Restless Legs Syndrome (RLS), also known as Willis-Ekbom disease, is a nervous system disorder characterized by an irresistible urge to move the legs, especially during rest. Many people with RLS have trouble falling and/or staying asleep.  

RLS affects 5-10% of American adults and 2-4% of children. While RLS can impact individuals of all ages, it tends to be more severe in older adults.  

## Restless Leg Symptoms

 Symptoms can range from mild to severe, which may be intolerable.  Symptoms of RLS include, but are not limited to:

- An irresistible urge to move the legs due to uncomfortable sensations.
- Worsening of the sensations during periods of rest.
- Temporary relief from discomfort when the legs are moved.
- Evening and nighttime leg twitching or jerking.

These symptoms can feel like:

- Itchiness
- Crawling
- Throbbing
- Pins and needles

## What Causes Restless Legs Syndrome?

 Iron deficiency is one of the main causes of RLS, however, other factors can contribute to RLS, like: 

- Genetics
- Underlying medical conditions
- Medications

## Restless Leg Syndrome Triggers

 Several things can make RLS symptoms worse.  Some triggers include:

- Caffeine
- Alcohol
- Tobacco
- Certain medications 

Temperature can also impact RLS.  While hot, humid weather can worsen symptoms for some – others might have issues with the cold.  

## RLS Treatments

 There is no known cure for RLS, however, there are a variety of treatments that may help including: 

- Leg massages
- Hot baths
- Ice packs
- Regular exercise
- Prescription medications

While practicing [good sleep habits](https://www.kentri.org/blog/sleep-hygiene-tips) may not resolve your RLS symptoms, it can offset the sleep you have lost due to this condition.
