A good night’s sleep may help you manage fear and risks better.
A study just posted in Journal of Neuroscience describes the importance of a good night’s sleep to controlling strong emotions, especially fear.
Previous studies in this area attempted to discover what happens in the brain after a frightful experience. These prior studies, for example, show how Post-Traumatic Stress Disorder (PTSD) affects sleep. A team at the Rutgers University Center for Molecular and Behavioral Neuroscience, led by Itamar Lerner, has taken a different approach. They wanted to see if there is a relationship between adequate sleep and prevention or management of the brain’s reaction to subsequent stressful events.
Lerner is a Postdoctoral Fellow in sleep research. Along with fellow researchers Neha Sinha-also doing Postdoctoral research-in her case in brain imaging, Shira Lupkin and Alan Tsai, they used new technology that allows mobile tracking of sleep habits over a period of time, not just one night in a sleep lab. This research was overseen by Dr. Martin Gluck, Professor of Neuroscience and Co-Director of the Memory Disorder Project at Rutgers- Newark.
The research team noted that individuals getting a full night’s rest, including adequate Rapid-Eye-Movement (REM) sleep, has a preventive effect in the face of what might otherwise be a fearful, risky or frightful experience. This seems to be done by modulating the connections among the amygdala, hippocampus and ventromedial prefrontal cortex- all of which are areas of the brain involved in memory formation, emotions, the “fight or flight” response (and much more).

One More Reason
In previous posts, we’ve discussed the critical importance of a full, complete night’s sleep to brain health and peak mental performance at every age. This new research adds another reason to make sure that we develop good sleep habits.
Shameless plug: if you aren’t getting a restful night of sleep, perhaps a sleep mask might help. We offer a terrific one at the bargain price of $6.
