From cold drinks to fruit juice: 7 beverages to avoid with dinner if you want a good night sleep

A good night's sleep is not only about switching off your phone or sleeping early. What you drink in the evening also plays a big role. Many beverages that seem harmless can keep your body active, upset digestion, or trigger acid reflux, making it difficult to sleep well. Drinks loaded with caffeine, sugar, alcohol or carbonation may interfere with the body's natural process of winding down at night. Experts say choosing the right evening drink can support better sleep and help you wake up feeling more refreshed.

1. Coffee

Many people enjoy ending the day with a cup of coffee, but it may not be the best habit if you struggle with sleep. According to Healthline, caffeine acts as a central nervous system stimulant that increases alertness and can stay in the body for several hours.

Healthline also cites a 2013 study which found that consuming 400 mg of caffeine at bedtime, or even three to six hours before bed, significantly disrupted sleep. Participants took longer to fall asleep and slept for a shorter duration. Coffee may also increase stomach acid production, making heartburn and acid reflux worse, especially after dinner.

2. Energy drinks

Energy drinks are designed to keep people awake, which is exactly why they are a poor choice before bedtime. These beverages often contain high amounts of caffeine along with sugar and other stimulants.

Drinking them in the evening may delay sleep, increase heart rate, cause restlessness and even worsen acid reflux in some people. Even sugar-free versions may still contain enough caffeine to affect sleep quality.

3. Sugary soft drinks and soda

Soft drinks are another beverage experts recommend avoiding at night. Besides containing large amounts of added sugar, many sodas also have caffeine.

The combination can lead to blood sugar spikes followed by crashes, while carbonation may increase bloating and stomach discomfort after dinner. Research has also linked high sugar intake with more sleep interruptions during the night.

4. Strong black or green tea

Tea is often considered a lighter alternative to coffee, but black tea and many green teas still contain caffeine.

According to Healthline, caffeinated beverages, including tea, can negatively affect sleep by increasing alertness. Drinking strong tea close to bedtime may reduce sleep quality and make it harder to enter deep, restorative sleep. Herbal teas that are naturally caffeine-free are generally considered a better evening option.

5. Alcohol

Alcohol may make people feel sleepy at first, but experts say that does not mean it improves sleep.

Sleep specialists note that alcohol can reduce rapid eye movement (REM) sleep, increase night-time awakenings and make snoring or sleep apnoea worse. It may also increase the need to urinate during the night, breaking sleep repeatedly. In addition, alcohol can irritate the stomach lining and worsen acid reflux.

6. Packaged fruit juices

Fruit juice is often seen as a healthy choice, but packaged versions can contain large amounts of added sugar with very little fibre.

Without fibre to slow sugar absorption, blood sugar levels can rise quickly, which is not ideal before bedtime. Whole fruits are generally considered a healthier option because they provide fibre along with natural sugars.

7. Carbonated and acidic drinks

Carbonated beverages, including fizzy drinks and sparkling soft drinks, can trap gas in the digestive system, leading to bloating, burping and abdominal discomfort.

Experts also warn that acidic drinks such as orange juice may trigger acid reflux, especially in people with gastroesophageal reflux disease (GERD). According to the International Foundation for Gastrointestinal Disorders (IFFGD), many people with GERD experience symptoms after bedtime, and acidic beverages can make the problem worse by increasing stomach acid and relaxing the muscle that prevents acid from flowing back into the esophagus.

What should you drink instead?

Experts suggest choosing simple beverages that support both digestion and sleep. Plain water during the day, warm water, unsweetened herbal teas such as chamomile or ginger, warm milk if tolerated, and buttermilk in moderation are better evening choices. It is also helpful to finish dinner at least two to three hours before bed, avoid overeating, and limit late-night caffeine and sugary drinks.
