Acid Reflux at Night? Try These Simple Sleep-Saving Fixes
There’s nothing worse than lying down after a long day, hoping to finally relax — and suddenly feeling that telltale burn crawling up your throat. Nighttime acid reflux is a sleep wrecker. I’ve lost count of the number of times I’ve sat up in bed with a sour taste in my mouth, wondering if I should grab an antacid or try to sleep sitting up.
If that sounds familiar, you’re far from alone. Acid reflux at night is extremely common and often more intense than during the day. But the good news is, there are some incredibly practical, low-effort fixes that actually make a big difference. Let’s break them down.
Why Acid Reflux Feels Worse When You’re Sleeping
When you lie flat, gravity no longer helps keep stomach acid in your stomach — and that’s when reflux strikes. The lower esophageal sphincter (LES), a small valve that prevents acid from escaping the stomach, can relax or become weak. Add a full belly or a trigger food, and you’ve got the perfect storm for heartburn and sleep disruption.
According to the Sleep Foundation, nighttime acid reflux doesn’t just ruin sleep — it increases the risk of more serious issues, like respiratory irritation, chronic cough, and even dental erosion.
Simple Evening Habits to Help Prevent Reflux
Most people focus on medication, but your evening routine plays a huge role in acid production and symptom intensity. These basic lifestyle tips made the biggest difference for me:
- Finish dinner at least 3 hours before bed. This gives your stomach time to empty before lying down.
- Eat smaller, lighter meals in the evening. Avoid high-fat, spicy, or fried foods — they’re notorious for triggering reflux.
- Stay upright after eating. A short walk or some light tidying can help digestion and reduce pressure on your LES.
One of my go-to tricks? Swapping out acidic or greasy snacks for a banana or a rice cake with a little almond butter. For more gentle options, these reflux-friendly smoothies are surprisingly satisfying and easy to prep at night.
Best Sleep Positions for Reflux Prevention
Your sleep posture can make or break your night when dealing with reflux. I never realized how big an impact this had until I started sleeping slightly elevated and on my left side — it was like flipping a switch.
Try these positioning techniques:
- Use a wedge pillow or elevate the bed head: Raising your upper body 6–8 inches reduces the chance of acid flowing up.
- Sleep on your left side: This position keeps your stomach lower than your esophagus, naturally reducing pressure.
- Avoid sleeping flat or on your right side: These positions can aggravate symptoms and increase reflux episodes.

Helpful Natural Fixes to Support Better Sleep
While medication can help, I also found relief by incorporating a few natural options into my nightly wind-down. Here’s what worked:
- Warm chamomile or ginger tea: Calms the digestive system without caffeine or acidity.
- Melatonin: A sleep supplement that may also help tighten the LES. See the full explanation in this melatonin GERD guide.
- Chewing sugar-free gum after dinner: Increases saliva and promotes swallowing, which can help clear acid from the esophagus.
What’s key is finding what fits your body and sleep style. Some people do well with herbal supplements, while others just need consistent eating and sleeping habits to find relief.
When Nighttime Reflux Needs Medical Support
Sometimes, lifestyle changes alone aren’t enough — and that’s okay. If your reflux is waking you multiple times per night or you’re relying heavily on over-the-counter meds, it’s time to consult a doctor.
You should get evaluated if you experience:
- Persistent acid reflux more than twice a week
- Difficulty swallowing or unexplained weight loss
- Chronic coughing, hoarseness, or breathing issues during sleep
Your provider may recommend medications like PPIs or H2 blockers, or even order a sleep study if other issues like apnea are suspected. For a list of both lifestyle and prescription treatment options, this GERD treatment guide covers it all in plain English.
Restful Nights Are Possible — One Change at a Time
It took me a while to believe it, but restful sleep with acid reflux really is possible. You don’t have to overhaul everything overnight — even just changing your dinner time or switching to left-side sleeping can lead to better rest.
