Drug Abuse or Psychological Factors
The misuse or overuse of certain drugs can lead to severe sleep deprivation. Alcohol, caffeine, and hard drugs like cocaine or methamphetamine can disrupt one’s sleeping habit. These drugs are only designed for short-term use because the long-term effect can lead to serious health complications caused by severe sleep deprivation.
The excitement, anxiety, or nervousness of a new job or school may affect one’s ability to fall asleep. When you have a deadline or are writing an examination, you may also experience insomnia due to anxiety.
Emotional pain may also rid you of several nights of sleep. If you are grieving the loss of a partner, close friend, or relative, it may affect your sleep quality. Persons going through relationship heartbreaks may also find it difficult to rest their heads at night.
