Adherence
High trait sleep reactivity acts as a diathesis that significantly increases the risk of developing insomnia when exposed to naturalistic stress, specifically by amplifying the impact of stress-induced cognitive intrusion.
If you are prone to sleep problems, your risk of developing chronic insomnia is significantly higher if you tend to ruminate on stressors (cognitive intrusion). Focus on managing your cognitive response to stress (e.g., through CBT-I techniques) rather than just trying to avoid stressors, as your reaction to stress is the primary driver of sleep disruption.
Trait sleep reactivity significantly increased risk for insomnia (OR = 1.78; P < 0.01). Further, sleep reactivity moderated the effects of stress-induced intrusion (P < 0.05), such that the risk for insomnia as a function of intrusion was significantly higher in individuals with high sleep reactivity.
