What causes sudden jerking movements as I fall asleep?

Hypnic jerks, also called sleep starts, are sudden, involuntary muscle twitches that can happen as you begin to fall asleep. These jerks are quite common and usually harmless. Various factors can increase the likelihood of experiencing hypnic jerks, including stress, anxiety, caffeine intake, and nicotine use.

1. Stress and Anxiety: High levels of stress or anxiety can make hypnic jerks more frequent. If you are experiencing mental health concerns, consider reaching out to resources like 988lifeline.org.

3. Other Factors: While not always linked to underlying health issues, hypnic jerks can sometimes be associated with sleep disorders or mood disorders, such as major depressive disorder.

Overall, hypnic jerks are a normal part of falling asleep for many people. However, if they become bothersome or are accompanied by other symptoms, consulting a healthcare provider might be helpful.
