Although anxiety stems from mental responses, it may cause physical symptoms and manifestations of anxiety. In addition to emotional feelings of stress and worry, anxiety can result in a physiological response that produces physical symptoms in your body.





Anxiety disorders, such as generalized anxiety disorder or panic disorder, can affect a person both mentally and physically.





Each person with anxiety will experience a different combination of symptoms.





Sometimes, temporary anxiety is an expected response to stress. However, clinicians may view anxiety as a disorder if it occurs over an extended period, causes substantial distress, or interferes with daily life. There are also different types of anxiety which vary based on their causes and how symptoms present.





This article will explain the physical symptoms of anxiety as well as how to treat them. It will explain how to differentiate physical symptoms of anxiety from other signs of illness. It will also answer some frequently asked questions about physical symptoms of anxiety.

Physical symptoms of anxiety can include:

  • dizziness, faintness, or weakness
  • tiredness or fatigue
  • palpitations, or a fast, strong, or irregular heartbeat
  • body pain, muscle aches, headache, or tension
  • trembling, shaking, or restlessness such as tapping or leg bouncing, known as psychomotor agitation
  • dry mouth
  • sweating, hot flashes, or chills
  • shortness of breath or a choking sensation
  • stomachache, nausea, or the feeling of butterflies in the stomach
  • a need to go to the toilet
  • paresthesia, or the feeling of pins and needles
  • insomnia, such as difficulty with falling asleep or staying asleep





The severity and duration of symptoms will vary from person to person. Some individuals may experience one or two symptoms, whereas others may experience a range or combination of effects.





There are a variety of different anxiety disorders that have different presentations. Physical symptoms may vary between types of anxiety, which have different characteristics.





Types of anxiety can include:





For example, physical symptoms of an anxiety attack or panic disorder may develop very suddenly. They are not necessarily due to a noticeable trigger.





Additionally, those with OCD may experience physical or sensory manifestations of compulsions. They may also experience other physical and mental symptoms, such as motor tics. For example, a person with OCD may have the mental compulsion to tap something a certain number of times.

Why does anxiety cause a physical response?





When your brain perceives stress or danger, your body triggers the nervous system. It then produces the fight-or-flight response to protect you.





This response causes the release of hormones called epinephrine and norepinephrine. They serve as messengers in your body by setting off physical reactions. These reactions are the symptoms of anxiety.





The fight-or-flight response is sometimes an expected and typical response to a threat. However, anxiety can trigger this response more often or in response to additional triggers. Anxiety symptoms or the fight-or-flight response may become frequent, disruptive, or chronic. This may indicate an anxiety disorder rather than a typical response to fear or stress.





Contact your doctor regarding new physical or psychological symptoms of anxiety. Physical anxiety symptoms can impact your quality of life and cause distress, so seeking medical support is important.





Although everyone experiences feelings of stress and anxiety from time to time, chronic anxiety symptoms could improve with care. Symptoms that are frequent, interfere with daily life, or do not easily resolve may indicate such a condition.





Additionally, some cases of anxiety may present an increased risk for other physical health problems. For example, researchers from a 2016 study suggest that anxiety can influence heart health.





Researchers also note that diagnosis and treatment for anxiety can improve health outcomes and quality of life.





It can be hard to know when your physical symptoms are the result of anxiety or a different disorder.





This can be distressing for those who experience anxiety. Concern about your health may further trigger symptoms or cause worry. The National Institute of Mental Health notes that these worries can cause a vicious cycle of panic. This can present as a person worrying that they are experiencing a medical emergency. This person then experiences more stress, causing further physical symptoms of anxiety.





However, there are a few differences that may help identify whether your symptoms are due to anxiety or a different health condition.





With anxiety, you may notice that your physical symptoms have a particular trigger. For example, if you have a phobia, your symptoms may occur with exposure to what you fear.





Additionally, panic attacks typically resolve within 20–30 minutes and your symptoms may improve from that point.





By contrast, medically urgent causes of symptoms worsen over time instead of improving gradually. For example, a heart attack may cause worsening symptoms of rapid breathing or palpitations. A heart attack may also cause pain or pressure in the chest. This pain can radiate to the arm, jaw, or shoulder, and can occur during or after physical activity.

Seek medical help for the following symptoms






Panic or anxiety attacks do not typically require hospital attention.





However, it is advisable to seek medical help for the following symptoms:

  • a panic attack that continues for more than 20 minutes
  • feeling unwell after breathing returns to normal
  • persistent rapid or irregular heartbeat, even after feelings of panic subside
  • severe pain anywhere in the body





This is in case there is an underlying physical cause of your symptoms. A medical team will then be able to check for serious illness and give you appropriate care.

Tips for how to relieve physical symptoms of anxiety





Self-management and care techniques can help to alleviate the physical symptoms of anxiety.





These techniques include:

  • breathing and relaxation exercises
  • meditation or mindfulness
  • exercise or physical activity
  • eating a balanced diet
  • noting the onset of your symptoms and any possible triggers
  • seeking support from your family, friends, or peers
  • trying to improve your sleep quality, for example by:
    • going to bed at the same time every day
    • avoiding using electronics before bed or in the bedroom
    • avoiding consuming caffeine, alcohol, or large meals just before bed
    • making sure your sleep environment is quiet, dark, and relaxing
    • allowing time to sleep for at least 7 or more hours each night





Self-management alone may not be enough to alleviate your symptoms of anxiety. If this is the case for you, a doctor can help you to access more effective treatments.





The most appropriate and effective treatment may depend on the cause of your anxiety, type of anxiety disorder, and your symptoms.





Generally, clinical treatment for anxiety can include:

  • medication
  • psychological therapies such as:
  • applied relaxation
