Avoid caffeine

Hypnic Jerk: What Is It and Should You Be Worried About It?
Caffeine might be the ideal way to wake up in the morning, but it’s not the best drink for late evenings.

If you’re an avid coffee or soda drinker, it might be a good idea to switch out your afternoon and evening caffeine drinks with water or fruit juice.

If you drink a lot of caffeine, it might be difficult to stop cold turkey, adjusting your lifestyle from one day to the next. A simple way to reduce your caffeine intake is to start by switching to fruit juice after 5 in the afternoon. After a few days, stop your caffeine intake at 3 pm. That should give your body time to adjust to the lower caffeine intake.

Avoid nicotine and alcohol

Many people enjoy a glass or two of alcohol Trusted Source Alcohol and a Good Night's Sleep Don't Mix According to the findings, alcohol does allow healthy people to fall asleep quicker and sleep more deeply for a while, but it reduces rapid eye movement (REM) sleep. And the more you drink before bed, the more pronounced these effects. REM sleep happens about 90 minutes after we fall asleep.

If you ordinarily have dinner just before bed, it’s a good idea to change your dinner time to at least 3 hours before bed.

Reducing the number of cigarettes you smoke before bedtime might assist with reducing the hypnic jerks. Start on day 1 by counting the number of cigarettes you have from the time you come home to the time you go to bed.

Reduce this amount on the 2nd day and then again on the 3rd day. Another suggestion would be to increase the period between smoking. Or, form a simple goal. For example, if you smoke 20 cigarettes every day, discipline yourself to have only 10.

Ideally, you should avoid nicotine altogether, but that isn’t always as easy as it sounds! Smoking and drinking less every day will eventually have a positive effect on your level of hypnic jerks.

Final thoughts

Hypnic jerks don’t have to keep you awake at night. By following the tips and guidelines we’ve suggested, you can easily reduce the severity of your hypnic jerks. Knowing what they are, what causes them, and what you can do about them will take the stress and anxiety out of bedtime twitches! Now, sleep tight!
