SLEEPING & POOPING…..It’s Connected!

The surprising way your sleep habits are contributing to your gut woes. (Take note if you’re a little constipated). Do you feel like you always have to deal with multiple health issues? Maybe you have trouble sleeping, or you wake up without feeling refreshed. Perhaps you always have a morning headache or have difficulty concentrating. And your digestion hasn’t been good for a while – you feel bloated most days, and worry you’ve developed sensitivity to some of your favorite foods.

What if I told you that your gut and brain are connected, and that your gut could be contributing to your lack of sleep? And that if we look at your health systemically, we might find that you are also dealing with a sleep airway disorder? Everything in your body is linked, and your airway has a surprising effect on your gut – and your gut has a huge influence on your health.


Your Gut-Brain Connection

Your gut is a sophisticated organ, not only responsible for the breakdown and absorption of food. Incredibly, your gut has neural tissue and neurotransmitters embedded in the walls, which make and release hormones such as serotonin. Your gut microbiome is just as fascinating: the colony of bacteria cells that live in your colon actually outnumber the entirety of your human cells by a factor of 10.


Your gut and brain communicate in two main ways

Through the vagus nerve – the longest cranial nerve in your body, which passes from your cranium to your abdomen. The vagus nerve is an information superhighway, communicating both sensory information and movement commands. As it lines such a large section of your body, the vagus nerve has many functions, including the stimulation of the muscles in your heart to make it beat. But the vagus nerve also stimulates the movement of your gut needed in order to digest food.

Your gut also uses the vagus nerve to transmit information up to your brain. The brainstem of the vagus nerve interacts with your hypothalamus and limbic system which interestingly also govern the regulation of your emotions. Studies show that depression and anxiety can often start in the gut.

Through hormones – Your gut microbiome also has a say in the working of your body and brain, through triggering the release of hormones or producing them. The bacteria can communicate with your nervous system, and certain types affect your production of serotonin. By reducing your  serotonin levels, the gut bacteria can interfere with your sleep. Your brain and your guts can enter a vicious circle when it comes to sleep, as poor sleep can have a bad effect on your gut health.

These paths of communication allow for subtle changes in your body, but sometimes the impact of the gut brain connection is more serious, especially regarding your sleep.


7 Ways Your Gut Affects Your Sleep – and Vice Versa

Although modern medicine tends to forget the bigger picture, all of our bodily systems are connected and entwined – nervous, digestive, endocrine, cardiovascular, and so on. While digestion issues or food allergies only appear to affect your toilet habits, they often have a knock on effect, either through your gut’s communications with your brain, or interactions with your immune system.

Your gut and sleep issues interact in the following situations:

  1. Sleep apnea and other sleep airway disorders can impair your gut microbiome. When your microbiome is less diverse, it can affect production of serotonin and melatonin which affects your ability to sleep. In an animal study this disruption caused inflammation and insulin resistance – precursors to heart disease and diabetes.
  2. Changes in the microbiome can provoke inflammation in the body and immune system, and go on to affect your ability to sleep.
  3. The process of dysbiosis, where your gut microbiome is imbalanced or disturbed, can affect the working of your gut, and result in irritable bowel syndrome (IBS), ulcerative colitis, and more.
  4. Sleep deprivation also increases production of B cells that contributes to the body’s defense system, but excess can increase allergies and asthma. Sleep loss and inflammation are intimately linked. Ultimately, a sleep disorder can contribute to food allergy and subsequent gut discomfort.
  5. Increased levels of cytokines created by your immune system make it harder for you to sleep, as they signal for the release of the stress hormone cortisol. If you have insomnia this can cause a vicious cycle. The impact of stress on the gut is huge – it can trigger IBS.
  1. When inflammation is provoked by leaky gut (where bacteria is allowed through the gut wall) or other gastrointestinal disorders, sleep disordered breathing can contribute to the inflammation further.
  2. There is a direct link between a healthy microbiome, good sleep, and good scoring in cognitive ability for older patients. Dysbiosis leads to poor sleep – and poor cognitive abilities.

As you can see, many of these disruptions have a cascading effect, and as such it’s rare to only struggle with one or two of these health concerns. Everything is connected!


How Do I Improve My Sleep and Gut Health?

  1. Maintain a regular sleep / wake routine
  2. Refrain from taking naps during the day
  3. Go to bed only when you are drowsy
  4. Avoid caffeine and alcohol within six hours of bedtime
  5. Avoid the use of nicotine close to bedtime or during the night
  6. Exercise regularly, but avoid strenuous exercise four hours before bedtime
  7. Try and consume your last meal of the day by 8pm
  8. Minimize light, noise & extreme temperatures in the bedroom
  9. Relax before sleep i.e. read a book, listen to music, or take a bath
  10. Avoid using your bed for anything other than sleep or sex
  11. Try making a to-do list before you go to bed
  12. Avoid clock watching
  13. If you have ongoing sleep issues, seek professional medical advice
  14. Avoid the temptation to google on devices directly before sleep

Supplement with probiotics and prebiotics. Probiotics are healthy bacteria you can use to improve the balance of your microbiome, and can be found in live yogurt, kimchi, and sauerkraut. Prebiotics are a type of food indigestible to you, but they feed the good bacteria in your gut. Prebiotics The allium family (onions, garlic etc) have a positive effect on the quality of your non-REM and REM sleep, while a combination of probiotics and prebiotics can improve your metabolism, reducing inflammation, and thereby preventing the cascade of effects from poor sleep…and on that note…GOODNIGHT.
