Restless Leg Syndrome: Symptoms, Causes, and Treatments
As a sleep specialist, trainer, or health coach, you know the importance of a good night’s sleep for overall health and wellbeing. However, what do you do when your clients complain of leg discomfort and the constant urge to move their legs, keeping them up at night? While this may seem like a minor annoyance, it could be a symptom of a larger issue: Restless Leg Syndrome (RLS).
Restless legs syndrome (RLS)—also known as Willis-Ekbom Disease affects millions of people worldwide and can have a significant impact on sleep quality, mood, and daily activities. RLS is a neurological disorder that is characterized by an irresistible urge to move the legs, particularly at night. WED is believed to be related to dysfunction in the dopamine system in the brain and is often treated with medications such as dopamine agonists.
In addition to the symptoms of RLS, people with WED may also experience involuntary leg movements during sleep, known as periodic limb movements of sleep (PLMS). PLMS can cause sleep disturbances, which can lead to daytime fatigue and decreased productivity.
The condition can have a significant impact on a person’s quality of life, causing sleep disturbances, daytime fatigue, and decreased productivity. This lesson will provide an overview of RLS, including its symptoms, causes, and treatments. As a fitness or health professional, it’s important to be aware of RLS and its symptoms, causes, and treatments, in order to provide your clients with the best care possible.
Symptoms of Restless Leg Syndrome
The primary symptom of RLS is an overwhelming urge to move the legs, which is often accompanied by uncomfortable sensations in the legs. These sensations are described as aching, throbbing, itching, or crawling, and are typically relieved by movement. Symptoms are often worse at night, which can lead to sleep disturbances and insomnia. People with RLS may also experience involuntary leg movements during sleep, known as periodic limb movements of sleep (PLMS).
Causes of Restless Leg Syndrome
The exact cause of RLS is unknown, but it is believed to be related to dysfunction in the dopamine system in the brain. Dopamine is a neurotransmitter that plays a role in movement, pleasure, and motivation, and is involved in the regulation of muscle activity. Dysfunction in the dopamine system can lead to an imbalance in the regulation of muscle activity, resulting in the symptoms of RLS.
One study found that people with RLS had higher levels of anxiety and depression than those without RLS (Bachhuber et al., 2010). Additionally, stress has been identified as a potential trigger for RLS symptoms in some individuals (Manconi et al., 2012). The stress response can cause changes in neurotransmitter levels, including dopamine, which may contribute to the development or exacerbation of RLS symptoms.
In some cases, RLS may also be related to other psychiatric conditions. For example, RLS has been associated with attention-deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD) (Ecker et al., 2010; Cho et al., 2017). In these cases, treating the underlying psychiatric condition may help alleviate RLS symptoms.
Psychological interventions such as cognitive-behavioral therapy (CBT) may also be helpful in managing RLS symptoms. CBT is a form of therapy that focuses on identifying and changing negative thoughts and behaviors that contribute to symptoms. One study found that CBT was effective in reducing RLS severity and improving sleep quality in people with RLS (Barker et al., 2006).
RLS can also be related to other medical conditions, such as iron deficiency anemia, peripheral neuropathy, kidney failure, and pregnancy. In some cases, RLS may be caused using certain medications, such as antidepressants, antihistamines, and antipsychotics.
Treatments for Restless Leg Syndrome
Treatment for RLS depends on the severity of symptoms and underlying causes. In some cases, lifestyle changes such as improving sleep hygiene and reducing caffeine intake can improve symptoms. Other treatments for RLS include medications and alternative therapies.
Medications
There are several medications that are used for treatment. Dopamine agonists, such as pramipexole and ropinirole, are commonly prescribed to increase dopamine levels in the brain and reduce RLS symptoms. Iron supplements may also be recommended if RLS is caused by iron deficiency anemia.
Benzodiazepines, such as clonazepam, are sometimes used to treat RLS because they have a sedative effect and can help with sleep. However, they can also be habit-forming and have side effects such as dizziness and confusion.
Alternative Therapies
Alternative therapies such as acupuncture, massage, and yoga may also be helpful for managing symptoms. These therapies can help reduce stress and promote relaxation, which can improve sleep quality and reduce symptoms. However, more research is needed to determine the effectiveness of these therapies.
Magnesium
There is some evidence to suggest that magnesium supplementation may be helpful in managing restless leg syndrome. Magnesium is an essential mineral that plays a role in numerous bodily functions, including muscle and nerve function. It is also involved in the regulation of neurotransmitters, including dopamine, which is believed to play a role in the development of RLS.
One study found that magnesium supplementation significantly reduced RLS symptoms in a group of older adults (Abbasi et al., 2017). The study participants received either 500 mg of magnesium or a placebo for 8 weeks. The group that received magnesium experienced a significant reduction in RLS symptoms, as well as improvements in sleep quality and mood.
Another study found that magnesium supplementation was effective in reducing RLS symptoms in pregnant women (Gontijo-de-Amaral et al., 2010). The study participants received either 400 mg of magnesium or a placebo for 4 weeks. The group that received magnesium experienced a significant reduction in RLS symptoms, as well as improvements in sleep quality and overall quality of life.
While these studies suggest that magnesium supplementation may be helpful in managing RLS symptoms, more research is needed to confirm these findings and determine the optimal dosage and duration of treatment. It is also important to note that while magnesium is generally considered safe, high doses can cause side effects such as diarrhea, nausea, and abdominal cramping. Individuals considering magnesium supplementation for RLS should consult with their healthcare provider to determine if it is safe and appropriate for their individual needs.

RLS During Pregnancy
RLS is a common condition during pregnancy, affecting up to 26% of women. Pregnancy-related RLS is thought to be caused by hormonal changes, iron deficiency, and increased pressure on the legs. Symptoms during pregnancy can be particularly troublesome because they can lead to sleep disturbances, which can increase the risk of complications during pregnancy.
Treatment for RLS during pregnancy may include iron supplements, massage, and exercise. Medications such as dopamine agonists and benzodiazepines should be used with caution during pregnancy, as they can have potential risks to the fetus.
Hot Feet and Restless Legs at Night
Hot feet and restless legs at night are common symptoms of RLS. Hot feet are described as a sensation of burning or heat in the feet, which can be relieved by movement. Restless legs at night are characterized by an irresistible urge to move the legs, particularly at night or during periods of rest. These symptoms can be particularly troublesome because they can lead to sleep disturbances and insomnia.

Sleep Hygiene Strategies for Managing Restless Leg Syndrome
Improving sleep hygiene can be an effective way to manage Restless Leg Syndrome symptoms. Sleep hygiene refers to the practices and habits that can promote good sleep, such as going to bed and waking up at the same time each day, avoiding caffeine and alcohol before bedtime, and creating a comfortable sleep environment.
Regular exercise can also improve sleep quality and reduce symptoms. Exercise can help reduce stress and promote relaxation, which can improve sleep quality and reduce symptoms of Restless Leg Syndrome. However, it is important to avoid exercising too close to bedtime, as this can have the opposite effect and make it harder to fall asleep.
In addition to lifestyle changes, there are several other treatments that can be effective for managing symptoms. For example, taking a warm bath or using a heating pad on the legs can help relieve discomfort and promote relaxation. Additionally, practicing mindfulness and relaxation techniques such as deep breathing and meditation can help reduce stress and improve sleep quality.
Overall, improving sleep hygiene can be an effective way to manage Restless Leg Syndrome symptoms. Practicing good sleep habits, such as going to bed and waking up at the same time each day, avoiding caffeine and alcohol before bedtime, and creating a comfortable sleep environment, can help reduce symptoms of RLS and improve overall quality of life.
