Yes, the itching (pruritus) associated with Lichen simplex Chronicus is typically described as much worse at night.
Lichen simplex Chronicus (LSC) is a skin condition characterized by chronic itching and scratching, leading to thickened, leathery skin (lichenification). While the overall itching may be mild to moderate during the day, it often intensifies significantly during periods of rest or inactivity.
Understanding the Nocturnal Itch
According to reference information, the pruritus of Lichen simplex Chronicus is:
- Mild to moderate generally: During the day, the itching may be present but manageable.
- Subject to paroxysms: Sudden, intense bouts of itching can occur.
- Relieved by rubbing and scratching: While this provides temporary relief, it perpetuates the itch-scratch cycle characteristic of LSC.
- Much worse during inactivity: This is the key factor, particularly impacting sleep. The reference states, "Pruritus is usually described as much worse during periods of inactivity, usually at bedtime and during the night."
Why Might Itching Increase at Night?
While the exact reasons aren't fully understood, the increase in itching at night is commonly linked to:
- Lack of distraction: During the day, activities can distract from the sensation of itching. At night, with fewer distractions, the focus often shifts to bodily sensations, making the itch more noticeable.
- Physiological changes: Some theories suggest natural bodily processes during sleep or rest periods might influence skin sensations or the inflammatory response, potentially heightening the feeling of itch.
- Reduced external stimuli: The quiet and stillness of night can make internal sensations, like itching, more prominent.
Impact on Sleep and Life Quality
The severe nocturnal itching is a significant challenge for individuals with LSC.
- It can lead to difficulty falling asleep and frequent awakenings during the night.
- This results in poor sleep quality and daytime fatigue.
- The constant disruption of sleep can negatively impact overall mood, concentration, and quality of life.
Addressing the intense night-time itch is often a primary focus in managing Lichen simplex Chronicus to help improve sleep and break the itch-scratch cycle that exacerbates the condition.
