A good night's sleep
A good night's sleep is essential for our overall good health. Memories are cemented during sleep, and students are often reminded that they need to have good sleep habits to maximize their learning.
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.
