Do you sometimes feel a sudden jolt right before you go to sleep that can startle you? Occasional body jerks or twitches as you fall asleep are usually harmless and considered a normal part of the sleep process. However, it’s important to know what are the reasons behind your body jerking right before you fall asleep.

Sleep jerks

These are called Hypnic Jerks

These are involuntary muscle twitches or spasms that occur as you transition from wakefulness to sleep. They are often characterized by sudden, brief jerking movements, and can sometimes be accompanied by a sensation of falling. Hypnic jerks are believed to be a normal part of the sleep-wake transition and typically occur during the early stages of sleep. 

1. Stress and Anxiety

Stress and anxiety can disrupt the natural sleep process and lead to increased muscle tension, which may contribute to muscle twitches or jerks as you try to relax and fall asleep. Anxious thoughts or worries can also cause your body to become more alert, making it difficult to transition smoothly into sleep. 

2. Caffeine

Consuming caffeine or other stimulants close to bedtime can interfere with your ability to relax and fall asleep. Stimulants can increase arousal and make it more likely for your muscles to twitch or jerk as you try to drift off to sleep.

3. Irregular Sleep Schedule

Having an irregular sleep schedule or not getting enough sleep can disrupt the natural sleep-wake cycle and increase the likelihood of experiencing muscle twitches or jerks as you fall asleep. Consistently getting an adequate amount of sleep and maintaining a regular sleep schedule can help reduce the occurrence of these involuntary movements. 

4. Sleep Disorders

Certain sleep disorders, such as periodic limb movement disorder (PLMD) or restless legs syndrome (RLS), can cause repetitive or rhythmic muscle movements during sleep. These movements can sometimes occur as you are falling asleep and may manifest as jerking or twitching sensations.

5. Temperature Changes

Sudden changes in temperature or environmental conditions, such as feeling too hot or too cold, can trigger muscle twitches or jerks as your body adjusts to the changes while falling asleep. 

It’s important to relax, meditate, do gentle yoga and deep breathing for easy sleep. However, if these movements occur frequently or disrupt your sleep on a regular basis, it may be helpful to consult with a healthcare professional to rule out any underlying sleep disorders.
