Cause 5: Fever and Illness
When the body is under siege from pathogens, a fever is often its chosen weapon. A rise in temperature, while uncomfortable, is a sign that our bodies are fighting off invaders. But these increased temperatures can mess with our internal thermostat, which plays a role in regulating sleep. This disarray can lead to restless nights, and in some cases, nocturnal wandering. The exact mechanisms are still under study, but preliminary research suggests that high fevers, especially in children, can lead to sleep disturbances, including sleepwalking.
The body’s reaction to illness isn’t just limited to fevers. When we’re sick, a cascade of biochemical reactions unfolds, affecting everything from appetite to sleep. The brain, in its bid to manage the illness, might alter its neurotransmitter levels, leading to changes in sleep architecture. These shifts, though temporary, can create an environment conducive to sleepwalking, especially in those already predisposed to such episodes.
It’s not just that illness can disrupt sleep; the reverse is true as well. A disturbed sleep pattern, whether from sleepwalking or other causes, can weaken the immune system, making the body more susceptible to infections. This cycle, where poor sleep leads to illness and illness further disrupts sleep, can be challenging to break and underscores the importance of maintaining good sleep hygiene, even when under the weather.
Children, with their developing immune systems, are especially susceptible to infections and consequent fevers. This vulnerability, combined with a natural predisposition towards sleepwalking during developmental years, means that fever-induced noctambulism is more common in kids. Recognizing this link and ensuring a safe sleep environment becomes crucial during these feverish episodes. (5)
