Do you find yourself getting frightened quite frequently? According to a new study published in The Journal of Neuroscience, people who get less REM sleep are likelier to become fearful in the face of a frightening event.
Moreover, people who get less quality sleep are also likelier to develop post-traumatic stress disorder. “We all tend to cut back on our sleep to do everything that's so important during the day,” University of Pittsburgh associate professor Anne Germain tells Live Science. “But by doing that, we're really cutting ourselves short and putting ourselves at a disadvantage when facing important life events."
