Can fever or illness trigger sleepwalking in children?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Fever and illness are known triggers of sleepwalking and sleep terrors in children, increasing the likelihood of these parasomnia episodes occurring during the night. When a child's body temperature rises or they feel unwell, disruptions to normal sleep cycles can prompt confused arousals from deep sleep, leading to walking, talking, or intense fear episodes they typically won't remember.

If your child is experiencing sleepwalking, night terrors, or unusual behaviors during sleep, it's important to identify whether an underlying illness, fever, or another factor may be responsible. Taking a free, instant, online symptom check can help you quickly understand potential causes, assess urgency, and confidently plan your next steps—whether that means monitoring at home or seeking medical care.

Explanation

When children have a fever or are ill, it can sometimes lead to sleep problems like sleepwalking or sleep terrors. This happens because fever can disturb the normal sleep patterns.

Key Points:

Sleep Terrors and Fever: According to research, fever can lead to acute sleep terrors in children. This means that when a child is sick and has a fever, they might experience these scary episodes during sleep more often.
Sleep Patterns in Children: Other studies show that sleep problems are common in school-going children, and illnesses can make these problems worse.

If you notice that your child is experiencing frequent sleepwalking or sleep terrors, it might be helpful to talk to a healthcare provider. You can also use Ubie's free AI symptom checker to help identify potential causes of your child's symptoms and determine whether medical attention is needed.
