Four Key Words To Help You Improve Your Sleep
Researchers from Southern Illinois University, SUNY Buffalo, and St. Mary's College found that exposure to sleep-related words, such as "cozy," "calm," "rest," and "relax," positively affected participants' sleep. The volunteers slept 47 percent longer during a brief nap and also had a significantly lower heart rate during sleep (a sign of deeper rest, according to the researchers) compared to those exposed to neutral words.
In a followup study, rest-related words also helped people with sleep problems, leading the study's authors to say priming with these types of words could help people fall asleep more easily.
