Your late-night food habits could be ruining your sleep, but these expert-recommended foods may help

There was a time when sleep came naturally. Lights dimmed, homes quietened, and the body followed the rhythm of the day. Today, that rhythm has fractured.

Urban Indians are sleeping less than ever. Long work hours, endless scrolling, late-night meals, stress about careers and finances, and constant stimulation from screens have slowly changed how the brain understands “night time.” Many people now go to bed exhausted but remain mentally alert for hours.

A study by the NIH has repeatedly highlighted how poor sleep is increasingly linked with obesity, diabetes, heart disease and declining mental health. The US Centers for Disease Control and Prevention (CDC) also notes that adults who sleep less than seven hours regularly face higher risks of chronic illnesses.

Dr Sourabh Pahuja, Senior Consultant, Sleep Medicine, Amrita Hospital, Faridabad says, “Certain foods can help the body fall asleep and stay asleep naturally by influencing hormones like melatonin and serotonin.”

He further explains, “Sleep is so tied to metabolism, gut health, stress hormones, nutritional balance. Some foods have compounds that can possibly help calm the nervous system and support the body’s internal sleep clock.”

One of the most researched foods for sleep is kiwi. Small clinical studies have shown that people who consumed two kiwis before bedtime experienced better sleep quality, longer sleep duration and fewer interruptions during the night. Researchers believe this may be linked to serotonin and antioxidant content.

A sleep-related nutrition study published by the US National Library of Medicine also discusses how foods rich in melatonin, magnesium and tryptophan may positively affect sleep quality.

Then come nuts, especially almonds and walnuts. These are rich in magnesium, a mineral closely associated with muscle relaxation and nervous system regulation. Walnuts also contain small amounts of melatonin, the hormone that helps regulate the sleep-wake cycle.

These foods do not act like sleeping pills. Their role is much gentler. They help create the internal conditions that allow the body to transition into sleep more naturally.

That difference matters. Modern sleep struggles are often less about the inability to sleep and more about the inability to slow down.

There is a reason warm milk before bed has survived across generations. Science now suggests many traditional bedtime foods may have biological value.

Bananas contain potassium and magnesium, both linked to muscle relaxation. Oats contain complex carbohydrates that may help the brain absorb tryptophan more efficiently. Pumpkin seeds are rich in magnesium and zinc, nutrients involved in nervous system health.

Warm milk contains tryptophan, an amino acid connected to serotonin production. Serotonin helps the body eventually produce melatonin.

Even simple evening meals can influence sleep more than people realise. Heavy oily dinners, spicy late-night snacks and excessive caffeine can keep the digestive system overstimulated long after bedtime.

Sleep experts say the body prefers consistency. Eating lighter dinners at regular hours may support better hormonal balance overnight.

Researchers are now paying closer attention to the relationship between gut health and sleep.

The gut and brain communicate constantly through hormones, nerves and immune signals. Diets rich in fruits, vegetables, legumes and fibre appear to support healthier gut bacteria, which may indirectly influence mood, stress levels and sleep quality.

This may partly explain why highly processed diets often leave people feeling sluggish during the day but restless at night.

Experts say sleep is not controlled by one organ alone. It reflects the condition of the entire body.

Food can support sleep, but it cannot replace treatment
Doctors caution against treating food as a cure for chronic insomnia.

Dr Pahuja warns, “There is no food that can cure chronic insomnia. Persistent sleep problems, loud snoring, excessive daytime sleepiness or frequent awakenings may be signs of an underlying sleep disorder that needs to be evaluated.”

That warning is important because many sleep disorders remain undiagnosed for years. Conditions like sleep apnea, anxiety disorders, hormonal imbalance and depression often first appear as disturbed sleep.

Sleep specialists also advise avoiding alcohol close to bedtime. While alcohol may initially make people feel sleepy, research shows it can disrupt deeper stages of restorative sleep later in the night.

The goal is not perfection. A peaceful night’s sleep is often built slowly through small habits, dimmer lights, calmer evenings, lighter dinners, fewer screens and foods that nourish rather than overstimulate the body.

Sometimes, the body simply needs permission to rest again.
