Sleep spindles are more than just a strange phenomenon that happens during sleep. They play an essential role in soothing PTSD anxiety and enhancing memory retention.

Brief bursts of brain activity during sleep known as sleep spindles could potentially help regulate anxiety in people with post-traumatic stress disorder (PTSD). Researchers believe that the study’s findings may be useful for people with anxiety disorders and are looking at non-invasive ways to harness the benefits of this sleep stage to relieve symptoms. The study also suggests that sleep hygiene, electrical brain stimulation, or prescription sleep medications could promote the sleep spindles associated with non-rapid eye movement 2 (NREM2) sleep and potentially benefit patients with stress and anxiety disorders.
