There is a complex relationship between sleep and digestion, with the two processes influencing each other in several ways. The digestive system continues to work during sleep, but at a slower pace. This is because the body is not consuming any more food or drink, allowing the digestive tissues to repair and grow, fuelled by glucose from earlier meals. However, eating a large meal close to bedtime can negatively impact sleep quality and digestive health. This is because lying down soon after a meal can increase the risk of heartburn or acid reflux, and certain foods can take longer to digest than others.

What You'll Learn
The digestive system slows down during sleep
The digestive system does not shut down during sleep. However, it does slow down. This is because the body is not taking in any more food or drink to digest. During sleep, the body is in "rest and digest" mode, allowing the digestive tissues to repair and grow, fuelled by glucose from earlier meals.
The speed of digestion depends on the type of food consumed, what was drunk, and the individual's metabolism. Whole, plant-based foods and water are digested more quickly, while proteins like eggs, meats, and cheeses take longer to pass through the digestive system.
The digestive system is also impacted by sleep patterns. Irregular sleep patterns can disrupt the digestive pace, and sleep deprivation can disturb the body's hormonal balance. For example, insufficient sleep can elevate ghrelin, the hunger hormone, while reducing leptin, which signals fullness. This can lead to increased food consumption and potential overeating.
Additionally, sleeping positions can affect how the digestive system works. Sleeping on the left side is recommended to reduce the risk of heartburn and acid reflux. Sleeping on the back, especially for those with gastroesophageal reflux disease (GERD), can allow acid to creep back up into the throat, causing a burning sensation and discomfort.

Sleep position affects digestion
Sleep and digestion are intricately linked. While the digestive system continues to work during sleep, it does so at a slower pace. This period of reduced activity allows the digestive tissues to repair and regenerate.
However, eating close to bedtime can disrupt this process, causing issues such as acid reflux, indigestion, and heartburn. These problems can further develop into gastrointestinal distress, negatively impacting sleep quality.
Sleep Position and Digestion
The sleep position can influence digestion, with side sleeping, particularly on the left side, being recommended for improved digestion and reduced heartburn. This position helps separate food and acid from the lower oesophageal sphincter, preventing acid from backing up into the oesophagus. Additionally, gravity aids in waste movement through the ascending colon, transverse colon, and descending colon, encouraging a trip to the bathroom in the morning.
For those who sleep on their front, placing a firm pillow under the hips can raise the bottom of the spine, making sleep more comfortable. Back sleeping, on the other hand, may worsen heartburn and acid reflux, especially for those with GERD, as it allows acid to creep back up into the throat.
While the left side is generally recommended for better digestion, the choice of sleep position should also consider individual comfort and any existing medical conditions. For example, side sleeping can help reduce snoring or sleep apnea by preventing the tongue from falling back and blocking the airway.
In summary, the sleep position can impact digestion, with side sleeping on the left side being recommended for most people to enhance digestion and reduce the risk of certain digestive issues. However, comfort and personal preferences are also essential factors to consider when choosing a sleep position.

Eating before bed can cause acid reflux and indigestion
Certain foods are more likely to trigger acid reflux, including spicy and acidic foods, as well as those high in fat or fibre. Eating a large meal before bed can also worsen existing acid reflux and indigestion symptoms. It is recommended that individuals with gastro-oesophageal reflux disease (GERD) refrain from eating within three hours of going to sleep.
To prevent acid reflux and indigestion at night, it is advised to eat smaller, milder, and less fatty and fibrous meals a few hours before bedtime. Sleeping on the left side is also recommended to enhance digestion. Additionally, sleeping with the head elevated can help manage acid reflux symptoms.

Irregular sleep patterns disrupt digestive pace
The human body operates on circadian rhythms, which include digestive processes. As such, irregular sleep patterns can disrupt the digestive pace in several ways. Firstly, eating at unusual times can disrupt the body's circadian rhythms, leading to digestive disturbances like appetite fluctuations. This is because the digestive system releases hormones that help determine when we feel hungry or full, and a lack of sleep affects the release of these hormones. For example, sleep deprivation can elevate ghrelin, the hunger hormone, while reducing leptin, which signals fullness, potentially leading to increased food consumption and overeating.
Secondly, inadequate sleep weakens the immune system, potentially increasing inflammation within the gut and worsening gastrointestinal symptoms. Poor sleep can also heighten sensitivity to pain, amplifying any discomfort caused by digestive issues. For instance, a lack of sleep can affect the bowel's ability to rest and recuperate, leading to bowel muscle fatigue and reduced bowel movement and function. This can result in constipation, which is often experienced alongside low sleep quality during women's periods.
Additionally, stress caused by a lack of sleep can further impact digestion, as the stress hormone has been shown to affect the digestive process. This creates a challenging cycle where digestive issues can lead to poor sleep, which in turn exacerbates these issues.
To optimize both sleep quality and digestive health, it is recommended to align meal times with circadian rhythms and maintain consistent sleep patterns.

Sleep deprivation disturbs hormonal balance
The digestive system continues to work while we sleep, but at a slower pace. This is because we are not eating or drinking. This period of slower digestion allows our digestive tissues to repair and grow, fuelled by glucose from earlier meals.
Sleep deprivation has been shown to disturb the hormonal balance in the body. Firstly, it elevates ghrelin, the hunger hormone, while reducing leptin, the hormone that signals fullness. This leads to increased food consumption and potential overeating. Sleep loss is associated with an increase in appetite that is excessive in relation to the caloric demands of extended wakefulness.
Secondly, sleep deprivation weakens the immune system, potentially increasing inflammation within the gut and worsening gastrointestinal symptoms. Poor sleep can also heighten sensitivity to pain, amplifying discomfort caused by digestive issues.
Thirdly, sleep disturbances can represent novel risk factors for obesity and type 2 diabetes. Sleep curtailment appears to be an increasingly prevalent behaviour in children, and adolescents may be the most sleep-deprived age group.
Finally, sleep deprivation can affect the release of hormones by the pituitary, the "master" endocrine organ that controls the secretion of other hormones from the peripheral endocrine glands. During deep sleep, sympathetic nervous system activity decreases, and parasympathetic nervous system activity increases. Sleep loss is associated with an elevation of sympathovagal balance, with higher sympathetic but lower parasympathetic tone.

Frequently asked questions
Yes, digestion continues while you sleep, but at a slower pace.
During sleep, the gastrointestinal system slows down, salivation is decreased, and the primary esophageal contraction is less frequent, causing a prolongation of acid clearance.
Whole, plant-based foods and water are easily and quickly digested. Foods that are high in fibre, fat, or spice can aggravate acid reflux and indigestion.
Sleeping on your left side is the best position to enhance your digestion. It can also reduce the risk of heartburn and symptoms of indigestion.
Sleep deprivation can disturb your hormonal balance, elevate the hunger hormone, and reduce the hormone that signals fullness, leading to increased food consumption and potential overeating.
