According to the Anxiety and Depression Association of America (ADAA), anxiety is a reaction to stress. Its key markers are feelings of tension, worried thoughts, and physical changes such as elevated blood pressure.
Just like physical pain, in and of itself anxiety is not a bad thing: it signals that something is wrong. Temporary anxiety is normal and can even be considered healthy because it draws our attention to causes of stress that might need correcting.
But anxiety disorders – characterized by excessive and chronic reactions to stress – are mental illnesses. Anxiety disorders are, in other words, worry that sticks way past its usefulness to us — it does not go away and often gets worse with time.
According to the National Institute of Mental Health, anxiety disorders, including post-traumatic stress disorder, obsessive compulsive disorder, and a variety of phobias, are the most common types of mental illness experienced by Americans. They affect 40 million adults in the United States, or 18 percent of the population.
Many anxiety disorders negatively affect sleep – and vice versa. Doctors call them comorbid, meaning they go hand-in-hand. In other words, anxiety and sleep are connected via a self-reinforcing feedback loop. Feeling rested combats anxiety and feeling less anxious leads to sounder sleep. The converse is also true: insomnia feeds anxiety and anxiety keeps us up at night.
The Centers for Disease Control and Prevention (CDC) classifies short sleep duration as adults getting less than seven hours of sleep in a 24-hour cycle. The CDC associates short sleep duration with the development and management of chronic diseases such as Type 2 diabetes, cardiovascular disease, and depression.
The growing use and popularity of social media platforms is also linked to poor sleep quality and mental health issues like depression and anxiety. Studies show that adolescents who use social media, especially at night, experience poorer sleep quality and are more likely to experience high levels of anxiety and depression, as well as low self-esteem.
Another, perhaps unexpected, link between sleep quality and anxiety is Alzheimer’s disease. Researchers found that increased levels of anxiety can be a precursor to Alzheimer’s disease. Beta-amyloid is a protein in the brain that is associated with both insomnia and Alzheimer’s disease.
This protein disrupts communication between brain cells, eventually killing them. Individuals with insomnia, anxiety, and Alzheimer’s disease all show higher levels of beta-amyloid.
This guide examines the link between anxiety and sleep and covers several anxiety disorders that interfere with sleep and which can be alleviated with sleep: generalized anxiety disorder (GAD), social anxiety, obsessive-compulsive disorder (OCD), phobias, post-traumatic stress disorder (PTSD), panic disorder, and pediatric anxiety.
It offers solutions to sleep-deprived anxiety sufferers, including treatment options, online support forums, tips regarding healthy sleep hygiene and banishing anxious thoughts, and medical associations that can help.
Anyone who lost a night to insomnia on account of troubling thoughts has been where many chronic anxiety sufferers find themselves all too frequently. According to UC Berkeley researchers, lack of sleep plays a role in ramping up brain regions that trigger excessive worry.
Additionally, those who tend to worry too much are more vulnerable to sleep disorders. “These findings help us realize that those people who are anxious by nature are the same people who will suffer the greatest harm from sleep deprivation,” said Matthew Walker, a professor of psychology and neuroscience at UC Berkeley and senior author of the study.
Worry about lack of sleep becomes a self-fulfilling prophecy at times. Anxiety causes sleep loss, which in turn can provoke further anxiety in sufferers. The mechanism behind this phenomenon has to do with what researchers call anticipatory anxiety.
People prone to sleep deprivation worry that they might not be able to sleep, perhaps based on past experience. That worry fires up the brain’s amygdala and insular cortex, mimicking the neural activity seen in anxiety disorders. And then, because of that anticipatory anxiety, sleep becomes elusive.
Researchers at University of California Berkeley’s Sleep and Neuroimaging Laboratory found that when deprived of sleep, the brain reverts back to more primitive patterns of activity. What this means is that subjects kept awake were less likely to put emotionally-charged information in context.
The good news is found in the reverse. Doing the opposite–finding ways to get better sleep–presents us with a tried-and-true solution to alleviate anxiety. “By restoring good quality sleep in people suffering from anxiety, we may be able to help ameliorate their excessive worry and disabling fearful expectations,” says Dr. Allison Harvey, one of the authors of the study published in the Journal of Neuroscience.
People living with generalized anxiety disorder (GAD), also known as free-floating anxiety, are prone to an exaggerated sense of worry regarding everyday events. The worry tends to persist no matter the circumstances.
According to DSM-5, which is short for the fifth and the latest edition of the Diagnostic and Statistical Manual of Mental Disorders, if the excessive anxiety and worry about events or activities goes on for most days of the week for at least six months, it points to GAD.
The persistent chatter of generalized anxiety is a voice that’s difficult to quiet at bedtime. Fifty percent of patients diagnosed with generalized anxiety disorder have sleep disorders. Difficulty falling and staying asleep as well as walking up to panic attacks (sudden awakenings to intense anxiety, heart palpitations, shortness of breath, sweating or chills, and often the irrational fear of impending death) are common effects of GAD on sleep.
Determining that a patient has generalized anxiety disorder can be tricky because it often mimics and coexists with mental health illnesses such as phobias, depression, and PTSD. The persistence of excessive worry and the inability to control it for most days during the period of six months is a key marker of the GAD diagnosis.
The absence of a particular trigger or trauma is also a distinguishing marker. For more features used by doctors to diagnose GAD, the questionnaire provided by the ADAA can be of help.
Getting better rest at night can do wonders for the symptoms of free-floating anxiety. Sleep researchers at Harvard have found that consolidated slumber throughout a whole night, in all its stages, helps people learn and make memories while impaired sleep reduces the ability to focus and acquire new information.
In turn, treating the symptoms of GAD can lead to better sleep because an effective treatment diminishes restlessness and helps gain control of worry.
Psychotherapy, such as cognitive behavioral therapy or mindfulness therapy, helps patients learn skills (such as distraction, detachment from negative thoughts, cognitive restructuring, exposure therapy) with which they can learn to abort obsessive worry.
Antidepressants (particularly SSRIs) can help, over time, to influence the activity of neurotransmitters in the brain—serotonin, dopamine, and norepinephrine–by increasing their presence. These neurotransmitters are responsible for maintaining mood balance and helping people put concerns in context. It takes a few weeks of well-tuned and consistent use for antidepressants to render effective results.
Tranquilizers known as benzodiazepines – for example, Xanax, and Ativan – can in the meantime be used occasionally to prevent acute attacks of anxiety, such as panic attacks.
Some studies have found that, depending on the individual, talk therapy can be as effective as antidepressants.
DSM-5 defines social anxiety disorder as a “persistent fear of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others.”
The socially anxious person fears acting in a way that might be embarrassing or humiliating. The fear of judgment by others often leads to avoidance of social situations or attacks of anxiety in social contexts, interfering with the socially anxious person’s normal routine, relationships, and professional goals for the period of at least six months. Fifteen million American adults live with social anxiety disorder.
Because a good night’s rest is proven to stabilize people’s moods and emotional regulation, it is important for social anxiety sufferers to get enough sleep. Not enough sleep boosts anticipatory anxiety, which troubles the socially anxious in the lead-up to social situations, often preventing their ability to sleep at night.
According to UC Berkeley researchers, “By restoring good quality sleep in people suffering from anxiety, we may be able to help ameliorate their excessive worry and disabling fearful expectations.”
To be diagnosed with the disorder, persons must have persistent fear, anxiety, or avoidance that last for six months and interfere with their usual routine, occupational tasks, and relationships.
When diagnosing a patient, doctors sometimes confuse social anxiety disorder with panic disorders. The difference between the two disorders is underlying fears.
People with a panic disorder interpret their sudden anxiety attacks as something being physically wrong with them. They might, for example, believe that the tightness in their chest means that they’re having a heart attack or that they are about to suffocate to death.
Not so in the case of social anxiety sufferers, who do not see their heightened anxiety as a primarily physical issue. They see their anxiety, provoked by social interactions, as the underlying fear.
Socially anxious individuals have anxiety that significantly worsens when they are in a situation where they fear they are going to be singled out, made fun of, embarrassed, or criticized.
It is important to note that people living with social anxiety are not deluded: they recognize this fear as unreasonable and excessive. Yet, they act on this fear they know to be irrational by avoiding social situations or becoming very anxious when socializing.
Like in cases of other anxiety disorders, both talk therapy and medications have been found helpful to the socially anxious.
Cognitive behavioral therapy has been proven effective in many cases. Often therapists will try to get at deeply seated roots of the problem (which, for example, may have to do with family background or history of having been bullied).
In practical terms, they can conduct exposure therapy, in which patients prepare for and are put in social situations that challenge them. Some studies have found that, depending on the individual, talk therapy can be as effective as antidepressants.
Antidepressants (particularly SSRIs) can help, too, by increasing the presence of neurotransmitters (serotonin, dopamine, and norepinephrine) in the brain, which in turn allows for mood management; people treated with antidepressants are then better able to internalize the rational arguments against social anxiety disorder – for example, that few people take the time to scrutinize us when we make a comment at a cocktail party.
It takes of a few weeks of well-tuned and consistent use for antidepressants to render effective results. Tranquilizers known as benzodiazepines – for example, Xanax and Ativan – can in the meantime be used occasionally to prevent acute attacks of anxiety, such as panic attacks.
The socially anxious patient who has a speaking engagement can benefit from taking a benzodiazepine prior to that occasion. Beta blockers block adrenaline, which can reduce the physical symptoms of social anxiety such as shaking voice, elevated heart rate and blood pressure, excessive sweating, and the pounding of the heart.
Obsessive-compulsive disorder, or OCD, is a chronic pattern of unwanted, unreasonable, and repetitive thoughts, feelings, ideas, mental images, or sensations (obsessions) that drive people to repetitive behaviors (compulsions).
About 2.2 million American adults live with OCD, which often coexists with eating disorders, other anxiety disorders, or depression.
While sleeping issues are not considered core to OCD, some research indicates that intrusive thoughts do keep people with OCD up at night.
Everyone double-checks things and some people prefer more order than others. OCD-afflicted persons, however, stand out because of their inability to control the thoughts that they know to be unreasonable and because of how much time (often an hour a day) they devote to the OCD-driven ideas and activities.
The rituals and behaviors bring a fleeting relief from anxiety, but do not give them pleasure. If you are a collector of things, for example antiques, and take pleasure in tracking them down and organizing them, you do not have OCD.
In diagnosing OCD, therapists look for obsessions, compulsions, and how much time they take as well as how much they interfere with the person’s normal daily pursuits, professional life, and relationships. DSM-5 teases out OCD’s diagnostic criteria.
It can sometimes be difficult for therapists to diagnose patients with OCD because of symptoms that hide (such as compulsive avoidance) and because patients are sometimes so horrified or embarrassed by their thoughts, feelings, or behaviors that they hide them from the therapists.
Like with other anxiety disorders, cognitive behavioral therapy (CBT) has shown to be effective in case of the OCD. In particular, a type of CBT called Exposure and Response Prevention Therapy (ERP) works well with OCD-afflicted patients. It relies on exposing the patient to the situation that normally triggers OCD behaviors and helping them learn to forgo these behaviors.
Along with ERP, antidepressants from the serotonin reuptake inhibitors group, are considered the first line of treatment for OCD. About 7 out of 10 people with OCD get relief from medication or ERP.
Phobias are intense, persistent, irrational fears regarding an object, place, or situation. The fears that animate them are disproportionate to the threat posed by the triggering situations.
The paralyzing fears can lead to intense discomfort, anticipatory anxiety, avoidance of triggers, and panic attacks. The most common phobias include archanophobia (fear of spiders), ophidiophobia (fear of snakes), archophobia (fear of heights), agoraphobia (fear of open spaces often developed by people with social anxiety), and claustrophobia (fear of small spaces).
The DSM-5 splits phobias into three categories:
Specific phobias affect 19 million Americans, with women being twice as affected as men.
Much like with other anxiety disorders, phobia sufferers are advised to get good sleep. That can be tricky, to say the least, for those with somniphobia, also known as hypnophobia, which is the irrational fear of sleep.
People afraid to fall asleep are advised to practice healthy sleep hygiene, challenge negative beliefs, meditate, practice deep breathing, and follow other relaxation techniques to learn to feel relaxed and safe before falling asleep. If sleepwalking or sleep apnea are causes of somniphobia, these underlying causes need to be treated first.
Diagnosing phobias often means that the therapist will inquire about the source of fears and compare them against the list of phobias provided in the DSM-5.
It can be difficult to differentiate phobias from other disorders with fears of objects of situations at their cores (for example, schizophrenia, paranoia, OCD). Paranoia can cause avoidance, much like agoraphobia and social phobias. However, absent in phobias are attributions of ill intent onto others (present in paranoia) and the hallucinations (present in schizophrenia).
The paranoid and schizophrenic believer their fears to be rationally based, whereas the phobic know that their fears are unreasonable but are nevertheless unable to control them. And, unlike people living with OCD, people with phobias do not obsess on them and do not act compulsively.
ERP, or therapies featuring exposure to the feared stimuli – such as flooding, systematic desensitization, progressive relaxation, virtual reality immersion, hypnotherapy, counter-conditioning, biofeedback, and modeling – have been proven effective in cases of phobia.
While exposure therapy is successful on its own, sometimes initial or occasional use of medications can also help. Some doctors recommend short-term use of sedatives in specific, infrequent situations (such as flying on an airplane or giving a speech) such as the fast-acting and short-lasting benzodiazepines.
Beta blockers, which block the effects of adrenaline (increased heart rate, sweating, shaking voice), are also commonly prescribed for phobias.
Self-help methods can also work, sometimes on their own. For ideas, see this Help Guide page.
PTSD is a potentially debilitating disorder that results from a shocking, terrifying, or dangerous event or series of events. People living with PTSD have difficulty recovering from trauma, and often reexperience it over and over. They feel stressed or frightened anew each time something brings trauma to mind–even when they are no longer in danger.
About 7.7 million Americans aged 18 and older have PTSD. Common with war veterans, the disorder is suffered by 67 percent of people exposed to mass violence. Rape is the most likely culprit behind PTSD: 65 percent of men and 45.9 percent of women who are raped are diagnosed with the disorder.
PTSD commonly robs people of sleep, sometimes inducing a sleep phobia, because of the nightmares that are common with this condition.
To be diagnosed with PTSD, patients have to report the symptoms listed in the DSM-5 in conjunction with the history of having experienced or witnessed in person a traumatizing event such as death, serious injury, or sexual abuse.
Another qualifying history is the patients’ having learned that someone close to them experienced or was threatened by a traumatic event. Finally, the repeated exposed to graphic details of traumatic events (for example, in cases of professional first responders) also qualifies as PTSD-initiating history.
Unfortunately, PTSD can be sometimes confused with Traumatic Brain Injury. In most instances, it occurs at the same time as other disorders (such as depression).
Like with other anxiety disorders, the effective treatments for people living with PTSD are medications, talk therapy, or both. The types of psychotherapy found useful are exposure therapy, eye movement desensitization and reprocessing (EMDR), group therapy, and family therapy.
In addition to SSRI antidepressants (longer-term stabilizers of emotional responses) and tranquilizers (short-term anxiety reducers), doctors sometimes use second-line for PTSD include the drug Prazosin (Minipress). The medication has been found to decrease nightmares and a reduction in daytime PTSD symptoms.
This effect–observed in a 2013 study of active – duty soldiers returned from Iraq and Afghanistan – is attributed the blocking by the drug of the animating neurotransmitter norepinephrine.
Panic disorder is an illness characterized by sudden, out-of-the-blue onsets of severe anxiety and panic attacks. The physical symptoms of this acute terror include panic attacks, which manifest as chest pain, heart palpitations, shortness of breath, dizziness, or abdominal distress.
The attacks are defined as periods of “intense fear in which 4 of 13 defined symptoms develop abruptly and peak rapidly less than 10 minutes from symptom onset.” Persons with panic disorder can have between several attacks per day to several per year.
Panic disorders affect 6 million Americans, or 2.7 percent of U.S. population. Most of the sufferers are women.
Panic attacks can happen during the night, serving a cruel wake-up. Between 50 and 70 percent of people with panic disorder experience at least one nocturnal panic attack. As with the daytime attacks, the nocturnal ones cause the same symptoms and can have no discernable trigger. There is some evidence, however, that sleep disorders themselves can trigger nocturnal panic attacks.
It can be understandably hard to return to sleep following a panic attack, but the way to do it is still the same as with getting to sleep at a regular time.
Panic disorder can be confused, by the sufferers themselves, for hypochondria. They can experience shame over having gone to the emergency room fearing death only to learn that there is nothing physically wrong with them. This sometimes prevents them from seeking help.
When they do seek help, people living with panic disorder are diagnosed based on the DSM-5 criteria. Panic disorder is diagnosed in case when panic attacks do not result from substance use (intoxication or withdrawal), other medical conditions, or another psychiatric disorder (for example, PTSD or social anxiety, which can both produce panic attacks).
Panic disorder is often diagnosed as “with agoraphobia” or “without agoraphobia” because agoraphobia means that people with panic attacks avoid ordinary activities or situations because they worry about having panic attacks. A very small minority of people with agoraphobia become completely home bound.
There’s hope when it comes to panic. According to ADAA, “many people suffering from panic attacks don’t know they have a real and highly treatable disorder.” People who experience panic do not need to be in therapy for a long time.
Cognitive therapy can help people identify triggers and thus restructure the way they think and respond to various stimuli. Sometimes the therapy takes the form of interoceptive exposure, which focuses desensitization on physical sensations that people experience during a panic attack.
According to American Psychological Association, interoceptive exposure can help patients undergo symptoms of a panic attack (elevated heart rate, hot flashes, etc.) in a controlled setting and teach them that these symptoms do not need to develop into a full-blown attack. Another technique is in vivo exposure, in which the threatening stages are broken down into tiny, manageable steps and the patient learns to gain control of each one.
About 7 percent of children aged 3-17 have diagnosed anxiety, approximately 4.4 million. Within the first weeks after birth, children can develop anxiety disorders beginning with fear of loss, such as not being in physical contact with a caregiver. Starting at six months, infants may begin to show signs of separation anxiety and cry when left alone in their crib at night. Toddlers may develop specific phobias like fear of animals, storms, or the dark.
At 2-3 years old children can experience panic attacks. The most common anxiety disorders seen in children are specific phobia, social phobia, generalized anxiety disorder (GAD), and separation anxiety disorder. Post-traumatic stress disorder (PTSD), panic disorders, and obsessive–compulsive disorders are relatively rare in children.
Parents and teachers may be the first to notice signs of a pediatric anxiety disorder. It’s common for children to not want to talk about anxieties, as avoidance is a standard coping mechanism. Additionally, parents may classify their child’s behavior as a phase or something that will be outgrown.
Some anxiety disorders in children have a duration specification. A social phobia or specific phobia, for example, must occur for six months or more to be officially diagnosed as an anxiety disorder. Physicians agree that diagnosing anxiety disorders in children can be difficult, but questionnaires and guidelines have significantly improved within the last two decades.
Treatment for childhood anxiety disorders typically consists of cognitive behavior therapy (CBT) or pharmacotherapy (meaning using medications as treatment), with CBT being the preferred method and the first line or treatment.
Some children will respond best to a combination of both treatment options. Approximately two-thirds of children treated with CBT will become free of their anxiety diagnosis post-treatment.
Parents supporting children with anxiety can follow a few tips to help with managing their anxiety.
People with anxiety disorders are in particular need of sleep. Getting good rest at night can help stabilize mood, improve cognitive functioning in areas of learning and memory, and promote the kind rational thinking we all need to put fears and concerns in context.
Here are five tips that can help you fall asleep in spite of anxiety:
