Quick take Heartburn has a habit of arriving just as your head hits the pillow. Here is why lying down makes it worse, which evening changes are worth trying, and the signs that mean a GP should take a look.
What this answer covers
4 min · Oct 4, 2026Few things spoil a night quite like that familiar burn rising behind the breastbone just as you settle down. Heartburn is common, and for most people it comes and goes with meals, stress or the odd late takeaway. But when it keeps turning up at bedtime, it can chip away at sleep and leave you dreading the evening.
This answer explains why night-time is often the worst time, the everyday changes that many people find helpful, and when it is time to stop managing it alone.
Why heartburn often gets worse when you lie down
At the top of the stomach sits a ring of muscle that is meant to keep stomach contents where they belong. When it relaxes at the wrong moment, acid can travel back up into the food pipe and cause that burning feeling. During the day, gravity is on your side. Once you lie flat, it no longer helps, and a full stomach pressing against that muscle makes leaks more likely.
Evenings also tend to be when we eat the largest meal, have a drink or two and then sit slumped on the sofa before heading to bed. Put together, that is a fairly reliable recipe for night-time symptoms.
Evening habits worth changing first
- Leave a gap between dinner and bed. Giving your stomach a few hours to empty before you lie down is one of the most commonly suggested changes.
- Make the last meal smaller. Moving more of your eating to earlier in the day can ease the load at night.
- Notice your own triggers. Rich, fatty or spicy dishes, chocolate, coffee, fizzy drinks, citrus and alcohol bother some people and not others. A short food note helps you spot yours rather than cutting out everything.
- Loosen up. Tight waistbands and belts squeeze the stomach. Comfortable clothes in the evening can make a surprising difference.
- Stay upright after eating. A gentle stroll or sitting up straight is kinder than lying across the sofa.
- Think about smoking. Smoking is linked with reflux, and stopping helps in many ways beyond the stomach.
Position and the bed itself
How you lie can matter as much as what you ate. Many people find these adjustments helpful:
- Raise the head end of the bed. Blocks under the bed legs or a wedge under the mattress lift the whole upper body. Piling up pillows tends to bend you at the waist instead, which can make things worse.
- Try lying on your left side. Many people with reflux report that their left side is more comfortable than their right.
- Keep your weight in mind gently. Extra weight around the middle presses on the stomach. Small, steady changes are more realistic than crash diets.
What about remedies from the pharmacy?
There are several kinds of heartburn remedies available over the counter, and they work in different ways. Some neutralise acid for quick relief, others form a protective layer, and some reduce how much acid the stomach makes. A pharmacist is the best person to ask which suits you, especially if you take other medicines, are pregnant or have other health conditions. Always follow the pack instructions or the advice you are given.
Longer-term acid-reducing medicines are widely used, and like any medicine they have pros and cons that are worth discussing with a professional. Our earlier article on Nexium as a common heartburn treatment looks at that side of the subject in more detail.
A simple evening plan to try
| Time | What to do |
|---|---|
| Early evening | Eat a moderate dinner and go easy on your known triggers |
| After dinner | Stay upright, take a short walk or tidy the kitchen |
| Before bed | Skip late snacks and alcohol, change into loose clothes |
| In bed | Head end raised, try your left side, note how the night went |
Give the changes a couple of weeks before deciding whether they help. One good or bad night says very little.
When to see a GP
Occasional heartburn is common. Please see a GP if it happens most days, keeps waking you, or does not settle with the changes above and pharmacy advice. Book sooner if you notice any of the following:
- difficulty or pain when swallowing, or food feeling stuck;
- losing weight without trying, or being sick repeatedly;
- being sick with blood, or very dark, tarry stools;
- heartburn that has started for the first time later in life and keeps coming back.
Chest pain is not always heartburn. If pain spreads to the arm, jaw, neck or back, or comes with breathlessness, sweating or feeling faint, call emergency services straight away rather than waiting to see if it passes.
A GP may suggest further tests or refer you to a specialist when symptoms are persistent. Our answer on seeing a gastroenterologist for long-running digestive problems explains what that step usually involves.
