Sleep Deprivation Leads to Mood Changes and Increased Anxiety, New Study Finds
Over 30% of adults have a daily sleep debt of over an hour, highlighting the widespread issue of sleep deprivation and its potential impact on mental health.
- Sleep deprivation, partial sleep loss, and sleep fragmentation all lead to emotional changes, with the most consistent effect being a reduction in positive mood.
- Sleep loss increases feelings of anxiety and results in more muted emotional responses.
- More than 30% of adults have a daily sleep debt of over an hour, and nearly 1 in 10 adults are missing two or more hours of sleep each night.
- Loss of sleep also worsens symptoms of anxiety and depression, even in people without known psychiatric or physical health conditions.
- Reactions to emotional experiences were more negative after loss of rapid eye movement (REM) sleep when compared with losing slow-wave or 'deep' sleep.
