Early to Bed Leads to Fewer Negative Thoughts.
A study that included 100 college students found that those who went to bed later and slept fewer hours experienced more repetitive negative thoughts during the day than those who went to bed earlier and slept longer. Study author Dr. Jacob Nota adds, “Making sure that sleep is obtained during the right time of day may be an inexpensive and easily disseminable intervention for individuals who are bothered by intrusive thoughts.”
