"Does Anxiety Keep You Up at Night? Exploring the Powerful Link Between Sleep and Anxiety"

May 5

Mental health challenges can turn even the simplest tasks into uphill battles. Things you once did effortlessly—like falling asleep—can become exhausting as you try again and again without success.

Sleep is often one of the first things affected by anxiety. If you struggle to fall asleep, stay asleep, or wake up feeling rested, you’re far from alone.

Anxiety and sleep are deeply intertwined. Think of it as a vicious cycle: anxious thoughts can keep you from getting restful sleep, while lack of sleep can heighten anxiety. One feeds the other.

Stress, worry, and anxiety don’t just affect your daytime mental health—they can wreak havoc on your nights too. The good news? Treating anxiety has been shown to improve sleep and reduce the time it takes to fall asleep.

Let’s explore how anxiety and sleep influence one another—and how managing anxiety can help you get the rest your mind and body need.

What Is Anxiety?

To understand how anxiety impacts sleep, it's helpful to first understand what anxiety really is.

There are several types of anxiety disorders, but Generalized Anxiety Disorder (GAD) is the most common and wide-ranging.

Anxiety is both a physical and emotional experience marked by feelings of unease, nervousness, and stress. While some people experience anxiety in response to specific triggers, others—especially those with GAD—may feel anxious with no clear cause.

Common emotional symptoms of anxiety include:

Irritability
Feeling on edge
Anger or restlessness
A sense of fear or dread

Physical symptoms can include:

Rapid heart rate
Chest tightness
Muscle tension
Upset stomach
Headaches
Sweating or trembling
Insomnia
Trouble concentrating

Everyone experiences anxiety from time to time—before a big presentation, a job interview, or a first date. But for people with anxiety disorders, the brain remains in a constant state of high alert. That ongoing tension can make it hard to relax during the day and nearly impossible to sleep at night.

How Anxiety Disrupts Sleep

Insomnia and other sleep disturbances are some of the most common symptoms of anxiety. Excess worry can make it difficult to quiet the mind, especially at night.

While someone with anxiety may have racing thoughts during the day, nighttime often intensifies them. Lying in the dark, in silence, makes it harder to distract yourself from worries and fears. This can lead to a state of hyperarousal, where the brain remains on high alert—making sleep elusive.

Hyperarousal isn’t unique to anxiety. It’s also seen in people with depression, PTSD, and OCD. In this state, your mind might replay past regrets, obsess over current challenges, or rehearse future "what-if" scenarios—often on a loop that keeps you awake.

But it’s not just the anxious thoughts keeping you up.

Over time, struggling with sleep can create sleep anxiety—a fear of bedtime itself. You may dread another night of tossing and turning, which only increases stress as bedtime approaches. This can reinforce the belief that “sleep is difficult,” further feeding the cycle of anxiety and insomnia

The Two-Way Street: How Sleep and Anxiety Influence Each Other—And What You Can Do About It

The relationship between sleep and anxiety is deeply interconnected. Just as anxiety can keep you up at night, poor sleep can significantly worsen anxiety. This two-way cycle can be difficult to break—but understanding it is the first step toward lasting relief.

Sleep plays a vital role in brain function. It helps us process emotions, store memories, and mentally reset for the next day. Without sufficient rest, the brain struggles to regulate emotions effectively, leading to increased stress, worry, and fear. One of the earliest signs of this cognitive strain is often heightened anxiety.

A lack of sleep also raises levels of cortisol, the body’s main stress hormone. When cortisol remains elevated, the body stays in a constant state of alert, which can intensify anxiety symptoms and even contribute to the development of anxiety disorders.

Research shows that individuals already dealing with anxiety tend to be more sensitive to the effects of sleep deprivation. Their emotional and physical responses to lost sleep may be stronger, amplifying the impact on their overall well-being.

The good news? This connection also points to a path forward: treating anxiety can help restore healthier, more restful sleep.

At our practice, we can help you explore the most effective therapeutic approach for your unique needs. Whether you benefit most from identifying and reframing unhelpful thought patterns, processing unresolved emotions or trauma, or learning practical strategies for sleep and stress management, we’re here to support you every step of the way.

One of the most proven methods is Cognitive Behavioral Therapy (CBT). CBT can help you identify the thought loops and behavioral patterns that keep your mind active at night and prevent deep, restorative sleep. Your therapist will work with you to develop personalized tools to shift those patterns in a sustainable way.

CBT may also involve lifestyle and environmental adjustments—such as improving your sleep hygiene or creating a calming bedtime routine—that support your ability to wind down. Over time, this approach can quiet intrusive thoughts, lower anxiety levels, and help your brain settle into a state of restfulness.

Final Thoughts

Sleep isn’t a luxury—it’s essential for your mental and emotional health. If anxiety is keeping you up, or if poor sleep is fueling your anxiety, know that you don’t have to face it alone.

Reach out to your doctor or a licensed mental health professional to explore treatment options. Whether it’s CBT, relaxation techniques, or other targeted strategies, support is available—and it can make a meaningful difference in both your nights and your days.
