Muscle spasms, also known as charley horses, are sudden, involuntary muscle contractions that can occur in any muscle in the body. They are very common and are usually not serious. However, they can sometimes be caused by or indicate underlying health or psychological conditions. Muscle spasms have been linked to various triggers and causes, including dehydration, overexercising, stress, anxiety, nerve disorders, thyroid problems, and certain medications. While muscle spasms typically resolve on their own, consulting a healthcare provider is recommended if they are severe, persistent, or accompanied by other symptoms.

What You'll Learn

Dehydration, diuretics, and electrolyte imbalance
Dehydration, the loss of body fluids, is a common cause of muscle spasms. When dehydrated, the body's electrolyte levels drop, disrupting nerve function and muscle contractions, and increasing the likelihood of muscle spasms. Electrolytes, such as sodium, magnesium, potassium, chloride, and calcium, are essential for proper muscle function. They help the body regulate fluids and maintain nerve and muscle function. For instance, potassium supports muscle contractions and magnesium aids in muscle relaxation. Dehydration can be caused by a variety of factors, including sweating, sickness, diarrhea, and vomiting.
Diuretics, or water pills, are medications that increase urination, leading to fluid loss. They are often prescribed for individuals with high blood pressure or heart disease. While diuretics can help manage these conditions, they can also contribute to dehydration and electrolyte imbalances. This is because diuretics increase the excretion of electrolytes, particularly potassium, through urine. As a result, diuretic use can be a factor in muscle spasms.
Electrolyte imbalances can occur due to a variety of reasons, including diet, sweating, urination, diarrhea, medication side effects, diuretic consumption, and absorption issues. When there is an imbalance of electrolytes, either too high or too low, it can negatively affect muscle function and lead to muscle spasms. Severe muscle cramps all over the body could indicate an electrolyte imbalance or a more serious underlying medical condition. Therefore, it is important to maintain adequate hydration and electrolyte levels to prevent and manage muscle spasms.

Stimulants, stress, and anxiety
While there is no definitive answer to whether thinking too much causes muscle spasms, stimulants, stress, and anxiety can all contribute to muscle spasms.
Stimulants
Stimulant medications, such as amphetamines, lisdexamfetamine, and dextroamphetamine-amphetamine, can cause muscle pain, cramping, stiffness, and twitching. These medications are often used to treat ADHD. Additionally, powerful stimulant drugs, such as cocaine, methamphetamine, ecstasy, spice, and inhalants, can damage the brain and compromise the functioning of the cardiovascular system, leading to movement problems and damage to the muscular system.
Stress
Stress can cause muscle tension, pain, and headaches. It can also lead to insomnia, which can further contribute to muscle spasms.
Anxiety
Anxiety is associated with muscle tension, which can lead to cramping and spasms. The excess adrenaline produced during anxiety can excite the nervous system, causing muscles to involuntarily contract and spasm. Additionally, people with anxiety are more prone to dehydration, which is a common trigger for muscle spasms. Furthermore, during anxiety attacks, the body uses up nutrients in the muscles and bones, such as magnesium, which may be necessary for proper nerve functioning, leading to muscle spasms.
While stimulants, stress, and anxiety can be factors in muscle spasms, it is important to note that muscle spasms can be caused by various factors, including dehydration, electrolyte imbalance, vitamin or mineral deficiencies, and certain medications.

Medication, supplements, and health conditions
While there is no clear indication that thinking too much causes muscle spasms, there are several medications, supplements, and health conditions that can contribute to this issue.
Medication
Certain medications can cause muscle spasms or twitches. For instance, water pills (diuretics) can lower potassium levels in the body, leading to muscle spasms. Some antidepressants, epilepsy drugs, and psychosis medications may also cause muscle twitches. Additionally, specific drug groups, such as hypolipemic drugs, beta-blockers, glucocorticosteroids, and antimalarials, have been associated with drug-induced myopathies, which can result in muscle pain and side effects.
Supplements
Magnesium supplements are commonly used to treat leg cramps, but their effectiveness is not strongly supported by research. While magnesium is safe and affordable, the relationship between magnesium and other nutrients like calcium and potassium influences muscle cramping. Therefore, addressing any deficiencies in these nutrients may be more effective in reducing muscle spasms.
Health Conditions
Muscle spasms can be a symptom of an underlying health condition. In some cases, they may indicate a neurological issue, such as dystonia, which results in involuntary muscle movements. Chronic muscle cramps, accompanied by symptoms like pain, muscle weakness, or poor coordination, could signal a neurological condition affecting the brain's ability to control muscles. Additionally, kidney problems can lead to muscle cramps and spasms as a late symptom.

Exercise, fatigue, and tension
Exercise
Exercising can be a cause of muscle spasms, especially when certain factors are not considered. Overexercising or engaging in too much high-intensity exercise without proper warm-up can lead to muscle spasms. Exercising in extreme heat or on concrete floors can also increase the likelihood of muscle spasms. Not drinking enough water before exercise can contribute to dehydration, which is another common trigger for muscle spasms.
Fatigue
Fatigue is a common symptom associated with muscle spasms and can be caused by various factors, including overtraining or overexercising. Overtraining syndrome occurs when an individual exercises too frequently, intensely, or beyond their body's ability to recover. This can lead to physical symptoms such as muscle pain and stiffness, as well as mental and emotional symptoms like mood changes, irritability, and fatigue. The intensity, endurance, and type of exercise can all influence the body's energy depletion and subsequent sensations of fatigue.
Tension
Tension, often related to stress or anxiety, can be a contributing factor to muscle spasms. Stress and anxiety can lead to muscle twitches, particularly in the face, and can cause tension and pain in the muscles. Relaxation techniques, such as massage or meditation, can help alleviate tension and prevent muscle spasms triggered by stress.

Psychological conditions and disorders
While muscle spasms can be caused by a variety of factors, including dehydration, mineral deficiencies, and certain medications, there is also a link between psychological conditions and muscle spasms.
Psychogenic movement is an unwanted muscle movement, such as a spasm or tremor, that is caused by an underlying psychological condition. This can involve any part of the body and may resemble muscle movements associated with biological conditions or structural abnormalities. Psychogenic movement is often involuntary and can develop as a part of various disorders.
Conversion Disorder
Psychogenic movement is commonly associated with conversion disorder, where a psychological event causes physical symptoms with no known medical cause. This can include psychogenic tremor, which involves sudden onset and remission, and increased incidence with stress. It can also lead to psychogenic dystonia, resulting in involuntary muscle contractions that cause slow, repetitive movements or abnormal postures that may be painful.
Somatoform Disorder
Somatoform disorder is another condition that can lead to psychogenic movement. It is characterized by multiple-system symptoms associated with distress and/or dysfunction. The psychological distress results in physical symptoms, including muscle spasms.
Factitious Disorder
Factitious disorder is an illness that simulates symptoms for psychological reasons. It is not characterized as a psychiatric disorder, but individuals may pretend to have an illness to achieve secondary goals, such as obtaining drugs or disability benefits. In this case, the muscle spasms are feigned rather than genuine physiological responses.
Stiff Person Syndrome (SPS)
Stiff Person Syndrome (SPS) is a rare autoimmune neurological disorder that causes muscle stiffness and painful spasms. SPS can cause episodes of muscles locking up and becoming extremely stiff, and the spasms can worsen with emotional stress. While there is no cure, treatments are available to manage symptoms and improve quality of life.
While psychological conditions can contribute to muscle spasms, it is important to note that muscle spasms can also be caused by various physiological factors. If you are experiencing persistent or severe muscle spasms, it is advisable to consult a healthcare professional for a comprehensive evaluation.
