Restless Legs Syndrome (RLS): What It Is and How It Affects Sleep

Although many people dismiss it as a minor annoyance, Restless Legs Syndrome can significantly disrupt sleep, making it difficult to fall asleep, stay asleep, and feel rested the next day. Left untreated, it can affect your energy, mood, work performance, and overall quality of life.

At Athens Sleep and Wellness Center, we help patients identify sleep disorders like Restless Legs Syndrome and develop personalized treatment plans that improve sleep quality and overall well-being.

What Is Restless Legs Syndrome?

Restless Legs Syndrome is a neurological condition characterized by an irresistible urge to move the legs, usually accompanied by uncomfortable sensations.

People often describe these sensations as:

• Crawling
• Tingling
• Pulling
• Aching
• Itching
• Throbbing
• Electric-like sensations

These symptoms typically occur during periods of rest, particularly in the evening or at night, and are temporarily relieved by movement.

According to the National Institute of Neurological Disorders and Stroke, Restless Legs Syndrome affects millions of adults and can interfere significantly with sleep and daily functioning.

Why Does RLS Affect Sleep?

Most people experience symptoms when they are sitting quietly, lying down, or trying to fall asleep. As soon as they become comfortable, the uncomfortable sensations begin.

Walking, stretching, or moving the legs often provides temporary relief, but the symptoms usually return once movement stops. This cycle can repeat throughout the evening, making it difficult to fall asleep and causing frequent awakenings during the night.

Many people with RLS wake up feeling unrefreshed despite spending enough time in bed.

Common Symptoms of Restless Legs Syndrome

Symptoms vary from person to person but commonly include:

• An overwhelming urge to move the legs
• Uncomfortable sensations deep within the legs
• Symptoms that worsen during rest
• Temporary relief with movement
• Symptoms that become more noticeable in the evening or at night
• Difficulty falling asleep
• Frequent nighttime awakenings
• Daytime fatigue

Although the legs are most commonly affected, some people experience similar symptoms in their arms.

What Causes Restless Legs Syndrome?

The exact cause is not always known, but researchers believe RLS is related to changes in how the brain regulates movement. Several factors may increase the risk, including:

Iron Deficiency

Low iron levels are one of the most common treatable causes of Restless Legs Syndrome. Even people without anemia may have low iron stores that contribute to symptoms.

Family History

RLS often runs in families, particularly when symptoms begin before age 40.

Pregnancy

Some women develop Restless Legs Syndrome during pregnancy, especially during the third trimester. Symptoms often improve after delivery.

Chronic Medical Conditions

Certain health conditions are associated with a higher risk of RLS, including:

• Chronic kidney disease
• Diabetes
• Peripheral neuropathy
• Parkinson's disease

Certain Medications

Some medications may worsen Restless Legs Syndrome symptoms. Examples include certain antihistamines, antidepressants, and medications used to treat nausea. Your healthcare provider can determine whether medications may be contributing to your symptoms.

How Is Restless Legs Syndrome Diagnosed?

There is no single test that confirms Restless Legs Syndrome. Diagnosis is based primarily on your symptoms, medical history, and physical examination.

Your sleep specialist may ask:

• When do your symptoms occur?
• Do they improve with movement?
• Do they interfere with sleep?
• Is there a family history of RLS?
• Are you taking any medications?
• Do you have any chronic medical conditions?

Blood tests may also be recommended to evaluate iron levels and rule out other medical conditions.

Could It Be Something Else?

Several conditions can cause symptoms similar to Restless Legs Syndrome. These include:

• Muscle cramps
• Peripheral neuropathy
• Arthritis
• Poor circulation
• Leg muscle strain

A comprehensive evaluation helps determine the correct diagnosis and appropriate treatment.

Treatment Options for Restless Legs Syndrome

Treatment depends on the severity of your symptoms and whether an underlying cause is identified.

Lifestyle Changes

Simple changes may help reduce symptoms, including:

• Maintaining a consistent sleep schedule
• Exercising regularly, but avoiding intense activity close to bedtime
• Limiting caffeine and alcohol
• Avoiding nicotine
• Stretching before bed

Treating Underlying Conditions

Correcting iron deficiency or managing chronic medical conditions may significantly improve symptoms.

Medication

For moderate to severe Restless Legs Syndrome, prescription medications may be recommended to help reduce symptoms and improve sleep. Your healthcare provider will determine which treatment is most appropriate based on your medical history and symptom severity.

Why Early Evaluation Matters

Many people live with Restless Legs Syndrome for years before seeking medical care. Unfortunately, untreated RLS can lead to:

• Chronic sleep deprivation
• Daytime fatigue
• Difficulty concentrating
• Mood changes
• Reduced work performance
• Lower overall quality of life

Early diagnosis allows treatment to begin before sleep disruption significantly affects your health.
