Sleep deprivation adversely affects the body in many ways, including:

  • Prevents the body from adequately refreshing itself
  • Stresses the nervous system
  • Impairs brain function
  • Increases blood pressure
  • Increases blood sugar
  • Increases moodiness
  • Increases cortisol production, a powerful stress hormone, to compensate for feeling tired

To name a few.

Consequently, sleep disruption and deprivation can cause many anxiety-like symptoms.

When you combine anxiety, stress, and chronic stress with sleep loss, the body can behave in many odd and symptomatic ways.

You can prevent this by getting regular good sleep (6.5 to 8 hours per night).

If your sleep is disrupted because of anxiety, stress, and hyperstimulation, broken sleep and hyperarousal can become a vicious cycle.

For more information about how to address sleep problems, visit our Sleep section (chapter 18) in the Recovery Support area.

The combination of good self-help information and working with an experienced anxiety disorder therapist, coach, or counselor is the most effective way to address anxiety and its many symptoms. Until the core causes of anxiety are addressed – which we call the underlying factors of anxiety – a struggle with anxiety unwellness can return again and again. Dealing with the underlying factors of anxiety is the best way to address problematic anxiety.
