Sleep Deprivation's Link To Nausea And Sickness Explained

Sleep is essential for the body's overall health, and a lack of it can have a detrimental impact on our digestive health. Nausea is a common symptom of many ailments, and sleep deprivation is one of them. When you don't get enough sleep, your body's immune system goes into overdrive, releasing proteins called cytokines that cause inflammation throughout the body, including in the digestive organs, leading to nausea. This inflammation, if prolonged, can also lead to chronic gastrointestinal disorders.

Additionally, sleep deprivation can negatively impact your dietary choices, causing you to crave unhealthy, high-sugar, fatty, and salty snacks, as well as increasing your caffeine intake. These dietary changes can further upset your stomach and trigger nausea.

To remedy sleep deprivation-induced nausea, it is important to address the underlying sleep issues. Establishing a healthy sleep routine, avoiding screens before bed, and making dietary and lifestyle changes can all help improve sleep quality.

Sleep deprivation and nausea: the role of the immune system

Sleep deprivation can cause nausea due to its impact on the immune system. Sleep plays a crucial role in maintaining immune function integrity and supporting the body's defence against infection and inflammation. When we don't get enough sleep, our immune system's cells go into overdrive, producing proteins called pro-inflammatory cytokines. These substances increase inflammation throughout the body, including the digestive organs, which can trigger nausea and other uncomfortable symptoms.

Studies have linked sleep deprivation to gastrointestinal disorders, including inflammatory bowel disease, irritable bowel syndrome, Crohn's disease, gastroesophageal reflux disease, peptic ulcer, and colon cancer. Sleep deprivation can also increase the risk of heart problems, high blood pressure, diabetes, obesity, and other chronic conditions. It can also affect mental and emotional health, leading to cognitive impairment, mood disturbances, and decreased sex drive.

To remedy nausea caused by sleep deprivation, it is recommended to drink enough water, try sitting quietly, change positions, eat smaller meals, avoid fatty, spicy, or salty foods, get fresh air, and distract yourself with activities like watching a movie or reading a book. Establishing consistent bedtimes and wake-up times, incorporating bedtime routines, removing screens from the bedroom, exercising, and avoiding caffeine, alcohol, cigarettes, and large meals before bedtime can also help improve sleep quality and duration.

Gastrointestinal disorders and nausea

Sleep deprivation has been linked to various gastrointestinal disorders that can cause nausea and other symptoms. Research has shown that people who don't get enough sleep have higher rates of these disorders. Other studies have shown that sleep deprivation increases the symptoms and severity of a diagnosed gastrointestinal disorder.

Inflammatory Bowel Disease (IBD)

IBD is defined by long-term inflammation of the inner lining of the colon, which can cause bleeding and ulcers. Sleep abnormalities can influence the course of this chronic inflammatory condition. IBD patients often experience "significantly prolonged sleep latency, more frequent sleep fragmentation, higher rates of sleeping pill use, decreased daytime energy, increased tiredness, and overall poor sleep quality."

Irritable Bowel Syndrome (IBS)

IBS causes abdominal pain, cramping, discomfort, and a change in bowel habits. Studies have shown that people with IBS have more difficulties with sleep, including taking longer to fall asleep, repeated nighttime waking, and excessive daytime sleepiness. IBS patients may also have altered sleep patterns, spending a larger portion of their night in REM sleep, leading to less restful sleep.

Crohn's Disease

This type of IBD is associated with cramping, weight loss, fever, fatigue, and watery diarrhoea.

Gastroesophageal Reflux Disease (GERD)

With GERD, contents from the stomach back up into the oesophagus, causing a burning feeling in the throat or chest. Sleep disturbances are commonly reported in patients with GERD. Nocturnal reflux can lead to sleep disturbance, further aggravating GERD by prolonging acid contact time and heightening sensory perception.

Peptic Ulcer

A peptic ulcer is a sore in the stomach lining or the small intestine lining, causing burning pain in the stomach. Data on the relationship between sleep disorders and peptic ulcers are sparse, but some studies suggest a higher prevalence of ulcers among shift workers, possibly due to unpredictable meal timing, sleep dysfunction, work stress, and the use of non-steroidal anti-inflammatory drugs.

Colon Cancer

Colon cancer forms tumours that begin in the large intestine. Both shorter and longer sleep durations have been associated with an increased risk of colon cancer. Sleep deprivation can lead to the release of inflammatory cytokines, which can contribute to the development of colorectal cancer.

Dietary choices and nausea

When you're feeling nauseous, it's important to be mindful of your dietary choices. Here are some tips to help alleviate nausea:

• Eat dry, starchy, and bland foods: Crackers, noodles, toast, rice, potatoes, and cereals are easy to digest and may help settle your stomach.
• Stay hydrated: Drink plenty of water and clear fluids to stay hydrated, especially if you've been vomiting or have a fever.
• Avoid fatty, greasy, and fried foods: These types of foods can aggravate nausea and slow down digestion.
• Choose cool or cold foods: Cool and cold foods have less odor, which may make them easier to tolerate and less likely to trigger nausea.
• Avoid strong-smelling foods: The smell of cooking or preparing food can worsen nausea. Opt for cold foods like dairy products, sandwiches, and fruits.
• Sip ginger tea or suck on ginger candy: Ginger has long been used as a remedy for nausea and may help reduce symptoms.
• Eat smaller, more frequent meals: Avoid going too long without eating, as an empty stomach can worsen nausea. Try eating something small every 1-2 hours.
• Avoid caffeine, alcohol, and carbonated drinks: These beverages may worsen nausea, especially if you're already feeling unwell.
• Eat protein-rich meals: Protein helps keep your body strong and reduces the risk of malnutrition, which is important if you're experiencing chronic nausea.
• Avoid high-sugar snacks: Lack of sleep can cause appetite changes, leading to cravings for unhealthy snacks. Opt for nutritious choices instead.

It's important to listen to your body and make dietary choices that work for you. If nausea persists or is accompanied by other symptoms, consult your doctor.

Stress and nausea

Stress-induced nausea is a real thing. When you're under stress, your body releases a flood of hormones to prepare you to face or flee from a perceived threat. These hormones trigger your fight-or-flight response, which affects all of your body's systems, including your digestive system.

Anxiety is a response to stress, and it can cause various psychological and physical symptoms. When you feel overly anxious, you might notice that your heart rate speeds up and your breathing rate increases, and you may experience nausea. This kind of nausea may pass fairly quickly, but sometimes, anxiety-related nausea can make you totally sick to your stomach.

Anxiety disorders that may cause nausea include:

• Generalized anxiety disorder (GAD), also known as chronic anxiety
• Post-traumatic stress disorder (PTSD)
• Social anxiety disorder

If you frequently experience anxiety accompanied by nausea, it can negatively affect your quality of life. Anxiety disorders that aren't addressed can lead to other conditions, such as depression.

There are some things you can do to help manage anxiety and nausea:

• Focus on the present rather than stressing about what may happen later.
• Consider what's happening in the moment, and remind yourself that you're safe and that the feeling will pass.
• Take long, deep breaths.
• Try to distract yourself by listening to your favourite song or counting backward from 100.

There are also a few things you can do to cope with anxiety in the long term:

• Exercise regularly
• Maintain a healthy, balanced diet
• Limit alcohol and caffeine
• Get enough sleep
• Keep up with your friends and maintain your social network
• Have a plan in place (meditation, aromatherapy, or deep breathing exercises you can use when you feel anxious)

If you have chronic anxiety, it’s best to see your primary care physician for a thorough checkup. Your doctor can refer you to licensed professionals who can help determine your triggers, address your anxiety issues, and teach you how to prevent it from getting worse.

How to treat nausea caused by lack of sleep

Nausea caused by lack of sleep can be treated in several ways. Firstly, it is important to address the root cause and improve your sleep schedule. This can be done by establishing a good sleep routine, including consistent sleeping and waking times, avoiding screens before bed, and maintaining a comfortable room temperature.

In addition to improving sleep hygiene, there are several remedies that can help manage nausea:

• Drink enough water throughout the day to stay hydrated.
• Try sipping ginger, peppermint, or chamomile tea, which are known to help with an upset stomach.
• Eat smaller, more frequent meals consisting of bland, easy-to-digest foods such as crackers, toast, potatoes, noodles, or rice.
• Avoid fatty, spicy, or salty foods, as well as caffeine and alcohol, especially close to bedtime, as these can trigger nausea.
• Get some fresh air and sunlight, which can help improve alertness and suppress sleep hormones.
• Take a short walk to increase your alertness and improve excessive daytime sleepiness.
• Listen to music or sounds that are novel and stimulating to help keep you awake.
• Try sitting quietly or changing positions, as moving around may worsen nausea for some people.

If nausea persists or is accompanied by other symptoms, it is important to consult a doctor, as it may indicate a more serious medical condition.
