How Nutrition Affects Sleep

How Nutrition Affects Your Sleep?

What if someone told you that the food you eat is affecting how you sleep? Yes, the relationship between food and sleep is intricate and a significant one. 

Sleep is a foundational component affecting one's physical, mental, and emotional well-being. Simultaneously, the food we consume serves as the body's fuel, providing the necessary nutrients and energy for its functions. Therefore, understanding the relationship between food and sleep not only sheds light on the intricate workings of our body but also offers practical insights into how we can improve the quality of our rest. Let’s take a look at the scientific nuances between food and sleep to help you live a more balanced, healthy and rejuvenated life.

The Link Between Diet and Sleep Quality

Our dietary choices significantly impact sleep patterns and sleep-related functions. Certain foods contain compounds like tryptophan, a precursor to sleep-regulating hormones like melatonin, aiding in a more restful sleep. 

Further the link between food and sleep also relies on the balance of carbohydrates, proteins, and fats in our diet affects blood sugar levels, preventing one from waking up during the night time caused by fluctuations in glucose. Caffeine, (commonly found in coffee and tea), acts as a stimulant, which interrupts the ability to fall asleep, especially if consumed too close to bedtime.

Heavy or spicy meals cause digestive discomfort which interferes with relaxation, making it difficult to sleep. 

Staying hydrated is essential, as dehydration can lead to dry mouth and nasal passages, increasing the likelihood of snoring and sleep disruptions. 

The Role of Macronutrients in the Link between Food and Sleep



Carbohydrates are the body's primary energy source, providing fuel for various bodily functions, including brain activity and physical activities. There are two types of carbohydrates: simple carbohydrates (sugars) and complex carbohydrates (starches and fibre). Complex carbohydrates, found in whole grains, fruits, vegetables, and legumes, offer sustained energy release and prevent rapid spikes and crashes in blood sugar levels. The consumption of complex carbohydrates promotes the absorption of tryptophan, enhancing the production of serotonin and melatonin. This process is crucial for regulating mood, promoting relaxation, and ensuring a smoother transition into restful sleep.



Proteins are the building blocks of life, essential for the growth, repair, and maintenance of body tissues. They are composed of amino acids, each serving specific functions. Tryptophan, an amino acid found in proteins, is a precursor to serotonin and melatonin, neurotransmitters that regulate mood and sleep-wake cycles. Including protein-rich sources like lean meats, fish, eggs, dairy products, legumes, and nuts in our diet not only aids in the production of sleep-inducing hormones but also supports muscle development and repair, vital for overall health and physical performance.

Dietary fats are essential for nutrient absorption, brain health, and hormone regulation. They are categorised into saturated fats (found in animal products and some plant oils), unsaturated fats (monounsaturated and polyunsaturated fats, found in olive oil, avocados, and fatty fish), and trans fats (artificial fats found in processed foods). Healthy fats, particularly omega-3 fatty acids found in fatty fish like salmon, flaxseeds, and walnuts, have anti-inflammatory properties and support cardiovascular health. Moreover, fats play a crucial role in satiety, keeping us feeling full and satisfied after meals. Including moderate amounts of healthy fats in the diet is essential for maintaining energy levels, supporting brain function, and ensuring overall well-being.

Foods that Promote Sleep 

While overall food habits impact the sleep cycle and quality of sleep, here are some foods that are known for their sleep-promoting properties. Most of these foods are a natural source of Melatonin, the body’s sleep-wake cycle regulating hormones and incorporating these foods into your diet can help improve your sleep quality. You can learn more about melatonin uses, to better understand the benefits of these foods.

1. Cherries

Cherries, especially tart cherries, are a natural source of melatonin. Consuming cherries or cherry juice can help enhance sleep quality.

2. Bananas

Bananas contain both potassium and magnesium, which act as muscle relaxants. They also contain tryptophan, a precursor to melatonin and serotonin, aiding in relaxation and sleep.

3. Nuts

Certain nuts, such as almonds, walnuts, and pistachios, are good sources of magnesium. Magnesium plays a role in muscle relaxation and may help you unwind before bedtime.

4. Warm Milk

Warm milk has been associated with bedtime relaxation for centuries. It contains both tryptophan and calcium, promoting the production of melatonin.

5. Leafy Greens

Vegetables like spinach and kale are high in calcium, which helps the brain use tryptophan to produce melatonin. They also contain a range of nutrients that support overall health and well-being, contributing to better sleep.

6. Herbal Teas

Herbal teas like chamomile, valerian, and lavender have calming properties that can aid in relaxation and improve sleep. Their mild sedative effects make them very effective to help you fall asleep.

7. Whole Grains

Whole grains, such as brown rice and oats, have a high glycemic index. When consumed a few hours before bedtime, they can promote the production of tryptophan and serotonin, helping you relax and prepare for sleep.

8. Honey

Honey contains glucose, which signals the brain to shut off orexin, a neurotransmitter that controls alertness. Adding a small amount of honey to warm milk or herbal tea can promote relaxation and aid in falling asleep.

Foods to Avoid Before Bedtime

No what we know how food and sleep are interlinked and the food that we consume can affect your sleep cycle here's a list of thing you should definitely to steer clear of in the hours leading up to your bedtime: 

1. Caffeine

Coffee, tea, soft drinks, and even chocolate contain caffeine, a stimulant that can interfere with your ability to fall asleep. It's advisable to avoid these beverages at least 4-6 hours before bedtime.

2. Alcohol

While alcohol might make you drowsy initially, it disrupts your sleep cycle, leading to fragmented and shallow sleep. It's best to limit alcohol consumption, especially in the evening hours.

3. Fatty Foods

Foods high in fat, such as fried and greasy foods, can trigger acid reflux or heartburn, disturbing your sleep. Opt for lighter, easily digestible meals in the evening.

4. Sugary Foods and Drinks

Sugary foods and beverages can cause a rapid spike and subsequent drop in blood sugar levels, leading to wakefulness during the night. Avoid sugary snacks and desserts close to bedtime.

5. Nicotine

Nicotine is a stimulant found in cigarettes and some other tobacco products which can interfere with sleep. It's advisable to avoid all forms of nicotine before bedtime.

6. Excessive Fluids

While it's important to stay hydrated, consuming large amounts of fluids close to bedtime can lead to frequent trips to the bathroom during the night, disrupting your sleep. Limit your fluid intake in the evening hours.

Focusing on food is the most important for achieving good sleep due to its profound impact on sleep-related hormones and bodily functions. The foods we consume directly influence the production of sleep-regulating hormones like serotonin and melatonin, crucial for establishing healthy sleep-wake cycles. 

A well-balanced diet not only supports overall health but also reduces the risk of sleep disorders, facilitating natural and restorative sleep. Moreover, incorporating calming foods and herbal teas enhances relaxation, making it easier to unwind and drift into a peaceful slumber. 

You can also consider including certain sleep-inducing supplements such as the melatonin strips or Melting Strips for Sleep by Panchamrit that contain calming ingredients like chamomile and valerian root. By conscientiously choosing foods that promote relaxation and nourish the body, individuals can significantly improve their sleep quality, leading to enhanced daytime functioning and an overall better quality of life.
