<p><strong>A good night's sleep is essential for our overall good health</strong>. Memories are cemented during sleep, and students are often reminded that they need to have good sleep habits to maximize their learning.</p>
<p>New research shows that sleep is also vital for unlearning things (especially the things that we no longer need to fear). These findings may prove useful in helping those with or at risk of developing anxiety or post-traumatic stress disorder.</p>

A good night's sleep

Health

<ul>
<li>New research shows that that people without sleep fare better in learning what to fear and not fear than those getting only some sleep.</li>
<li>Test subjects learned to associate colors with electric shocks, but only some unlearned it.</li>
<li>The findings could be used to help create new treatments for those at risk of PTSD or anxiety.</li>

We know that sleeping is important for remembering things. It turns out it is important for forgetting them, too.

Getting plenty of sleep just became even more important.
