What Causes Restless Sleep Every Night?

There are many possible causes of restless sleep. In many cases, multiple factors work together.

1. Stress & Anxiety

Stress is one of the biggest causes of restless sleep in the United States.

When stress levels rise, the body releases cortisol and activates the nervous system.

This can lead to:

• Racing thoughts
• Muscle tension
• Night waking
• Increased alertness

People dealing with:

• Work pressure
• Financial stress
• Relationship problems
• Burnout

often experience worse sleep quality.
