Pregnancy & Sleep: Why It’s Hard to Rest — and How to Support Your Body

Nov 28 / Sol Alonso
Sleep during pregnancy can feel unpredictable. Some nights you fall asleep easily but wake up several times; other nights your mind stays alert even when your body is exhausted. If you’ve been struggling with insomnia or broken sleep, you're not alone — it’s one of the most common experiences during pregnancy.

In this note, I’ll walk you through why sleep becomes more difficult, what your body is communicating, and how you can support yourself with gentle, somatic practices.

Why Sleeping Well Becomes More Challenging in Pregnancy

  • 1. Hormonal changes influence your sleep cycle

    Progesterone increases significantly during pregnancy. It helps maintain the pregnancy, but it also relaxes smooth muscle tissue — including the digestive tract — which can lead to indigestion, reflux and discomfort that make sleep more fragmented.
     Melatonin production can also shift, altering your natural rhythm of alertness and rest.
    As hormones fluctuate, your internal sense of “day” and “night” becomes less predictable.


  • 2. Your nervous system is more sensitive

    Pregnancy heightens your sensory awareness. Your body becomes more reactive to small changes in temperature, noises, light and even your own thoughts.
    This is not a flaw — it’s a biological adaptation to protect you and your baby.
     But it also means your nervous system may take longer to settle at night.


  • 3. Physical discomfort increases as your body expands

    As the uterus grows, pressure on the diaphragm, bladder and lumbar spine increases. This can result in:

    - Frequent night-time waking to pee.
    - Difficulty finding a comfortable sleeping position.
    - Tightness in the ribs and upper back.
    - Sciatica or pelvic pressure

    Your body is working hard. Sleep is affected simply because everything is changing.


  • 4. Mental load and anticipatory thoughts

    Preparing for birth, imagining motherhood, navigating work or family demands, researching, planning, organising…

    Your mind may feel busy, even when your body is tired.
    This cognitive load can keep the system “on”, making it harder to unwind at night.


How Prenatal Yoga Supports Better Sleep

Prenatal yoga is one of the most effective non-pharmacological tools for sleep during pregnancy because it works on three levels at once:

  • 1. Physical relief

    Gentle movements free the diaphragm, ribs, shoulders and lower back — the areas that most often disturb comfort at night.

    When the breath can expand more easily, your whole system relaxes.


  • 2. Nervous system regulation

    Slow breathing, grounding postures and gentle transitions shift the body toward the parasympathetic state — the “rest and restore” mode required for sleep.


  • 3. Emotional decompression

    When you create space to breathe and connect with your body, the mental noise quiets down.
     
    You soften the inner dialogue and return to a sense of safety.


This is often the missing piece when insomnia is driven by stress or anticipatory anxiety.

Additional Tips to Support Sleep Naturally

  • Create a gentle evening routine
    Your body benefits from predictable rhythms.
    Try dimming the lights, slowing your pace and avoiding screens at least 45 minutes before bed.

  • Eat light in the evening
    Heavy meals increase reflux, which often worsens at night.
    Opt for warm soups, vegetables, or something easy to digest.

  • Support your body with pillows
    Place a pillow between your knees, one behind your back, and (if needed) one under the belly.
    Comfort supports deeper rest.

  • Let your exhale be longer than your inhale
    This simple breathing pattern signals to your nervous system: you’re safe, you can rest.

Mini Somatic Exercise: “Rocking the Breath Back Home”

This practice is designed to calm the mind, regulate your breath and soften tension before sleep.
  • Lie on your left side with a pillow between your legs.
  • Place one hand on your lower ribs and the other gently on the side of your head.
  • Inhale softly through the nose, feeling your ribs expand into your hand.
  • Exhale—and imagine your whole body melting into the bed.
  • Begin a small, rhythmic rocking: the slightest forward–back movement of the ribs, as if you were soothing yourself.
  • Repeat for 2–3 minutes, letting the breath guide the movement.
This helps down-regulate the nervous system, release rib tension and signal safety to your whole body.
