Does anxiety cause insomnia?

Yes. Anxiety triggers hyperarousal and racing thoughts that interfere with sleep. The resulting sleep deprivation then worsens anxiety, creating a vicious cycle.

Can poor sleep cause anxiety?

Yes. Sleep deprivation impairs emotional regulation and increases anxiety sensitivity, making people more vulnerable to anxiety symptoms.

What treatments address both anxiety and insomnia?

CBT-I (cognitive behavioral therapy for insomnia) combined with anxiety treatment is effective. Sleep hygiene, mindfulness, and maintaining regular exercise help both conditions.
