Anxiety and panic disorders can cause a range of uncomfortable physical symptoms, including accelerated heart rate, sweating, shaking, trembling, and tense muscles. Experiencing frequent feelings of fear, worry, and anxiety can contribute to muscle pain and tightness, and muscle tension is a common problem for people with panic disorders. Muscle contractions can be caused by a variety of factors, including dehydration, malnutrition, lack of sleep, and caffeine consumption. In some cases, muscle contractions may be a symptom of an underlying condition such as stiff person syndrome (SPS), a rare neuroimmunological disorder characterized by rigidity and painful muscle spasms. While panic attacks are typically not life-threatening, it is important to consult a doctor for a proper diagnosis.

What You'll Learn
Muscle tension and anxiety
Anxiety can also cause muscle tension and pain by keeping muscles in a permanent state of tension, which, when concentrated in a certain area, results in a decrease in blood flow, preventing tissues from getting enough oxygen and blood. This can lead to muscle tissue ischaemia, which can cause stiffness, cramps, headaches, dizziness, and muscle pain.
In addition, people with anxiety are less likely to be active, which can deplete resources from the muscles, causing them to be over-excited and leading to contractions. Dehydration, which is also more common in those with anxiety, can also lead to muscle spasms.
Muscle twitching caused by anxiety can be prevented and managed in several ways. Firstly, getting 7 to 8 hours of sleep per night is important, as sleep deprivation can cause involuntary muscle movements. It is also important to avoid caffeine and other stimulants, which can keep the body in a hyperstimulated state, making it more susceptible to muscle spasms. Consuming a healthy diet with enough salt, calcium, and other micronutrients can also help, as malnutrition can decrease blood sugar and aggravate muscle twitching. Staying hydrated is crucial, as dehydration can lead to mild anxiety and make muscles twitch. Finally, reducing stress and trying relaxation techniques such as progressive muscle relaxation can help to calm and relax the body.

Adrenaline rushes and the fight-or-flight response
Adrenaline, also known as epinephrine, is a hormone produced by the adrenal glands, which sit above the kidneys. Adrenaline rushes occur when the body releases this hormone into the bloodstream very quickly, usually within minutes. This quick release of adrenaline is called an adrenaline rush.
Adrenaline rushes are typically triggered by certain situations, such as a stressful or dangerous event, and they can also occur during a panic attack. They can even be caused by dreams about stressful or dangerous situations. The release of adrenaline is part of the body's vital defence mechanism, triggering the fight-or-flight response to a perceived threat. This response helps prepare the body to cope with a dangerous or stressful situation.
During an adrenaline rush, the body experiences several physical changes, including an increased heart rate, increased blood pressure, and faster breathing. The body may also redirect blood towards the muscles, resulting in a surge of energy and shaking limbs. The airways may relax to provide the muscles with more oxygen, which can lead to shallow breathing. Adrenaline can also sharpen mental focus, allowing quicker thinking and the formation of a clear plan to escape a potential threat. Additionally, it can decrease the body's ability to feel pain and temporarily increase strength. These changes enable the body to react quickly to potential dangers.
The fight-or-flight response can be triggered not only by external stressors but also by internal factors such as anxiety and stress. People with anxiety disorders may experience frequent adrenaline rushes due to the excess release of adrenaline induced by their anxiety. This excess adrenaline can excite the nervous system, leading to muscle contractions and spasms. Anxiety-induced muscle twitches and contractions are common and can be involuntary, affecting various parts of the body. They can range from small twitches to cramps and can cause significant distress.

Dehydration and anxiety
While the exact causes are unclear, people with anxiety are more prone to dehydration. Dehydration can also increase feelings of anxiety and depression. This is because dehydration can directly impact brain function, disrupting neurotransmitters, stress hormones, and cognitive function, all of which influence anxiety.
Dehydration raises cortisol, the body's main stress hormone, triggering a physiological stress response. A 2024 study found that lower hydration levels were linked to higher cortisol levels and increased anxiety symptoms. Dehydration can also increase glutamate, a neurotransmitter that, in excess, can heighten anxiety and impair cognitive function.
Drinking plenty of water is important for maintaining your mental health. Water keeps your circulation flowing smoothly, aids with digestion and weight loss, eases joint movement, and helps your body absorb nutrients from food. Electrolyte-rich beverages can be particularly beneficial if symptoms of moderate dehydration are present.
Dehydration can also cause a host of other unpleasant physical symptoms that can bring down your mood, including headaches, fatigue, muscle cramps, and constipation.
In addition, dehydration can worsen anxiety-induced muscle twitches and spasms. This is because when you are dehydrated, your body is less able to transport nutrients to your muscles.

Inactivity and anxiety
While panic attacks are typically not life-threatening, they can be frightening experiences. People with panic disorder often experience uncomfortable physical symptoms, including sweating, accelerated heart rate, shaking, trembling, and tense muscles. Tense muscles are a common problem for people with panic disorder. Muscles become tense during a panic attack and can cause feelings of stiffness throughout the body long after the attack has passed.
During anxiety and panic attacks, the body experiences severe stress, and to respond to this stress, it uses up nutrients in the muscles and bones, such as magnesium, which may be necessary for proper nerve functioning. A lack of magnesium can also cause anxiety-induced stress, further impacting the nervous system and leading to involuntary muscle movements.
Anxiety can also cause muscle tension, which tires out the muscles and leads to spasms. Excess adrenaline produced during anxiety can also excite the nervous system, causing muscles to need to move. This can result in muscle twitches, which can occur anywhere in the body and last for seconds or hours.
Research has shown that physical inactivity is associated with increased levels of anxiety, depression, and stress. For example, during the COVID-19 pandemic, physical inactivity, alongside social isolation, contributed to higher levels of anxiety. Similarly, a study of chronic disease patients in Myanmar and Vietnam found a link between high sedentary behaviour and low physical activity with higher rates of anxiety and depression.
To counteract a sedentary lifestyle, it is recommended to schedule regular breaks to move, such as standing, stretching, or going for a short walk. Thirty minutes of exercise for 3 to 5 days a week can help improve anxiety symptoms.

Neurotransmitters and anxiety
Anxiety is a complex condition that involves the interaction of numerous brain pathways and neurotransmitters. While the exact mechanisms are not yet fully understood, research has identified several neurotransmitters that play a crucial role in the modulation of anxiety responses.
One of the key neurotransmitters involved in anxiety is gamma-aminobutyric acid (GABA), which has long been regarded as central to the regulation of anxiety. GABA is an inhibitory neurotransmitter, and its dysfunction is believed to underlie anxiety states. Drugs like benzodiazepines, which are commonly used to treat anxiety disorders, bind to GABA receptors and produce an anxiolytic effect. Additionally, the amygdala, which is involved in the fear response, contains inhibitory networks of GABAergic interneurons that play a role in modulating anxiety responses.
Another well-studied neurotransmitter in the context of anxiety is serotonin. Low levels of serotonin have been linked to both anxiety and depression. Certain medications can improve serotonin flow and reduce anxiety. Serotonin is one of the monoaminergic systems implicated in the pathogenesis of mood and anxiety disorders, along with norepinephrine and dopamine.
Other neurotransmitters that have been implicated in anxiety include opioid peptides, endocannabinoids, neuropeptide Y, oxytocin, and corticotropin-releasing hormone. These neurotransmitters interact with each other and are modulated by local and distant synaptic relays. While the specific roles of each neurotransmitter in anxiety are not yet fully understood, their dysfunction can contribute to the development of anxiety disorders.
Furthermore, hormones also play a significant role in anxiety. For example, thyroid hormone dysfunction can lead to severe anxiety and panic attacks. Additionally, stress hormones, such as cortisol, can be released during anxiety, contributing to physical symptoms like muscle contractions and involuntary movements.
