There is some evidence to suggest that vegans require less sleep than non-vegans. A number of vegans have reported sleeping fewer hours since changing their diet, while still having the energy to work long days and exercise. However, this is not true for all vegans, and some have reported no change in their sleeping patterns.
One theory is that a vegan diet can help to lower levels of inflammation, which can interrupt sleep. In addition, plant-based foods are easier to digest, meaning that sleep is less likely to be disturbed by digestive issues.
However, it is important to note that a vegan diet does not automatically lead to improved sleep. Vegans can be at risk of vitamin B12 deficiency, which is needed to keep sleep-wake cycles in sync, and this can disrupt sleep.

What You'll Learn
Plant-based foods are easier to digest
A vegan or vegetarian diet is often easier for the digestive system to process. This is because it is typically based on plant-based foods, which are less taxing for the body to break down than protein-rich foods like meat.
Less Digestive Discomfort
With plant-based foods, you're less likely to experience bloating, constipation, or a sudden urge to rush to the toilet. This is because vegan and vegetarian diets are usually rich in fibre from fruit, vegetables, and pulses, which promotes healthy digestion and regular bowel movements.
Stable Blood Glucose Levels
The fibre in plant-based diets also helps to stabilise blood glucose levels, which is beneficial for a good night's sleep. In contrast, diets high in refined sugar can cause blood glucose levels to spike and then crash, leading to cravings and disrupted sleep.
Anti-Inflammatory Effects
Plant-based diets are also rich in anti-inflammatory fruits and vegetables, which can help to reduce inflammation in the body. Inflammation can upset the digestive system, irritate the skin, and cause joint pain or period cramps, all of which can interrupt sleep.
Healthier Bowels
The high fibre content of plant-based diets promotes regular bowel movements and reduces the risk of constipation. This is especially beneficial for sleep as it prevents discomfort and the need to get up to use the bathroom during the night.

Vegan diets can be unhealthy
While veganism is often associated with a range of health benefits, it is not inherently a healthy way of eating. A vegan diet can be unhealthy if it is not carefully planned and supplemented.
One of the main pitfalls of veganism is that "vegan" foods are not always healthy. Vegan cakes, sweets, and other junk food are still junk food. Refined sugar, which is common in these foods, can disrupt sleep and negatively impact health. Sugar can cause a spike in blood glucose levels, leading to cravings and disrupted sleep. Additionally, sugary foods tend to be more pro-inflammatory, which can cause digestive issues, skin irritation, and arthritic flare-ups.
Another issue with vegan diets is the risk of nutrient deficiencies. Nutrients like iron, vitamin B12, and calcium are crucial for overall health and wellbeing, and their deficiencies can negatively affect sleep patterns. While some of these nutrients are more readily available in animal-derived foods, there are vegan sources as well. For example, calcium can be found in plant-based diets, often in a better balance with other important nutrients like magnesium. However, a varied diet with whole foods is essential to avoid deficiencies.
Furthermore, switching to a vegan diet requires careful planning to ensure adequate nutrient intake. Vegans need to be mindful of getting enough protein and may need to add it to their meals and snacks. A lack of protein can lead to cravings, low energy levels, mood swings, and deficiencies.
In conclusion, while veganism can offer health benefits, it is important to remember that not all vegan foods are healthy. A well-planned and balanced vegan diet that includes a variety of whole foods and necessary supplements can promote better health and sleep.

Lower levels of inflammation
Inflammation can cause sleep disturbances in several ways, from digestive issues to skin irritation and arthritic flare-ups. A vegan diet can help combat inflammation as it cuts out meat and focuses on anti-inflammatory fruits and vegetables.
A vegan diet can reduce the risk of inflammation-related conditions such as digestive problems, skin irritation, and arthritic flare-ups, which can interfere with sleep. Inflammation can also be caused by a diet high in processed foods or meat, which tend to be more pro-inflammatory. By eliminating these foods, vegans may experience reduced inflammation and improved sleep quality.
Some people who switch to a vegan diet report sleeping less but feeling more rested. They wake up more quickly and feel more energised throughout the day, even with reduced sleep duration. This could be due to the anti-inflammatory properties of a vegan diet, which may reduce inflammation-related sleep disturbances.
However, it is important to note that a vegan diet does not guarantee improved sleep. A well-balanced diet that includes a variety of whole foods and addresses any nutrient deficiencies is crucial for maintaining overall health and wellbeing, including sleep quality. Additionally, individual factors such as hormonal cycles and caffeine intake can also influence sleep patterns.
While a vegan diet may not directly cause a person to need less sleep, it can contribute to lower levels of inflammation, which can positively impact sleep quality and overall health.

Vegans are more susceptible to deficiencies
Nutritional deficiencies can negatively impact sleep, and vegans are at a higher risk of developing certain deficiencies. Nutrients such as iron, vitamin B12, vitamin D, and calcium are crucial for maintaining overall health and wellbeing, and their deficiencies can disrupt sleep patterns.
Vitamin B12, typically found in animal-derived foods, is essential for keeping sleep-wake cycles in sync. A deficiency in vitamin B12 has been linked to insomnia and can even lead to anaemia and nervous system damage. Therefore, vegans need to ensure adequate intake of vitamin B12 through dietary sources such as fortified breakfast cereals, nutritional yeasts, and plant-based milk alternatives.
Additionally, vegans may also be at risk of vitamin D and calcium deficiencies, which are typically obtained from meat, dairy, and eggs. Calcium is essential for bone health, and vitamin D helps regulate calcium absorption and immune function. These deficiencies can have adverse effects on overall health and may indirectly impact sleep quality.
To avoid these deficiencies, it is important for vegans to carefully plan their meals and consider taking supplements. A well-planned vegan diet that includes a variety of whole foods can provide adequate nutrition and promote better sleep.

Vegans are more health-conscious
Vegans and vegetarians tend to be more health-conscious than meat-eaters. They are more aware of health-related issues and invest more time in enhancing their physical and mental well-being. This awareness and conscious approach to health mean that vegans and vegetarians may be more prepared to tackle sleep problems such as insomnia and deprivation. They may also be more interested in improving their quality of sleep overall.
A vegan or vegetarian diet, when done properly, contains plenty of sleep-promoting nutrients such as magnesium and potassium, which can promote the production of serotonin, a feel-good neurotransmitter. Magnesium is also associated with lower levels of inflammation. A diet that contains large amounts of processed foods or meat is more likely to cause inflammation, which can upset the digestive system, irritate the skin, and cause arthritic flare-ups.
However, it is important to note that a vegan diet does not automatically guarantee better sleep. Vegans can be deficient in vitamin B12, which is usually obtained from animal products. Vitamin B12 is needed to speed up reactions in the body, and deficiency can cause anaemia and nervous system damage. Some sleep studies show a correlation between low vitamin B12 and insomnia.
Additionally, while plant-based foods are generally easier to digest, "vegan" foods are not always healthy. Refined sugar, for example, can disrupt healthy sleep patterns. It is important for vegans to be mindful of their nutritional intake and supplement their diets appropriately to ensure they are getting adequate sleep.
