Why Do I Feel More Anxious at Night?

Whether you’re ticking through tomorrow’s to-do list or dwelling on past regrets, it’s normal for worries and fears to surface at night, experts say. According to an October 2022 survey of 3,192 of adults in the United States, for instance, 34 percent of respondents reported feeling anxious or nervous within the past month. And 32 percent said that their stress had led to changes in their sleeping habits, including difficulties with falling asleep. There’s an evolutionary purpose to evening anxiety, said Dr. Rafael Pelayo, a clinical professor of psychiatry and behavioral sciences in sleep medicine.
