Muscle twitching, also known as fasciculation, is an involuntary contraction of the muscle fibres. It is usually not serious and often goes unnoticed. However, chronic muscle twitching can be a symptom of an underlying medical condition. Stress, including anxiety-induced stress, can cause muscle twitching by using up the body's energy faster than normal. This, coupled with factors such as sleep deprivation, stimulants, nutritional deficiencies, dehydration, medication, and hormone changes, can lead to chronic muscle twitching. Addressing these underlying causes can help alleviate muscle twitching symptoms.

What You'll Learn
Stress and anxiety
Muscle twitching is a common indication of anxiety and stress. It is a result of the brain sending signals to the muscles when the body is still and has no intention to move, causing involuntary body jerking. This is triggered by the release of stress hormones like adrenaline, which increases the likelihood of muscle twitching. Chronically elevated stress hormones can cause anxiety-like symptoms, including muscle twitching.
Anxiety-induced muscle twitches can occur alone or with other anxiety symptoms. They can be slow, sporadic, or intermittent, and can last for seconds or hours. They can affect any part of the body, such as the arms, legs, facial muscles, abdominal muscles, and neck. The twitches may come and go at any time, and trying to relax does not necessarily stop them.
To manage muscle twitching caused by stress and anxiety, one can try various relaxation techniques such as visualisation, mindfulness, meditation, yoga, and Tai Chi. Regular exercise, maintaining a healthy diet, and reducing caffeine intake can also help. It is important to consult a healthcare professional to ensure that the twitching is not caused by other underlying health conditions.

Nutritional deficiencies
Vitamin D deficiency can cause muscle twitching. Vitamin D helps the body absorb calcium, and a lack of it can lead to bone weakness, pain, and fractures. It can also cause muscle issues, including twitching and spasms. This can be treated by increasing your vitamin D intake through sun exposure or consuming vitamin D-rich foods such as fatty fish, egg yolks, mushrooms, and fortified foods.
Calcium deficiency, or hypocalcemia, can also cause muscle twitching. Calcium is essential for maintaining bone and muscle health. Low calcium levels can lead to muscle aches, twitches, and fatigue. You can increase your calcium intake by consuming dairy products, soy beans, tofu, leafy greens, and nuts.
Magnesium deficiency is another common cause of muscle twitching. Magnesium helps transport calcium across cell membranes and supports nerve and muscle health. Magnesium deficiency can be caused by a poor diet, excessive alcohol consumption, or diarrhea. Eating magnesium-rich foods, such as leafy greens, legumes, nuts, and seeds, can help prevent and treat this deficiency.
Vitamin B12 deficiency can also lead to muscle twitching. B vitamins support neurological health, and a B12 deficiency can cause cramps, spasms, tingling in the hands and feet, dizziness, and fatigue.
While nutritional deficiencies can cause muscle twitching, it is important to note that there are also other factors to consider, such as stress, anxiety, caffeine consumption, and dehydration. If you are experiencing persistent or concerning muscle twitching, it is always best to consult with a healthcare professional.

Dehydration
The body loses water through various processes, such as sweating, vomiting, and diarrhea. Certain activities, such as intense exercise, can also increase fluid loss. Additionally, the body's water needs can vary depending on individual factors such as the amount of physical activity and the climate one lives in.
Furthermore, dehydration has been linked to increased stress levels. When the body is dehydrated, cortisol levels, a primary stress hormone, tend to rise. This increase in cortisol can contribute to feelings of stress and anxiety. Stress itself is a common trigger for muscle twitching, so dehydration can indirectly lead to twitching by increasing stress.
To prevent dehydration and its associated issues, it is essential to maintain adequate fluid intake. Water is the best source of hydration, but other fluids and water-rich foods can also contribute to hydration. Monitoring urine color can be a simple way to assess hydration status; if the urine appears dark yellow, it is likely that the body needs more fluids. Staying hydrated helps maintain physical and mental well-being and can reduce the likelihood of muscle twitching caused by dehydration.

Sleep deprivation
Chronic stress can cause the nervous system to maintain a heightened state of arousal for extended periods, delaying the onset of sleep and causing anxious thoughts at night. This can lead to insomnia, which is characterised by difficulty falling asleep, staying asleep, or waking up too early. Insomnia can also be caused by other factors, such as medical conditions, sleep apnea, mood disorders, and chronic pain. It is important to note that insomnia can also contribute to or exacerbate mental health issues such as anxiety and depression.
Stress and sleep have a bidirectional relationship, meaning that insufficient sleep can cause further stress. Sleep deprivation can lead to negative moods, low energy, difficulty concentrating, and a general inability to function. It can also increase the risk of developing chronic health conditions, including heart disease, stroke, and depression.
To improve sleep quality, it is recommended to modify nighttime behaviours and create a relaxing bedtime routine. This may include practices such as mindfulness meditation, journaling, warm baths, yoga, and breathing exercises. Reducing screen time, caffeine intake, and light exposure in the bedroom can also improve sleep hygiene. For those with chronic insomnia or persistent daytime impairment, it is advised to seek professional help, such as cognitive behavioural therapy for insomnia (CBT-I).

Hormone changes
While muscle twitching is usually benign, it can be indicative of an underlying medical condition. Chronic stress is one of the factors that can cause muscle twitching. This is because stress induces the release of stress hormones, which can cause involuntary muscle movements.
Chronic stress can lead to elevated levels of stress hormones, such as adrenaline, which increases the likelihood of muscle twitching. The body's stress response, known as the "fight, flight, or freeze" reaction, results in physical changes as the body prepares for action. These changes include increased blood sugar, blood pressure, and electrical activity in the nervous system, as well as muscle tightening. The increase in blood sugar caused by stress can also lead to muscle twitching, especially when coupled with anxiety-induced malnutrition, which further decreases blood sugar levels.
Hormones affect the body in numerous ways, and a change in hormone levels can cause anxiety-like symptoms or aggravate existing anxiety disorders, including muscle twitching. For example, low levels of certain hormones can be interpreted by the brain as a deficiency, triggering stress and resulting in involuntary muscle spasms. Additionally, hormonal changes associated with life transitions, monthly menstrual cycles, or chronic stress can impact muscle twitching.
Stress and anxiety can also lead to dehydration, which affects muscle twitching. Dehydration impairs the body's ability to transport nutrients to the muscles, and sudden changes in electrolyte levels after rehydration can increase the risk of muscle cramps.
To alleviate muscle twitching caused by stress-induced hormone changes, reducing stress levels is crucial. This can be achieved through relaxation techniques such as meditation, yoga, or Tai Chi. Regular exercise, maintaining a healthy diet, and consulting a therapist can also help manage stress and its impact on hormone levels and muscle twitching.

Frequently asked questions
Muscle twitching, also known as body jerking, is when a singular muscle or group of muscles moves involuntarily. This can range from a small muscle movement to a more noticeable jerk.
Yes, stress can cause muscle twitching. Stress causes the brain to send signals to the muscles, resulting in involuntary movements. Furthermore, stress triggers the release of stress hormones like adrenaline, which increases the likelihood of muscle twitching.
Reducing stress can help alleviate muscle twitching. This can be achieved through relaxation techniques such as meditation, yoga, visualisation, mindfulness, and tai chi. Regular exercise, a healthy diet, and adequate sleep can also help reduce stress and, consequently, muscle twitching.
