> Restless Legs Syndrome (RLS) often becomes more noticeable and can significantly impact sleep quality during the third trimester, as your body prepares for birth.

It's common for many pregnant individuals to experience the urge to move their legs, often accompanied by uncomfortable sensations, as pregnancy progresses. While some may notice it earlier, the third trimester is when Restless Legs Syndrome (RLS) tends to peak, potentially disrupting your much-needed rest as you near your due date.

## Why it shows up this trimester

As your pregnancy reaches its final weeks, several factors can contribute to the heightened experience of RLS. Your blood volume is at its highest, and the growing uterus can put increased pressure on nerves and blood vessels in your pelvis and legs, potentially affecting circulation. Hormonal shifts, particularly in estrogen, continue to play a role. Additionally, evidence suggests that deficiencies in iron, folate, and magnesium can exacerbate RLS symptoms, and these can be more pronounced as your body works hard to support your growing baby in the third trimester.

## What it tends to feel like now

In the third trimester, the sensations of RLS might feel more intense and frequent, often appearing in the evenings or when you're trying to relax or sleep. You might describe it as an irresistible urge to move your legs, accompanied by crawling, tingling, aching, or even electric-like feelings deep within your calves or thighs. This can make it incredibly challenging to settle down for the night, leading to fragmented sleep and increased fatigue – something you're likely already navigating in late pregnancy. The discomfort can be quite frustrating when all you want is peaceful rest.

## What helps in this window

Finding comfort in the third trimester is key. Gentle movement, like a short walk or some prenatal yoga stretches before bed, can sometimes offer temporary relief. Focusing on good hydration throughout the day and ensuring your diet includes iron-rich foods, along with magnesium and folate, can be supportive. Many parents find warm baths or showers, leg massages, or applying a warm compress to their legs helpful. Some also explore magnesium supplements, but it's always wise to discuss any supplements with your care provider first to ensure they're right for you. Creating a calm, cool, and dark sleep environment can also set the stage for better rest, even if RLS is present.

## Working with your care team

If RLS symptoms are significantly impacting your sleep or causing distress, having a conversation with your OB or midwife is a valuable step. They can help rule out any underlying conditions, check your iron levels, and discuss safe and effective strategies for managing your symptoms. Remember, your provider is your best resource for your specific situation, and they can offer personalized guidance to help you navigate this common third-trimester experience with more ease and clarity.
