Stress
Stress is one of the most common causes of hypnic jerks, as the nervous system becomes overstimulated, making them more frequent.
Alcohol
Alcohol can make you feel sluggish and can increase the frequency of hypnic jerks while the body metabolises it.
Fatigue
When you have been awake for too long, your body’s sleep-wake cycle is disrupted causing the hypnic jerks to occur more frequently.
Medications
Certain medications can also cause hypnic jerks as they affect the nervous system, leading to muscle twitching.
Caffeine
Drinking caffeinated beverages like coffee or tea before going to bed can overstimulate the nervous system, increasing the chances of hypnic jerks.
