Explanation

Sleep-Related Rhythmic Movement Disorder (RMD) involves repetitive movements during sleep, like head banging or body rocking. These movements are common in children and usually not harmful. However, if the movements are very strong or happen a lot, there is a chance of injury, like bumps or bruises.

What is RMD?

  • Common Movements: Head banging, body rocking, or head rolling.
  • Age Group: Mostly seen in children, but can occur in adults.

Is it Dangerous?

  • Usually Safe: Most of the time, the movements are not strong enough to cause harm.
  • Possible Injuries: If movements are very strong or happen often, there can be injuries like bruises or even more serious injuries if the person hits something hard.

When to Seek Help?

  • If the movements cause injury or if they are very frequent, it may be a good idea to talk to a doctor.
