Yes. Anxiety increases cognitive and physiological arousal, making it harder to fall asleep and easier to wake up. Poor sleep then raises anxiety sensitivity, creating a reinforcing loop.
Why This Matters
This matters because the nervous system treats worry like threat, which leads to elevated heart rate, tension, and rumination at bedtime. Fragmented sleep results in lower emotional regulation the next day, making worries feel more convincing. Addressing both sides—sleep habits and anxiety skills—often leads to the fastest improvement.
Where This Changes
If sleep is disrupted by a medical cause (apnea, reflux, pain), anxiety may be secondary. If anxiety is severe, panic attacks occur, or sleep loss is prolonged, professional support and structured therapies (CBT, CBT-I) can be especially helpful.
